* 🔧 chore: Update file-type dependency to version 21.3.2 in package-lock.json and package.json
- Upgraded the "file-type" package from version 18.7.0 to 21.3.2 to ensure compatibility with the latest features and security updates.
- Added new dependencies related to the updated "file-type" package, enhancing functionality and performance.
* 🔧 chore: Upgrade undici dependency to version 7.24.1 in package-lock.json and package.json
- Updated the "undici" package from version 7.18.2 to 7.24.1 across multiple package files to ensure compatibility with the latest features and security updates.
* 🔧 chore: Upgrade yauzl dependency to version 3.2.1 in package-lock.json
- Updated the "yauzl" package from version 3.2.0 to 3.2.1 to incorporate the latest features and security updates.
* 🔧 chore: Upgrade hono dependency to version 4.12.7 in package-lock.json
- Updated the "hono" package from version 4.12.5 to 4.12.7 to incorporate the latest features and security updates.
* fix: sanitize artifact filenames to prevent path traversal in code output
* test: Mock sanitizeFilename function in process.spec.js to return the original filename
- Added a mock implementation for the `sanitizeFilename` function in the `process.spec.js` test file to return the original filename, ensuring that tests can run without altering the filename during the testing process.
* fix: use path.relative for traversal check, sanitize all filenames, add security logging
- Replace startsWith with path.relative pattern in saveLocalBuffer, consistent
with deleteLocalFile and getLocalFileStream in the same file
- Hoist sanitizeFilename call before the image/non-image branch so both code
paths store the sanitized name in MongoDB
- Log a warning when sanitizeFilename mutates a filename (potential traversal)
- Log a specific warning when saveLocalBuffer throws a traversal error, so
security events are distinguishable from generic network errors in the catch
* test: improve traversal test coverage and remove mock reimplementation
- Remove partial sanitizeFilename reimplementation from process-traversal tests;
use controlled mock returns to verify processCodeOutput wiring instead
- Add test for image branch sanitization
- Use mkdtempSync for test isolation in crud-traversal to avoid parallel worker
collisions
- Add prefix-collision bypass test case (../user10/evil vs user1 directory)
* fix: use path.relative in isValidPath to prevent prefix-collision bypass
Pre-existing startsWith check without path separator had the same class
of prefix-collision vulnerability fixed in saveLocalBuffer.
* fix: add file size limits to conversation import multer instance
* fix: address review findings for conversation import file size limits
* fix: use local jest.mock for data-schemas instead of global moduleNameMapper
The global @librechat/data-schemas mock in jest.config.js only provided
logger, breaking all tests that depend on createModels from the same
package. Replace with a virtual jest.mock scoped to the import spec file.
* fix: move import to top of file, pre-compute upload middleware, assert logger.warn in tests
* refactor: move resolveImportMaxFileSize to packages/api
New backend logic belongs in packages/api as TypeScript. Delete the
api/server/utils/import/limits.js wrapper and import directly from
@librechat/api in convos.js and importConversations.js. Resolver unit
tests move to packages/api; the api/ spec retains only multer behavior
tests.
* chore: rename importLimits to import
* fix: stale type reference and mock isolation in import tests
Update typeof import path from '../importLimits' to '../import' after
the rename. Clear mockLogger.warn in beforeEach to prevent cross-test
accumulation.
* fix: add resolveImportMaxFileSize to @librechat/api mock in convos.spec.js
* fix: resolve jest.mock hoisting issue in import tests
jest.mock factories are hoisted above const declarations, so the
mockLogger reference was undefined at factory evaluation time. Use a
direct import of the mocked logger module instead.
* fix: remove virtual flag from data-schemas mock for CI compatibility
virtual: true prevents the mock from intercepting the real module in
CI where @librechat/data-schemas is built, causing import.ts to use
the real logger while the test asserts against the mock.
* fix: add agent permission check to image upload route
* refactor: remove unused SystemRoles import and format test file for clarity
* fix: address review findings for image upload agent permission check
* refactor: move agent upload auth logic to TypeScript in packages/api
Extract pure authorization logic from agentPermCheck.js into
checkAgentUploadAuth() in packages/api/src/files/agentUploadAuth.ts.
The function returns a structured result ({ allowed, status, error })
instead of writing HTTP responses directly, eliminating the dual
responsibility and confusing sentinel return value. The JS wrapper
in /api is now a thin adapter that translates the result to HTTP.
* test: rewrite image upload permission tests as integration tests
Replace mock-heavy images-agent-perm.spec.js with integration tests
using MongoMemoryServer, real models, and real PermissionService.
Follows the established pattern in files.agents.test.js. Moves test
to sibling location (images.agents.test.js) matching backend convention.
Adds temp file cleanup assertions on 403/404 responses and covers
message_file exemption paths (boolean true, string "true", false).
* fix: widen AgentUploadAuthDeps types to accept ObjectId from Mongoose
The injected getAgent returns Mongoose documents where _id and author
are Types.ObjectId at runtime, not string. Widen the DI interface to
accept string | Types.ObjectId for _id, author, and resourceId so the
contract accurately reflects real callers.
* chore: move agent upload auth into files/agents/ subdirectory
* refactor: delete agentPermCheck.js wrapper, move verifyAgentUploadPermission to packages/api
The /api-only dependencies (getAgent, checkPermission) are now passed
as object-field params from the route call sites. Both images.js and
files.js import verifyAgentUploadPermission from @librechat/api and
inject the deps directly, eliminating the intermediate JS wrapper.
* style: fix import type ordering in agent upload auth
* fix: prevent token TTL race in MCPTokenStorage.storeTokens
When expires_in is provided, use it directly instead of round-tripping
through Date arithmetic. The previous code computed accessTokenExpiry
as a Date, then after an async encryptV2 call, recomputed expiresIn by
subtracting Date.now(). On loaded CI runners the elapsed time caused
Math.floor to truncate to 0, triggering the 1-year fallback and making
the token appear permanently valid — so refresh never fired.
* fix: require OTP verification for 2FA re-enrollment and backup code regeneration
* fix: require OTP verification for account deletion when 2FA is enabled
* refactor: Improve code formatting and readability in TwoFactorController and UserController
- Reformatted code in TwoFactorController and UserController for better readability by aligning parameters and breaking long lines.

- Improved the state management for OTP readiness, ensuring the regenerate button is only enabled when the OTP is ready.
- Cleaned up imports by removing redundant type imports, enhancing code clarity and maintainability.
* chore: lint
* fix: stage 2FA re-enrollment in pending fields to prevent disarmament window
enable2FA now writes to pendingTotpSecret/pendingBackupCodes instead of
overwriting the live fields. confirm2FA performs the atomic swap only after
the new TOTP code is verified. If the user abandons mid-flow, their
existing 2FA remains active and intact.
* fix: add user filter to message deletion to prevent IDOR
* refactor: streamline DELETE request syntax in messages-delete test
- Simplified the DELETE request syntax in the messages-delete.spec.js test file by combining multiple lines into a single line for improved readability. This change enhances the clarity of the test code without altering its functionality.

- Updated tests to cover new race condition scenarios and ensure proper handling of OAuth flows.
* fix: Stale PENDING flow detection and OAuth URL re-issuance
PENDING flows in handleOAuthRequired now check createdAt age — flows
older than 2 minutes are treated as stale and replaced instead of
joined. Fixes the case where a leftover PENDING flow from a previous
session blocks new OAuth initiation.
authorizationUrl is now stored in MCPOAuthFlowMetadata so that when a
second caller joins an active PENDING flow (e.g., the SSE-emitting path
in ToolService), it can re-issue the URL to the user via oauthStart.
* fix: CSRF fallback via active PENDING flow in OAuth callback
When the OAuth callback arrives without CSRF or session cookies (common
in the chat/SSE flow where cookies can't be set on streaming responses),
fall back to validating that a PENDING flow exists for the flowId. This
is safe because the flow was created server-side after JWT authentication
and the authorization code is PKCE-protected.
* test: Extract shared OAuth test server helpers
Move MockKeyv, getFreePort, trackSockets, and createOAuthMCPServer into
a shared helpers/oauthTestServer module. Enhance the test server with
refresh token support, token rotation, metadata discovery, and dynamic
client registration endpoints. Add InMemoryTokenStore for token storage
tests.
Refactor MCPOAuthRaceCondition.test.ts to import from shared helpers.

* refactor: Update decrementCycleCount method for circuit breaker management
- Changed the visibility of the `decrementCycleCount` method in `MCPConnection` from private to public static, allowing it to be called with a server name parameter.
- Updated calls to `decrementCycleCount` in `MCPConnectionFactory` to use the new static method, improving clarity and consistency in circuit breaker management during connection failures and OAuth recovery.
- Enhanced the handling of circuit breaker state by ensuring the method checks for the existence of the circuit breaker before decrementing the cycle count.
* refactor: cycle count decrement on tool listing failure
- Added a call to `MCPConnection.decrementCycleCount` in the `MCPConnectionFactory` to handle cases where unauthenticated tool listing fails, improving circuit breaker management.
- This change ensures that the cycle count is decremented appropriately, maintaining the integrity of the connection recovery process.

- Enhanced test coverage for state mapping functionality to validate the new deletion logic.
* 🧪 test: Add reconnection storm regression tests for MCPConnection
Introduced a comprehensive test suite for reconnection storm scenarios, validating circuit breaker, throttling, cooldown, and timeout fixes. The tests utilize real MCP SDK transports and a StreamableHTTP server to ensure accurate behavior under rapid connect/disconnect cycles and error handling for SSE 400/405 responses. This enhances the reliability of the MCPConnection by ensuring proper handling of reconnection logic and circuit breaker functionality.
* 🔧 fix: Update createUnavailableToolStub to return structured response
Modified the `createUnavailableToolStub` function to return an array containing the unavailable message and a null value, enhancing the response structure. Additionally, added a debug log to skip tool creation when the result is null, improving the handling of reconnection scenarios in the MCP service.
* 🧪 test: Enhance MCP tool creation tests for cache and throttle interactions
Added new test cases for the `createMCPTool` function to validate the caching behavior when tools are unavailable or throttled. The tests ensure that tools are correctly cached as missing and prevent unnecessary reconnects across different users, improving the reliability of the MCP service under concurrent usage scenarios. Additionally, introduced a test for the `createMCPTools` function to verify that it returns an empty array when reconnect is throttled, ensuring proper handling of throttling logic.
* 📝 docs: Update AGENTS.md with testing philosophy and guidelines
Expanded the testing section in AGENTS.md to emphasize the importance of using real logic over mocks, advocating for the use of spies and real dependencies in tests. Added specific recommendations for testing with MongoDB and MCP SDK, highlighting the need to mock only uncontrollable external services. This update aims to improve testing practices and encourage more robust test implementations.
* 🧪 test: Enhance reconnection storm tests with socket tracking and SSE handling
Updated the reconnection storm test suite to include a new socket tracking mechanism for better resource management during tests. Improved the handling of SSE 400/405 responses by ensuring they are processed in the same branch as 404 errors, preventing unhandled cases. This enhances the reliability of the MCPConnection under rapid reconnect scenarios and ensures proper error handling.
* 🔧 fix: Implement cache eviction for stale reconnect attempts and missing tools
Added an `evictStale` function to manage the size of the `lastReconnectAttempts` and `missingToolCache` maps, ensuring they do not exceed a maximum cache size. This enhancement improves resource management by removing outdated entries based on a specified time-to-live (TTL), thereby optimizing the MCP service's performance during reconnection scenarios.
* 🔄 refactor: OAuth Metadata Discovery with Origin Fallback
Updated the `discoverWithOriginFallback` method to improve the handling of OAuth authorization server metadata discovery. The method now retries with the origin URL when discovery fails for a path-based URL, ensuring consistent behavior across `discoverMetadata` and token refresh flows. This change reduces code duplication and enhances the reliability of the OAuth flow by providing a unified implementation for origin fallback logic.
* 🧪 test: Add tests for OAuth Token Refresh with Origin Fallback
Introduced new tests for the `refreshOAuthTokens` method in `MCPOAuthHandler` to validate the retry mechanism with the origin URL when path-based discovery fails. The tests cover scenarios where the first discovery attempt throws an error and the subsequent attempt succeeds, as well as cases where the discovery fails entirely. This enhances the reliability of the OAuth token refresh process by ensuring proper handling of discovery failures.
* chore: imports order
* fix: Improve Base URL Logging and Metadata Discovery in MCPOAuthHandler
Updated the logging to use a consistent base URL object when handling discovery failures in the MCPOAuthHandler. This change enhances error reporting by ensuring that the base URL is logged correctly, and it refines the metadata discovery process by returning the result of the discovery attempt with the base URL, improving the reliability of the OAuth flow.
* fix: add base URL fallback for path-based OAuth discovery in token refresh
The two `refreshOAuthTokens` paths in `MCPOAuthHandler` were missing the
origin-URL fallback that `initiateOAuthFlow` already had. With MCP SDK
1.27.1, `buildDiscoveryUrls` appends the server path to the
`.well-known` URL (e.g. `/.well-known/oauth-authorization-server/mcp`),
which returns 404 for servers like Sentry that only expose the root
discovery endpoint (`/.well-known/oauth-authorization-server`).
Without the fallback, discovery returns null during refresh, the token
endpoint resolves to the wrong URL, and users are prompted to
re-authenticate every time their access token expires instead of the
refresh token being exchanged silently.
Both refresh paths now mirror the `initiateOAuthFlow` pattern: if
discovery fails and the server URL has a non-root path, retry with just
the origin URL.

* refactor: extract discoverWithOriginFallback helper; add tests
Extract the duplicated path-based URL retry logic from both
`refreshOAuthTokens` branches into a single private static helper
`discoverWithOriginFallback`, reducing the risk of the two paths
drifting in the future.
Add three tests covering the new behaviour:
- stored clientInfo path: asserts discovery is called twice (path then
origin) and that the token endpoint from the origin discovery is used
- auto-discovered path: same assertions for the branchless path
- root URL: asserts discovery is called only once when the server URL
already has no path component
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* refactor: use discoverWithOriginFallback in discoverMetadata too
Remove the inline duplicate of the origin-fallback logic from
`discoverMetadata` and replace it with a call to the shared
`discoverWithOriginFallback` helper, giving all three discovery
sites a single implementation.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* test: use mock.calls + .href/.toString() for URL assertions
Replace brittle `toHaveBeenNthCalledWith(new URL(...))` comparisons
with `expect.any(URL)` matchers and explicit `.href`/`.toString()`
checks on the captured call args, consistent with the existing
mock.calls pattern used throughout handler.test.ts.

* chore: Remove unused setValueOnChange prop from MCPServerMenuItem component
* fix: Resolve agent provider endpoint type for file upload support
When using the agents endpoint with a custom provider (e.g., Moonshot),
the endpointType was resolving to "agents" instead of the provider's
actual type ("custom"), causing "Upload to Provider" to not appear in
the file attach menu.
Adds `resolveEndpointType` utility in data-provider that follows the
chain: endpoint (if not agents) → agent.provider → agents. Applied
consistently across AttachFileChat, DragDropContext, useDragHelpers,
and AgentPanel file components (FileContext, FileSearch, Code/Files).
* refactor: Extract useAgentFileConfig hook, restore deleted tests, fix review findings
- Extract shared provider resolution logic into useAgentFileConfig hook

- Remove dead endpointType param from setupMocks in AttachFileMenu test
* fix: Pass resolved provider endpoint to file upload validation
AgentPanel file components (FileContext, FileSearch, Code/Files) were
hardcoding endpointOverride to "agents", causing both client-side
validation (file limits, MIME types) and server-side validation to
use the agents config instead of the provider-specific config.
Adds endpointTypeOverride to UseFileHandling params so endpoint and
endpointType can be set independently. Components now pass the
resolved provider name and type from useAgentFileConfig, so the full
fallback chain (provider → custom → agents → default) applies to
file upload validation on both client and server.
* test: Verify any custom endpoint is document-supported regardless of name
Adds parameterized tests with arbitrary endpoint names (spaces, hyphens,
colons, etc.) confirming that all custom endpoints resolve to
document-supported through resolveEndpointType, both as direct
endpoints and as agent providers.
* fix: Use || for provider fallback, test endpointOverride wiring
- Change providerValue ?? to providerValue || so empty string is
treated as "no provider" consistently with resolveEndpointType
- Add wiring tests to CodeFiles, FileContext, FileSearch verifying
endpointOverride and endpointTypeOverride are passed correctly

* fix: default ALLOW_SHARED_LINKS_PUBLIC to false for security
Shared links were publicly accessible by default when
ALLOW_SHARED_LINKS_PUBLIC was not explicitly set, which could lead to
unintentional data exposure. Users may assume their authentication
settings protect shared links when they do not.
This changes the default behavior so shared links require JWT
authentication unless ALLOW_SHARED_LINKS_PUBLIC is explicitly set to
true.
* Document ALLOW_SHARED_LINKS_PUBLIC in .env.example
Add comment explaining ALLOW_SHARED_LINKS_PUBLIC setting.

* fix: subdirectory redirects
* fix: use path-segment boundary check when stripping BASE_URL prefix
A bare `startsWith(BASE_URL)` matches on character prefix, not path
segments. With BASE_URL="/chat", a path like "/chatroom/c/abc" would
incorrectly strip to "room/c/abc" (no leading slash). Guard with an
exact-match-or-slash check: `p === BASE_URL || p.startsWith(BASE_URL + '/')`.
Also removes the dead `BASE_URL !== '/'` guard — module init already
converts '/' to ''.
* test: add path-segment boundary tests and clarify subdirectory coverage
- Add /chatroom, /chatbot, /app/chatroom regression tests to verify
BASE_URL stripping only matches on segment boundaries
- Clarify useAuthRedirect subdirectory test documents React Router
basename behavior (BASE_URL stripping tested in api-endpoints-subdir)
- Use `delete proc.browser` instead of undefined assignment for cleanup
- Add rationale to eslint-disable comment for isolateModules require
* fix: use relative path and correct instructions in subdirectory test script
- Replace hardcoded /home/danny/LibreChat/.env with repo-root-relative
path so the script works from any checkout location
- Update instructions to use production build (npm run build && npm run
backend) since nginx proxies to :3080 which only serves the SPA after
a full build, not during frontend:dev on :3090
* fix: skip pointless redirect_to=/ for root path and fix jsdom 26+ compat
buildLoginRedirectUrl now returns plain /login when the resolved path
is root — redirect_to=/ adds no value since / immediately redirects
to /c/new after login anyway.
Also rewrites api-endpoints.spec.ts to use window.history.replaceState
instead of Object.defineProperty(window, 'location', ...) which jsdom
26+ no longer allows.
* test: fix request-interceptor.spec.ts for jsdom 26+ compatibility
Switch from jsdom to happy-dom environment which allows
Object.defineProperty on window.location. jsdom 26+ made
location non-configurable, breaking all 8 tests in this file.
* chore: update browser property handling in api-endpoints-subdir test
Changed the handling of the `proc.browser` property from deletion to setting it to false, ensuring compatibility with the current testing environment.

* refactor: improve browser property handling in loadModuleWithBase function
Revised the management of the `proc.browser` property to store the original value before modification, ensuring it is restored correctly after module loading. This enhances the reliability of the testing environment.
* chore: npm audit
- Bumped versions for several packages: `@hono/node-server` to 1.19.10, `@tootallnate/once` to 3.0.1, `hono` to 4.12.5, `serialize-javascript` to 7.0.4, and `svgo` to 2.8.2.
- Removed deprecated `@trysound/sax` package from package-lock.json.
- Updated integrity hashes and resolved URLs in package-lock.json to reflect the new versions.
* chore: update dependencies and package versions
- Bumped `jest-environment-jsdom` to version 30.2.0 in both package.json and client/package.json.
- Updated related Jest packages to version 30.2.0 in package-lock.json, ensuring compatibility with the latest features and fixes.
- Added `svgo` package with version 2.8.2 to package.json for improved SVG optimization.
* chore: add @happy-dom/jest-environment and update test files
- Added `@happy-dom/jest-environment` version 20.8.3 to `package.json` and `package-lock.json` for improved testing environment.
- Updated test files to utilize the new Jest environment, replacing mock implementations of `window.location` with `window.history.replaceState` for better clarity and maintainability.
- Refactored tests in `SourcesErrorBoundary`, `useFocusChatEffect`, `AuthContext`, and `StartupLayout` to enhance reliability and reduce complexity.
* 🔧 fix: Use longest-match in findMatchingPattern, remove deprecated PaLM2/Codey models
findMatchingPattern now selects the longest matching key instead of the
first reverse-order match, preventing cross-provider substring collisions
(e.g., "gpt-5.2-chat-2025-12-11" incorrectly matching Google's "chat-"
pattern instead of OpenAI's "gpt-5.2"). Adds early exit when key length
equals model name length. Reorders aggregateModels spreads so OpenAI is
last (preferred on same-length ties). Removes deprecated PaLM2/Codey
entries from googleModels.
* refactor: re-order models based on more likely usage
* refactor: Improve key matching logic in findMatchingPattern
Updated the findMatchingPattern function to enhance key matching by ensuring case-insensitive comparisons and maintaining the longest match priority. Clarified comments regarding key ordering and performance implications, emphasizing the importance of defining older models first for efficiency and the handling of same-length ties. This refactor aims to improve code clarity and maintainability.
* test: Enhance findMatchingPattern tests for edge cases and performance
Added new test cases to the findMatchingPattern function, covering scenarios such as empty model names, case-insensitive matching, and performance optimizations. Included checks for longest match priority and ensured deprecated PaLM2/Codey models are no longer present in token entries. This update aims to improve test coverage and validate the function's behavior under various conditions.
* test: Update findMatchingPattern test to use last key for exact match validation
Modified the test for findMatchingPattern to utilize the last key from the openAIMap for exact match checks, ensuring the test accurately reflects the expected behavior of the function. This change enhances the clarity and reliability of the test case.
* chore: Update logging format for tool execution handler to improve clarity
* fix: Expand toolkit tools in loadToolDefinitions for event-driven mode
The image_gen_oai toolkit contains both image_gen_oai and image_edit_oai
tools, but the definitions-only path only returned image_gen_oai. This
adds toolkit expansion so child tools are included in definitions, and
resolves child tool names to their parent toolkit constructor at runtime.
* chore: Remove toolkit flag from gemini_image_gen
gemini_image_gen only has a single tool, so it is not a true toolkit.
* refactor: Address review findings for toolkit expansion
- Guard against duplicate constructor calls when parent and child tools
are both in the tools array (Finding 2)
- Consolidate image tool descriptions/schemas — registry now derives from
toolkit objects (oaiToolkit, geminiToolkit) instead of duplicating them,
so env var overrides are respected everywhere (Finding 5)
- Move toolkitExpansion/toolkitParent to toolkits/mapping.ts with
immutable types (Findings 6, 9)
- Add tests for toolkit expansion, deduplication, and mapping
invariants (Finding 1)
- Fix log format to quote each tool individually (Finding 8)
* fix: Correct toolkit constructor lookup to store under requested tool name
The previous dedup guard stored the factory under toolKey (parent name)
instead of tool (requested name), causing the promise loop to miss
child tools like image_edit_oai. Now stores under both the parent key
(for dedup) and the requested name (for lookup), with a memoized
factory to ensure the constructor runs only once.
- Replaced external icon URLs in manifest.json with local SVG assets for Google Search, DALL-E-3, Tavily Search, Calculator, Stable Diffusion, Azure AI Search, and Flux.
- Added new SVG files for Google Search, DALL-E-3, Tavily, Calculator, Stable Diffusion, and Azure AI Search to the assets directory, enhancing performance and reliability by using local resources.

- Updated the MCPOAuthHandler to delete client_id and client_secret from body parameters when using the client_secret_basic authentication method, ensuring adherence to RFC 6749 §2.3.1.
* test(mcp): add tests for OAuth flow handling of client_secret_basic and client_secret_post methods
- Introduced new test cases to verify that the MCPOAuthHandler correctly removes client_id and client_secret from the request body when using client_secret_basic.
- Added tests to ensure proper handling of client_secret_post and none authentication methods, confirming that the correct parameters are included or excluded based on the specified method.
- Enhanced the test suite for completeOAuthFlow to cover various scenarios, ensuring compliance with OAuth 2.0 specifications.
* test(mcp): enhance tests for selectRegistrationAuthMethod and resolveTokenEndpointAuthMethod
- Added new test cases to verify the selection of the first supported credential method from a mixed list in selectRegistrationAuthMethod.
- Included tests to ensure resolveTokenEndpointAuthMethod correctly ignores unsupported preferred methods and handles empty tokenAuthMethods, returning undefined as expected.
- Improved test coverage for various scenarios in the OAuth flow, ensuring compliance with relevant specifications.

* ♻️ refactor: Centralize `buildLoginRedirectUrl` in data-provider
Move `buildLoginRedirectUrl` from `client/src/utils/redirect.ts` into
`packages/data-provider/src/api-endpoints.ts` so the axios 401
interceptor (and any other data-provider consumer) can use the canonical
implementation with the LOGIN_PATH_RE guard and BASE_URL awareness.
The client module now re-exports from `librechat-data-provider`, keeping
all existing imports working unchanged.
* 🔒 fix: Shared link 401 interceptor bypass and redirect loop (#12033)
Fixes three issues in the axios 401 response interceptor that prevented
private shared links (ALLOW_SHARED_LINKS_PUBLIC=false) from working:
1. `window.location.href.includes('share/')` matched the full URL
(including query params and hash), causing false positives. Changed
to `window.location.pathname.startsWith('/share/')`.
2. When token refresh returned no token on a share page, the
interceptor logged and fell through without redirecting, causing an
infinite retry loop via React Query. Now redirects to login using
`buildLoginRedirectUrl()` which preserves the share URL for
post-login navigation.
3. `processQueue` was never called in the no-token branch, leaving
queued requests with dangling promise callbacks. Added
`processQueue(error, null)` before the redirect.
* ✅ test: Comprehensive 401 interceptor tests for shared link auth flow
Rewrite interceptor test suite to cover all shared link auth scenarios:
- Unauthenticated user on share page with failed refresh → redirect
- Authenticated user on share page with failed refresh → redirect
- share/ in query params does NOT bypass the auth header guard
- Login path guard: redirect to plain /login (no redirect_to loop)
- Refresh success: assert exact call count (toBe(3) vs toBeGreaterThan)
Test reliability improvements:
- window.location teardown moved to afterEach (no state leak on failure)
- expect.assertions(N) on all tests (catch silent false passes)
- Shared setWindowLocation helper for consistent location mocking
* ♻️ refactor: Import `buildLoginRedirectUrl` directly from data-provider
Update `AuthContext.tsx` and `useAuthRedirect.ts` to import
`buildLoginRedirectUrl` from `librechat-data-provider` instead of
re-exporting through `~/utils/redirect.ts`.
Convert `redirect.ts` to ESM-style inline exports and remove the
re-export of `buildLoginRedirectUrl`.
* ✅ test: Move `buildLoginRedirectUrl` tests to data-provider
Tests for `buildLoginRedirectUrl` now live alongside the implementation
in `packages/data-provider/specs/api-endpoints.spec.ts`.
Removed the duplicate describe block from the client redirect test file
since it no longer owns that function.
* 🔧 chore: Update @vitejs/plugin-react to version 5.1.4 and clean up package-lock.json

* 🔗 fix: Preserve URL query params during silent token refresh
The silent token refresh on hard navigation was redirecting to '/c/new'
without query params, wiping the URL before ChatRoute could read them.
Now preserves the current URL (pathname + search) as the redirect
fallback, with isSafeRedirect validation.
* 🧭 fix: Apply URL query params in ChatRoute initialization
ChatRoute now reads URL search params (endpoint, model, agent_id, etc.)
and merges them into the preset passed to newConversation(), so the
first conversation init already includes the URL param settings. This
eliminates the race where useQueryParams fired too late.
- Export processValidSettings from useQueryParams for reuse
- Add getNewConvoPreset helper in ChatRoute (used in both NEW_CONVO branches)
- Query params take precedence over model spec defaults
- useQueryParams now waits for endpointsConfig before processing
- Skip redundant newQueryConvo when settings are already applied
- Clean all URL params via setSearchParams after processing
* ✅ test: Update useQueryParams tests for new URL cleanup behavior
- Assert setSearchParams called instead of window.history.replaceState
- Mock endpoints config in deferred submission and timeout tests
* ♻️ refactor: Move processValidSettings to ~/utils and address review findings
- Move processValidSettings/parseQueryValue to createChatSearchParams.ts
(pure utility, not hook-specific)
- Fix processSubmission: use setSearchParams instead of replaceState,
move URL cleanup outside data.text guard
- Narrow endpointsConfig guard: only block settings application, not
prompt-only flows
- Convert areSettingsApplied to stable useCallback ([] deps) with
conversationRef to avoid interval churn on conversation updates
- Replace console.log with logger.log in production paths
- Restore explanatory comment on pendingSubmitRef guard
- Use for...of in processValidSettings (CLAUDE.md preference)
- Remove unused imports from useQueryParams
* 🔧 fix: Add areSettingsApplied to effect deps and fix test mocks
- Restore areSettingsApplied in main effect deps (stable identity with
[] deps, safe to include — satisfies exhaustive-deps lint rule)
- Fix all test getQueryData mocks to properly distinguish between
startupConfig and endpoints keys
- Assert setSearchParams call arguments (URLSearchParams + replace:true)
* ✅ test: Assert empty URLSearchParams in setSearchParams calls
Tighten setSearchParams assertions to verify the params are empty
(toString() === ''), not just that a URLSearchParams instance was passed.
* 🔧 test: Update AuthContext tests to navigate to current URL for redirects
- Modified test cases to assert navigation to the current URL instead of a hardcoded '/c/new' when no stored redirect exists or when falling back from unsafe stored redirects.

* fix: complete OIDC logout implementation
The OIDC logout feature added in #5626 was incomplete:
1. Backend: Missing id_token_hint/client_id parameters required by the
RP-Initiated Logout spec. Keycloak 18+ rejects logout without these.
2. Frontend: The logout redirect URL was passed through isSafeRedirect()
which rejects all absolute URLs. The redirect was silently dropped.
Backend: Add id_token_hint (preferred) or client_id (fallback) to the
logout URL for OIDC spec compliance.
Frontend: Use window.location.replace() for logout redirects from the
backend, bypassing isSafeRedirect() which was designed for user-input
validation.
Fixes#5506
* fix: accept undefined in setTokenHeader to properly clear Authorization header
When token is undefined, delete the Authorization header instead of
setting it to "Bearer undefined". Removes the @ts-ignore workaround
in AuthContext.
* fix: skip axios 401 refresh when Authorization header is cleared
When the Authorization header has been removed (e.g. during logout),
the response interceptor now skips the token refresh flow. This
prevents a successful refresh from canceling an in-progress OIDC
external redirect via window.location.replace().
* fix: guard against undefined OPENID_CLIENT_ID in logout URL
Prevent literal "client_id=undefined" in the OIDC end-session URL
when OPENID_CLIENT_ID is not set. Log a warning when neither
id_token_hint nor client_id is available.
* fix: prevent race condition canceling OIDC logout redirect
The logout mutation wrapper's cleanup (clearStates, removeQueries)
triggers re-renders and 401s on in-flight requests. The axios
interceptor would refresh the token successfully, firing
dispatchTokenUpdatedEvent which cancels the window.location.replace()
navigation to the IdP's end_session_endpoint.
Fix:
- Clear Authorization header synchronously before redirect so the
axios interceptor skips refresh for post-logout 401s
- Add isExternalRedirectRef to suppress silentRefresh and useEffect
side effects during the redirect
- Add JSDoc explaining why isSafeRedirect is bypassed
* test: add LogoutController and AuthContext logout test coverage
LogoutController.spec.js (13 tests):
- id_token_hint from session and cookie fallback
- client_id fallback, including undefined OPENID_CLIENT_ID guard
- Disabled endpoint, missing issuer, non-OpenID user
- post_logout_redirect_uri (custom and default)
- Missing OpenID config and end_session_endpoint
- Error handling and cookie clearing
AuthContext.spec.tsx (3 tests):
- OIDC redirect calls window.location.replace + setTokenHeader
- Non-redirect logout path
- Logout error handling
* test: add coverage for setTokenHeader, axios interceptor guard, and silentRefresh suppression
headers-helpers.spec.ts (3 tests):
- Sets Authorization header with Bearer token
- Deletes Authorization header when called with undefined
- No-op when clearing an already absent header
request-interceptor.spec.ts (2 tests):
- Skips refresh when Authorization header is cleared (the race fix)
- Attempts refresh when Authorization header is present
AuthContext.spec.tsx (1 new test):
- Verifies silentRefresh is not triggered after OIDC redirect
* test: enhance request-interceptor tests with adapter restoration and refresh verification
- Store the original axios adapter before tests and restore it after all tests to prevent side effects.
- Add verification for the refresh endpoint call in the interceptor tests to ensure correct behavior during token refresh attempts.
* test: enhance AuthContext tests with live rendering and improved logout error handling
- Introduced a new `renderProviderLive` function to facilitate testing with silentRefresh.
- Updated tests to use the live rendering function, ensuring accurate simulation of authentication behavior.
- Enhanced logout error handling test to verify that auth state is cleared without external redirects.
* test: update LogoutController tests for OpenID config error handling
- Renamed test suite to clarify that it handles cases when OpenID config is not available.
- Modified test to check for error thrown by getOpenIdConfig instead of returning null, ensuring proper logging of the error message.
* refactor: improve OpenID config error handling in LogoutController
- Simplified error handling for OpenID configuration retrieval by using a try-catch block.
- Updated logging to provide clearer messages when the OpenID config is unavailable.
- Ensured that the end session endpoint is only accessed if the OpenID config is successfully retrieved.

- Set Conversations list role as "rowgroup", which better describes
what is actually going on than "row".
- Increased contrast on placeholder text in ChatForm.
The drag & drop background was practically translucent, which made
it hard to see the rest of the overlay (especially on light mode).
Now, we no longer make the background translucent, so you can see
the overlay clearly.
When content is hidden (or in the background of the active form),
users shouldn't be allowed to access that content. However, right now,
you can use a keyboard (or screen reader) to move over to this content.
By adding `inert`, we make this content no longer accessible when hidden.
I've done this in two places:
- The sidebar is now inert when it's closed.
- When the sidebar is open & the window is small, the content area is
inert (since it's mostly obscured by the sidebar).
* 🔌 fix: Resolve MCP OAuth flow state race condition
The OAuth callback arrives before the flow state is stored because
`createFlow()` returns a long-running Promise that only resolves on
flow COMPLETION, not when the initial PENDING state is persisted.
Calling it fire-and-forget with `.catch(() => {})` meant the redirect
happened before the state existed, causing "Flow state not found"
errors.
Changes:
- Add `initFlow()` to FlowStateManager that stores PENDING state and
returns immediately, decoupling state persistence from monitoring
- Await `initFlow()` before emitting the OAuth redirect so the
callback always finds existing state
- Keep `createFlow()` in the background for monitoring, but log
warnings instead of silently swallowing errors
- Increase FLOWS cache TTL from 3 minutes to 10 minutes to give
users more time to complete OAuth consent screens
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* 🔌 refactor: Revert FLOWS cache TTL change
The race condition fix (initFlow) is sufficient on its own.
TTL configurability should be a separate enhancement via
librechat.yaml mcpSettings rather than a hardcoded increase.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* 🔌 fix: Address PR review — restore FLOWS TTL, fix blocking-path race, clean up dead args
- Restore FLOWS cache TTL to 10 minutes (was silently dropped back to 3)
- Add initFlow before oauthStart in blocking handleOAuthRequired path
to guarantee state persistence before any redirect
- Pass {} to createFlow metadata arg (dead after initFlow writes state)
- Downgrade background monitor .catch from logger.warn to logger.debug
- Replace process.nextTick with Promise.resolve in test (correct semantics)
- Add initFlow TTL assertion test
- Add blocking-path ordering test (initFlow → oauthStart → createFlow)

* 🔗 fix: Normalize MCP OAuth `resource` parameter to match token exchange
The authorization request used the raw resource string from metadata while
the token exchange normalized it through `new URL().href`, causing a
trailing-slash mismatch that Cloudflare's auth server rejected. Canonicalize
the resource URL in both paths so they match.
* 🔧 test: Simplify LeaderElection integration tests for Redis
Refactored the integration tests for LeaderElection with Redis by reducing the number of instances from 100 to 1, streamlining the leadership election process. Updated assertions to verify leadership status and UUID after resignation, improving test clarity and performance. Adjusted timeout to 15 seconds for the single instance scenario.
* 🔧 test: Update LeaderElection test case description for clarity
Modified the description of the test case for leader resignation in the LeaderElection integration tests to better reflect the expected behavior, enhancing clarity and understanding of the test's purpose.
* refactor: `resource` parameter in MCP OAuth authorization URL
Updated the `MCPOAuthHandler` to ensure the `resource` parameter is added to the authorization URL even when an error occurs while retrieving it from metadata. This change improves the handling of invalid resource URLs by using the raw value as a fallback, enhancing the robustness of the authorization process.
* 🪵 refactor: Simplify MCP Transport Log Messages
- Updated the logging in MCPConnection to provide clearer output by explicitly logging the method and ID of messages received and sent, improving traceability during debugging.

- Removed duplicate import of `updateBalance` and `bulkInsertTransactions`, streamlining the code for better readability.
* refactor: add TransactionData type and CANCEL_RATE constant to data-schemas
Establishes a single source of truth for the transaction document shape
and the incomplete-context billing rate constant, both consumed by
packages/api and api/.
* refactor: use proper types in data-schemas transaction methods
- Replace `as unknown as { tokenCredits }` with `lean<IBalance>()`
- Use `TransactionData[]` instead of `Record<string, unknown>[]`
for bulkInsertTransactions parameter
- Add JSDoc noting insertMany bypasses document middleware
- Remove orphan section comment in methods/index.ts
* refactor: use shared types in transactions.ts, fix bulk write logic
- Import CANCEL_RATE from data-schemas instead of local duplicate
- Import TransactionData from data-schemas for PreparedEntry/BulkWriteDeps
- Use tilde alias for EndpointTokenConfig import
- Pass valueKey through to getMultiplier
- Only sum tokenValue for balance-enabled docs in bulkWriteTransactions
- Consolidate two loops into single-pass map
* refactor: remove duplicate updateBalance from Transaction.js
Import updateBalance from ~/models (sourced from data-schemas) instead
of maintaining a second copy. Also import CANCEL_RATE from data-schemas
and remove the Balance model import (no longer needed directly).
* fix: test real spendCollectedUsage instead of IIFE replica
Export spendCollectedUsage from abortMiddleware.js and rewrite the test
file to import and test the actual function. Previously the tests ran
against a hand-written replica that could silently diverge from the real
implementation.
* test: add transactions.spec.ts and restore regression comments
Add 22 direct unit tests for transactions.ts financial logic covering
prepareTokenSpend, prepareStructuredTokenSpend, bulkWriteTransactions,
CANCEL_RATE paths, NaN guards, disabled transactions, zero tokens,
cache multipliers, and balance-enabled filtering.
Restore critical regression documentation comments in
recordCollectedUsage.spec.js explaining which production bugs the
tests guard against.
* fix: widen setValues type to include lastRefill
The UpdateBalanceParams.setValues type was Partial<Pick<IBalance,
'tokenCredits'>> which excluded lastRefill — used by
createAutoRefillTransaction. Widen to also pick 'lastRefill'.
* test: use real MongoDB for bulkWriteTransactions tests
Replace mock-based bulkWriteTransactions tests with real DB tests using
MongoMemoryServer. Pure function tests (prepareTokenSpend,
prepareStructuredTokenSpend) remain mock-based since they don't touch
DB. Add end-to-end integration tests that verify the full prepare →
bulk write → DB state pipeline with real Transaction and Balance models.
* chore: update @librechat/agents dependency to version 3.1.54 in package-lock.json and related package.json files
* test: add bulk path parity tests proving identical DB outcomes
Three test suites proving the bulk path (prepareTokenSpend/
prepareStructuredTokenSpend + bulkWriteTransactions) produces
numerically identical results to the legacy path for all scenarios:
- usage.bulk-parity.spec.ts: mirrors all legacy recordCollectedUsage
tests; asserts same return values and verifies metadata fields on
the insertMany docs match what spendTokens args would carry
- transactions.bulk-parity.spec.ts: real-DB tests using actual
getMultiplier/getCacheMultiplier pricing functions; asserts exact
tokenValue, rate, rawAmount and balance deductions for standard
tokens, structured/cache tokens, CANCEL_RATE, premium pricing,
multi-entry batches, and edge cases (NaN, zero, disabled)
- Transaction.spec.js: adds describe('Bulk path parity') that mirrors
7 key legacy tests via recordCollectedUsage + bulk deps against
real MongoDB, asserting same balance deductions and doc counts
* refactor: update llmConfig structure to use modelKwargs for reasoning effort
Refactor the llmConfig in getOpenAILLMConfig to store reasoning effort within modelKwargs instead of directly on llmConfig. This change ensures consistency in the configuration structure and improves clarity in the handling of reasoning properties in the tests.
* test: update performance checks in processAssistantMessage tests
Revise the performance assertions in the processAssistantMessage tests to ensure that each message processing time remains under 100ms, addressing potential ReDoS vulnerabilities. This change enhances the reliability of the tests by focusing on maximum processing time rather than relative ratios.
* test: fill parity test gaps — model fallback, abort context, structured edge cases
- usage.bulk-parity: add undefined model fallback test
- transactions.bulk-parity: add abort context test (txns inserted,
balance unchanged when balance not passed), fix readTokens type cast
- Transaction.spec: add 3 missing mirrors — balance disabled with
transactions enabled, structured transactions disabled, structured
balance disabled
* fix: deduct balance before inserting transactions to prevent orphaned docs
Swap the order in bulkWriteTransactions: updateBalance runs before
insertMany. If updateBalance fails (after exhausting retries), no
transaction documents are written — avoiding the inconsistent state
where transactions exist in MongoDB with no corresponding balance
deduction.
* chore: import order
* test: update config.spec.ts for OpenRouter reasoning in modelKwargs
Same fix as llm.spec.ts — OpenRouter reasoning is now passed via
modelKwargs instead of llmConfig.reasoning directly.
AccountSettings was using Select, but it makes more sense (for a11y)
to use Menu. The Select has the wrong role & behavior for the purpose
of AccountSettings; the "listbox" role it uses is for selecting
values in a form.
Menu matches the actual content better for screen readers; the
"menu" role is more appropriate for selecting one of a number of links.

* fix: Use correct endpoint for file validation in agent panel uploads
Agent panel file uploads (FileSearch, FileContext, Code/Files) were validating against the active conversation's endpoint config instead of the agents endpoint config. This caused incorrect file size limits when the active chat used a different endpoint.
Add endpointOverride option to useFileHandling so callers can specify the correct endpoint for validation independent of the active conversation.
* fix: Use agents endpoint config for agent panel file upload validation
Agent panel file uploads (FileSearch, FileContext, Code/Files) validated
against the active conversation's endpoint config instead of the agents

- Bumped rimraf version from 6.1.2 to 6.1.3 in package.json and package-lock.json files for improved performance and compatibility.
* fix: Prevent recursive login redirect loop
buildLoginRedirectUrl() would blindly encode the current URL into a
redirect_to param even when already on /login, causing infinite nesting
(/login?redirect_to=%2Flogin%3Fredirect_to%3D...). Guard at source so
it returns plain /login when pathname starts with /login.
Also validates redirect_to in the login error handler with isSafeRedirect
to close an open-redirect vector, and removes a redundant /login guard
from useAuthRedirect now handled by the centralized check.
* 🔀 fix: Handle basename-prefixed login paths and remove double URL decoding
buildLoginRedirectUrl now uses isLoginPath() which matches /login,
/librechat/login, and /login/2fa — covering subdirectory deployments
where window.location.pathname includes the basename prefix.
Remove redundant decodeURIComponent calls on URLSearchParams.get()
results (which already returns decoded values) in getPostLoginRedirect,
Login.tsx, and AuthContext login error handler. The extra decode could
throw URIError on inputs containing literal percent signs.
* 🔀 fix: Tighten login path matching and add onError redirect tests
Replace overbroad `endsWith('/login')` with a single regex
`/(^|\/)login(\/|$)/` that matches `/login` only as a full path
segment. Unifies `isSafeRedirect` and `buildLoginRedirectUrl` to use
the same `LOGIN_PATH_RE` constant — no more divergent definitions.
Add tests for the AuthContext onError redirect_to preservation logic
(valid path preserved, open-redirect blocked, /login loop blocked),
and a false-positive guard proving `/c/loginhistory` is not matched.
Update JSDoc on `buildLoginRedirectUrl` to document the plain `/login`
early-return, and add explanatory comment in AuthContext `onError`
for why `buildLoginRedirectUrl()` cannot be used there.
* test: Add unit tests for AuthContextProvider login error handling
Introduced a new test suite for AuthContextProvider to validate the handling of login errors and the preservation of redirect parameters. The tests cover various scenarios including valid redirect preservation, open-redirect prevention, and recursive redirect prevention. This enhances the robustness of the authentication flow and ensures proper navigation behavior during login failures.

* refactor: Enhance document processing to support additional Excel MIME types
Updated the document processing logic to utilize a regex for matching Excel MIME types, improving flexibility in handling various Excel file formats. Added tests to ensure correct parsing of new MIME types, including multiple Excel variants and OpenDocument formats. Adjusted file configuration to include these MIME types for better recognition in the file processing service.
* feat: Add support for additional OpenDocument MIME types in file processing
Enhanced the document processing service to support ODT, ODP, and ODG MIME types. Updated tests to verify correct routing through the OCR strategy for these new formats. Adjusted documentation to reflect changes in handled MIME types for improved clarity.
* fix: populate userMessage.files before first DB save
* fix: ESLint error fixed
* fix: deduplicate file-population logic and add test coverage
Extract `buildMessageFiles` helper into `packages/api/src/utils/message`
to replace three near-identical loops in BaseClient and both agent
controllers. Fixes set poisoning from undefined file_id entries, moves
file population inside the skipSaveUserMessage guard to avoid wasted
work, and adds full unit test coverage for the new behavior.

* Allow setting the claim field to be used when OpenID login is configured
* fix(openid): harden getOpenIdEmail and expand test coverage
Guard against non-string claim values in getOpenIdEmail to prevent a
TypeError crash in isEmailDomainAllowed when domain restrictions are
configured. Improve warning messages to name the fallback chain
explicitly and distinguish missing vs. non-string claim values.
Fix the domain-block error log to record the resolved identifier rather
than userinfo.email, which was misleading when OPENID_EMAIL_CLAIM
resolved to a different field (e.g. upn).
Fix a latent test defect in openIdJwtStrategy.spec.js where the
~/server/services/Config mock exported getCustomConfig instead of
getAppConfig, the symbol actually consumed by openidStrategy.js.
Add refreshController tests covering the OPENID_EMAIL_CLAIM paths,
which were previously untested despite being a stated fix target.
Expand JWT strategy tests with null-payload, empty/whitespace
OPENID_EMAIL_CLAIM, migration-via-preferred_username, and call-order
assertions for the findUser lookup sequence.
* test(auth): enhance AuthController and openIdJwtStrategy tests for openidId updates
Added a new test in AuthController to verify that the openidId is updated correctly when a migration is triggered during the refresh process. Expanded the openIdJwtStrategy tests to include assertions for the updateUser function, ensuring that the correct parameters are passed when a user is found with a legacy email. This improves test coverage for OpenID-related functionality.

* fix: clear heavy config state after processStream to prevent memory leaks
Break the reference chain from LangGraph's internal __pregel_scratchpad
through @langchain/core RunTree.extra[lc:child_config] into the
AsyncLocalStorage context captured by timers and I/O handles.
After stream completion, null out symbol-keyed scratchpad properties
(currentTaskInput), config.configurable, and callbacks. Also call
Graph.clearHeavyState() to release config, signal, content maps,
handler registry, and tool sessions.
* chore: fix imports for memory utils
* chore: add circular dependency check in API build step
Enhanced the backend review workflow to include a check for circular dependencies during the API build process. If a circular dependency is detected, an error message is displayed, and the process exits with a failure status.
* chore: update API build step to include circular dependency detection
Modified the backend review workflow to rename the API package installation step to reflect its new functionality, which now includes detection of circular dependencies during the build process.
* chore: add memory diagnostics option to .env.example
Included a commented-out configuration option for enabling memory diagnostics in the .env.example file, which logs heap and RSS snapshots every 60 seconds when activated.
* chore: remove redundant agentContexts cleanup in disposeClient function
Streamlined the disposeClient function by eliminating duplicate cleanup logic for agentContexts, ensuring efficient memory management during client disposal.
* refactor: move runOutsideTracing utility to utils and update its usage
Refactored the runOutsideTracing function by relocating it to the utils module for better organization. Updated the tool execution handler to utilize the new import, ensuring consistent tracing behavior during tool execution.
* refactor: enhance connection management and diagnostics

* 🔧 chore: Update `@eslint/eslintrc` and related dependencies in `package-lock.json` and `package.json` to latest versions for improved stability and performance
* 🔧 chore: Update `postcss-preset-env` to version 11.2.0 in `package-lock.json` and `client/package.json`, and add `eslint` dependency in `package.json` for improved linting support
* fix: Separate MCP GET SSE body timeout from POST and suppress SDK-internal stream recovery
- Add a dedicated GET Agent with a configurable `sseReadTimeout` (default 5 min,
matching the Python MCP SDK) so idle SSE streams time out independently of POST
requests, preventing the reconnect-loop log flood described in Discussion #11230.
- Suppress "SSE stream disconnected" and "Failed to reconnect SSE stream" errors
in setupTransportErrorHandlers — these are SDK-internal recovery events, not
transport failures. "Maximum reconnection attempts exceeded" still escalates.
- Add optional `sseReadTimeout` to BaseOptionsSchema for per-server configuration.
- Add 6 tests: agent timeout separation, custom sseReadTimeout, SSE disconnect
suppression (3 unit), and a real-server integration test proving the GET stream
recovers without a full transport rebuild.
* fix: Refactor MCP connection timeouts and error handling
- Updated the `DEFAULT_SSE_READ_TIMEOUT` to use a constant for better readability.
- Introduced internal error message constants for SSE stream disconnection and reconnection failures to improve maintainability.
- Enhanced type safety in tests by ensuring the options symbol is defined before usage.
- Updated the `sseReadTimeout` in `BaseOptionsSchema` to enforce positive values, ensuring valid configurations.
* chore: Update SSE read timeout documentation format in BaseOptionsSchema
- Changed the default timeout value comment in BaseOptionsSchema to use an underscore for better readability, aligning with common formatting practices.
* fix(a11y): hide collapsed thinking content from screen readers and link toggle to controlled region
The thinking/reasoning toggle button visually collapsed content using a CSS
grid animation (gridTemplateRows: 0fr + overflow-hidden), but the content
remained in the DOM and fully accessible to screen readers, cluttering the
reading flow for assistive technology users.
- Add aria-hidden={!isExpanded} to the collapsible content region in both
the legacy Thinking component and the modern Reasoning component, so
screen readers skip collapsed thoughts entirely
- Add role="region" and a unique id (via useId) to each collapsible content
div, giving it a semantic landmark for assistive technology
- Add contentId prop to the shared ThinkingButton and wire it to
aria-controls on the toggle button, establishing an explicit relationship
between the button and the region it expands/collapses
- aria-expanded was already present on the button; combined with
aria-controls, screen readers can now fully convey the toggle state and
its target
* fix(a11y): add aria-label to collapsible content regions in Thinking and Reasoning components
Enhanced accessibility by adding aria-label attributes to the collapsible content regions in both the Thinking and Reasoning components. This change ensures that screen readers can provide better context for users navigating through the content.
* fix(a11y): update roles and aria attributes in Thinking and Reasoning components
Changed role from "region" to "group" for collapsible content areas in both Thinking and Reasoning components to better align with ARIA practices. Updated aria-hidden to handle undefined values correctly and ensured contentId is passed to relevant components for improved accessibility and screen reader support.

* feat: add aws bedrock upload to provider support
* chore: address copilot comments
* feat: add shared Bedrock document format types and MIME mapping
Bedrock Converse API accepts 9 document formats beyond PDF. Add
BedrockDocumentFormat union type, MIME-to-format mapping, and helpers
in data-provider so both client and backend can reference them.
* refactor: generalize Bedrock PDF validation to support all document types
Rename validateBedrockPdf to validateBedrockDocument with MIME-aware
logic: 4.5MB hard limit applies to all types, PDF header check only
runs for application/pdf. Adds test coverage for non-PDF documents.
* feat: support all Bedrock document formats in encoding pipeline
Widen file type gates to accept csv, doc, docx, xls, xlsx, html, txt,
md for Bedrock. Uses shared MIME-to-format map instead of hardcoded
'pdf'. Other providers' PDF-only paths remain unchanged.
* feat: expand Bedrock file upload UI to accept all document types
Add 'image_document_extended' upload type for Bedrock with accept
filters for all 9 supported formats. Update drag-and-drop validation
to use isBedrockDocumentType helper.
* fix: route Bedrock document types through provider pipeline
* fix: serve cached presigned URLs on agent list cache hits
On a cache hit the list endpoint was skipping the S3 refresh and
returning whatever presigned URL was stored in MongoDB, which could be
expired if the S3 URL TTL is shorter than the 30-minute cache window.
refreshListAvatars now collects a urlCache map (agentId -> refreshed
filepath) alongside its existing stats. The controller stores this map
in the cache instead of a plain boolean and re-applies it to every
paginated response, guaranteeing clients always receive a URL that was
valid as of the last refresh rather than a potentially stale DB value.
* fix: improve avatar refresh cache handling and logging
Updated the avatar refresh logic to validate cached refresh data before proceeding with S3 URL updates. Enhanced logging to exclude sensitive `urlCache` details while still providing relevant statistics. Added error handling for cache invalidation during avatar updates to ensure robustness.
* fix: update avatar refresh logic to clear urlCache on no change
Modified the avatar refresh function to clear the urlCache when no new path is generated, ensuring that stale URLs are not retained. This change improves cache handling and aligns with the updated logic for avatar updates.
* fix: enhance avatar refresh logic to handle legacy cache entries
Updated the avatar refresh logic to accommodate legacy boolean cache entries, ensuring they are treated as cache misses and triggering a refresh. The cache now stores a structured `urlCache` map instead of a boolean, improving cache handling. Added tests to verify correct behavior for cache hits and misses, ensuring clients receive valid URLs based on the latest refresh.
* feat: Added "document parser" OCR strategy
The document parser uses libraries to parse the text out of known document types.
This lets LibreChat handle some complex document types without having to use a
secondary service (like Mistral or standing up a RAG API server).
To enable the document parser, set the ocr strategy to "document_parser" in
librechat.yaml.
We now support:
- PDFs using pdfjs
- DOCX using mammoth
- XLS/XLSX using SheetJS
(The associated packages were also added to the project.)
* fix: applied Copilot code review suggestions
- Properly calculate length of text based on UTF8.
- Avoid issues with loading / blocking PDF parsing.
* fix: improved docs on parseDocument()
* chore: move to packages/api for TS support
* refactor: make document processing the default ocr strategy

* test: add unit tests for processAgentFileUpload functionality
- Introduced a new test suite for the processAgentFileUpload function in process.spec.js.
- Implemented various test cases to validate OCR strategy selection based on file types, including PDF, DOCX, XLSX, and XLS.
- Mocked dependencies to ensure isolated testing of file upload handling and strategy selection logic.
- Enhanced coverage for scenarios involving OCR capability checks and default strategy fallbacks.
* chore: update pdfjs-dist version and enhance document parsing tests
- Bumped pdfjs-dist dependency to version 5.4.624 in both api and packages/api.
- Refactored document parsing tests to use 'originalname' instead of 'filename' for file objects.
- Added a new test case for parsing XLS files to improve coverage of document types supported by the parser.
- Introduced a sample XLS file for testing purposes.
* feat: enforce text size limit and improve OCR fallback handling in processAgentFileUpload
- Added a check to ensure extracted text does not exceed the 15MB storage limit, throwing an error if it does.
- Refactored the OCR handling logic to improve fallback behavior when the configured OCR fails, ensuring a more robust document processing flow.
- Enhanced unit tests to cover scenarios for oversized text and fallback mechanisms, ensuring proper error handling and functionality.
* fix: correct OCR URL construction in performOCR function
- Updated the OCR URL construction to ensure it correctly appends '/ocr' to the base URL if not already present, improving the reliability of the OCR request.

* 🪣 fix: S3 path-style URL support for MinIO, R2, and custom endpoints
`extractKeyFromS3Url` now uses `AWS_BUCKET_NAME` to automatically detect and
strip the bucket prefix from path-style URLs, fixing `NoSuchKey` errors on URL
refresh for any S3-compatible provider using a custom endpoint (MinIO, Cloudflare
R2, Hetzner, Backblaze B2, etc.). No additional configuration required — the
bucket name is already a required env var for S3 to function.
`initializeS3` now passes `forcePathStyle: true` to the S3Client constructor
when `AWS_FORCE_PATH_STYLE=true` is set. Required for providers whose SSL
certificates do not support virtual-hosted-style bucket subdomains (e.g. Hetzner
Object Storage), which previously caused 401 / SignatureDoesNotMatch on upload.
Additional fixes:
- Suppress error log noise in `extractKeyFromS3Url` catch path: plain S3 keys
no longer log as errors, only inputs that start with http(s):// do
- Fix test env var ordering so module-level constants pick up `AWS_BUCKET_NAME`
and `S3_URL_EXPIRY_SECONDS` correctly before the module is required
- Add missing `deleteRagFile` mock and assertion in `deleteFileFromS3` tests
- Add `AWS_BUCKET_NAME` cleanup to `afterEach` to prevent cross-test pollution
- Add `initializeS3` unit tests covering endpoint, forcePathStyle, credentials,
singleton, and IRSA code paths
- Document `AWS_FORCE_PATH_STYLE` in `.env.example`, `dotenv.mdx`, and `s3.mdx`
* 🪣 fix: Enhance S3 URL key extraction for custom endpoints
Updated `extractKeyFromS3Url` to support precise key extraction when using custom endpoints with path-style URLs. The logic now accounts for the `AWS_ENDPOINT_URL` and `AWS_FORCE_PATH_STYLE` environment variables, ensuring correct key handling for various S3-compatible providers.
Added unit tests to verify the new functionality, including scenarios for endpoints with base paths. This improves compatibility and reduces potential errors when interacting with S3-like services.
* fix: handle space/comma-separated string roles claim in OpenID strategy
When an OpenID provider returns the roles claim as a delimited string
(e.g. "role1 role2 admin"), the previous code wrapped the entire string
as a single array element, causing role checks to always fail even for users with the required role.
Split string claims on whitespace and commas before comparison so that
both array and delimited-string formats are handled correctly.
Adds regression tests for space-separated, comma-separated, mixed, and
non-matching delimited string cases.
* fix: enhance admin role handling in OpenID strategy
Updated the OpenID strategy to correctly handle admin roles specified as space-separated or comma-separated strings. The logic now splits these strings into an array for accurate role checks.
Added tests to verify that admin roles are granted or denied based on the presence of the specified admin role in the delimited string format.
- Removed the extraction of access token from the Authorization header.
- Implemented logic to use the federated access token from the user object.
- Added error handling for missing federated access token.
- Updated related documentation in GraphTokenService to reflect changes in access token usage.
- Introduced unit tests for various scenarios in AuthController.spec.js to ensure proper functionality.

- Implemented logic to prevent overwriting explicit SHARE values provided in the update, preserving user intent.
- Enhanced unit tests to cover various scenarios, including migration from SHARED_GLOBAL to SHARE and ensuring orphaned SHARED_GLOBAL fields are cleaned up appropriately.
* fix: route to new conversation when conversation not found
* Addressed PR feedback
* fix: Robust 404 conversation redirect handling
- Extract `isNotFoundError` utility to `utils/errors.ts` so axios stays
contained in one place rather than leaking into route/query layers
- Add `initialConvoQuery.isError` to the useEffect dependency array so
the redirect actually fires when the 404 response arrives after other
deps have already settled (was the root cause of the blank screen)
- Show a warning toast so users understand why they were redirected
- Add `com_ui_conversation_not_found` i18n key

When all subscribers left a stream, both RedisEventTransport and
InMemoryEventTransport deleted the entire stream state, destroying
the allSubscribersLeftCallbacks and abortCallbacks registered by
GenerationJobManager.createJob(). On the next subscribe/unsubscribe
cycle, the callback that resets hasSubscriber was gone, causing
syncReorderBuffer to be skipped on subsequent reconnects. This led
to the reorder buffer expecting seq 0 while the publisher was at
seq 300+, triggering a 500ms force-flush timeout and "skipping N
missing messages" warnings.
Fix: preserve stream state (callbacks, abort handlers) when the last
subscriber leaves instead of deleting it. State is fully cleaned up
by cleanup() when the job completes, aborts, or is collected by
periodic orphan cleanup.
* fix: Redis scalability improvements for high-throughput deployments
Replace INCR+check+DECR race in concurrency middleware with atomic Lua
scripts. The old approach allowed 3-4 concurrent requests through a
limit of 2 at 300 req/s because another request could slip between the
INCR returning and the DECR executing. The Lua scripts run atomically
on the Redis server, eliminating the race window entirely.
Add exponential backoff with jitter to all three Redis retry strategies
(ioredis single-node, cluster, keyv). Previously all instances retried
at the same millisecond after an outage, causing a connection storm.
Batch the RedisJobStore cleanup loop into parallel chunks of 50. With
1000 stale jobs, this reduces cleanup from ~20s of sequential calls to
~2s. Also pipeline appendChunk (xadd + expire) into a single round-trip
and refresh TTL on every chunk instead of only the first, preventing
TTL expiry during long-running streams.
Propagate publish errors in RedisEventTransport.emitDone and emitError
so callers can detect dropped completion/error events. emitChunk is left
as swallow-and-log because its callers fire-and-forget without await.
Add jest.config.js for the API package with babel TypeScript support and
path alias resolution. Fix existing stream integration tests that were
silently broken due to missing USE_REDIS_CLUSTER=false env var.
* chore: Migrate Jest configuration from jest.config.js to jest.config.mjs
Removed the old jest.config.js file and integrated the Jest configuration into jest.config.mjs, adding Babel TypeScript support and path alias resolution. This change streamlines the configuration for the API package.
* fix: Ensure Redis retry delays do not exceed maximum configured delay
Updated the delay calculation in Redis retry strategies to enforce a maximum delay defined in the configuration. This change prevents excessive delays during reconnection attempts, improving overall connection stability and performance.
* fix: Update RedisJobStore cleanup to handle job failures gracefully
Changed the cleanup process in RedisJobStore to use Promise.allSettled instead of Promise.all, allowing for individual job failures to be logged without interrupting the entire cleanup operation. This enhances error handling and provides better visibility into issues during job cleanup.
* 🐛 fix: Normalize `output_text` blocks in Responses API input conversion
Treat `output_text` content blocks the same as `input_text` when
converting Responses API input to internal message format. Previously,
assistant messages containing `output_text` blocks fell through to the
default handler, producing `{ type: 'output_text' }` without a `text`
field, which caused downstream provider adapters (e.g. Bedrock) to fail
with "Unsupported content block type: output_text".

* refactor: Remove ChatModelStreamHandler from OpenAI and Responses controllers
Eliminated the ChatModelStreamHandler from both OpenAIChatCompletionController and createResponse functions to streamline event handling. This change simplifies the code by relying on existing handlers for message deltas and reasoning deltas, enhancing maintainability and reducing complexity in the agent's event processing logic.
* feat: Enhance input conversion in Responses API
Updated the `convertInputToMessages` function to handle additional content types, including `input_file` and `refusal` blocks, ensuring they are converted to appropriate message formats. Implemented null filtering for content arrays and default values for missing fields, improving robustness. Added comprehensive unit tests to validate these changes and ensure correct behavior across various input scenarios.
* fix: Forward upstream provider status codes in error responses
Updated error handling in OpenAIChatCompletionController and createResponse functions to forward upstream provider status codes (e.g., Anthropic 400s) instead of masking them as 500. This change improves error reporting by providing more accurate status codes and error types, enhancing the clarity of error responses for clients.

* 🔧 refactor: Simplify Event Handling with Consumer Callbacks only
Removed direct handling of tool calls from the ModelEndHandler and using ChatModelStreamHandler outside of graph contexts, as are now managed within the graph execution context to maintain it as a producer of events, and the model end handler as a consumer. This change eliminates potential race conditions and streamlines the processing of model end events.
/**
* handleToolCalls is now called from within the graph execution context
* (Graph.createCallModel, after attemptInvoke) rather than here in the
* stream consumer. This eliminates the race condition where ToolNode
* could read toolCallStepIds before this handler had populated it,
* since the stream consumer and graph execution run concurrently.

* 📦 chore: Update `@librechat/agents` to v3.1.50
* chore: Prevent empty text parts in conversation export function
Added a check to return an empty array if the text part of the conversation is empty or consists only of whitespace, ensuring cleaner data handling in the export process.
* chore: Update .env.example to include CONTINUE_ON_UNCAUGHT_EXCEPTION variable
Added documentation for the CONTINUE_ON_UNCAUGHT_EXCEPTION environment variable, which allows the app to continue running after encountering uncaught exceptions. This change is not recommended for production environments unless necessary.
* fix: handle MongoDB connection errors to prevent process crashes
Add mongoose.connection.on('error') listener in connect.js to catch
connection-level errors emitted by MongoDB driver's SDAM monitoring.
Without this listener, these errors become uncaught exceptions per
Node.js EventEmitter behavior.
Also add MongoDB error patterns to the uncaughtException handler in
server/index.js as defense-in-depth, following the same pattern used
for GoogleGenerativeAI, Meilisearch, and OpenAI errors.
Fixes#11808
* style: fix prettier formatting in uncaughtException handler
* refactor: move error listener to module level
* fix: use precise MongoDB error matching in uncaughtException handler
* fix: replace process.exit(1) with graceful error logging
Instead of maintaining a growing list of error patterns that should
not crash the process, invert the default behavior: log all unhandled
errors and keep running. The existing specific handlers are preserved
for their contextual log messages.
This prevents process crashes from any transient error (MongoDB timeouts,
network issues, third-party library bugs) without needing to add new
patterns each time a new error type is encountered. Unnecessary restarts
are expensive as they trigger full Meilisearch re-syncs under load.
* fix: address review feedback
- connect.js: pass full error object to logger instead of just message
- server/index.js: add optional chaining for nullish err
- server/index.js: make crash-on-unknown-error opt-in via
CRASH_ON_UNCAUGHT_EXCEPTION env var (defaults to graceful logging)
* fix: rename to CONTINUE_ON_UNCAUGHT_EXCEPTION, default to exit

The express session cookie maxAge (SESSION_EXPIRY, default 15 min) is
shorter than the OIDC token lifetime (~1 hour). When OPENID_REUSE_TOKENS
is enabled, the refresh token was stored only in the express session
(req.session.openidTokens). After the session expired, the refresh token
was lost, causing "Refresh token not provided" on the next refresh
attempt and signing the user out. Re-login via OIDC would succeed
immediately (provider session still active), masking the root cause.
The session-only storage was introduced in #11236 to avoid HTTP/2 header
size limits from large access_token/id_token JWTs (especially Azure
Entra ID with many group claims). The refresh token is a small opaque
string and does not contribute to that problem.
Move the refreshToken cookie out of the no-session fallback branch so it
is always set alongside the session storage. The refreshController
already has the fallback logic (req.session?.openidTokens?.refreshToken
|| parsedCookies.refreshToken) but previously never had a cookie to fall
back to.
Timeline before fix:
T=0 Login, session created (15 min maxAge), id_token valid ~1 hr
T=15min Session cookie expires, refresh token lost
T=15min+ Page refresh or id_token expiry triggers refresh, fails with
"Refresh token not provided", user redirected to /login
Timeline after fix:
T=0 Login, session created + refreshToken cookie (7 day expiry)
T=15min Session cookie expires
T=15min+ Refresh reads refreshToken from cookie fallback, succeeds,
restores session with fresh tokens
* fix(auth): pass scope parameter in OpenID refresh token grant
When using Azure Entra ID with a custom API scope (e.g., api://app-id/access_user)
and OPENID_REUSE_TOKENS=true, the refresh token exchange fails with AADSTS90009
because the scope parameter is not included in the refresh request.
Azure AD v2.0 requires the scope parameter when refreshing tokens issued for
custom API audiences. Without it, Azure interprets the request as the app
requesting a token for itself and rejects it.
This fix passes OPENID_SCOPE as the scope parameter to refreshTokenGrant(),
maintaining backward compatibility (no scope sent if OPENID_SCOPE is not set).
Fixes: refresh token 400 error with Azure custom API scopes
Tested: Azure Entra ID + Token Reuse + SharePoint integration

* 🐛 fix: Prevent deleted conversations from being recreated by async title generation
When a user deletes a chat while auto-generated title is still in progress,
`saveConvo` with `upsert: true` recreates the deleted conversation as a ghost
entry with only a title and no messages. This adds a `noUpsert` metadata option
to `saveConvo` and uses it in both agent and assistant title generation paths,
so the title save is skipped if the conversation no longer exists.
* test: conversation creation logic with noUpsert option
Added new tests to validate the behavior of the `saveConvo` function with the `noUpsert` option. This includes scenarios where a conversation should not be created if it doesn't exist, updating an existing conversation when `noUpsert` is true, and ensuring that upsert behavior remains the default when `noUpsert` is not provided. These changes improve the flexibility and reliability of conversation management.
* test: Clean up Conversation.spec.js by removing commented-out code
Removed unnecessary comments from the Conversation.spec.js test file to improve readability and maintainability. This includes comments related to database verification and temporary conversation handling, streamlining the test cases for better clarity.
* 🔧 refactor: Simplify MCP selection logic in useMCPSelect hook
- Removed redundant useEffect for setting ephemeral agent when MCP values change.
- Integrated ephemeral agent update directly into the MCP value change handler, improving code clarity and reducing unnecessary re-renders.
- Updated dependencies in the effect hook to ensure proper state management.
Why Effect 2 Was Added (PR #9528)
PR #9528 was a refactor that migrated MCP state from useLocalStorage hooks to Jotai atomWithStorage. Before that PR, useLocalStorage
handled bidirectional sync between localStorage and Recoil in one abstraction. After the migration, the two useEffect hooks were
introduced to bridge Jotai ↔ Recoil:
- Effect 1 (Recoil → Jotai): When ephemeralAgent.mcp changes externally, update the Jotai atom (which drives the UI dropdown)
- Effect 2 (Jotai → Recoil): When mcpValues changes, push it back to ephemeralAgent.mcp (which is read at submission time)
Effect 2 was needed because in that PR's design, setMCPValues only wrote to Jotai — it never touched Recoil. Effect 2 was the bridge to
propagate user selections into the ephemeral agent.
Why Removing It Is Correct
All user-initiated MCP changes go through setMCPValues. The callers are in useMCPServerManager: toggleServerSelection,
batchToggleServers, OAuth success callbacks, and access revocation. Our change puts the Recoil write directly in that callback, so all
these paths are covered.
All external changes go through Recoil, handled by Effect 1 (kept). Model spec application (applyModelSpecEphemeralAgent), agent
template application after submission, and BadgeRowContext initialization all write directly to ephemeralAgentByConvoId. Effect 1
watches ephemeralAgent?.mcp and syncs those into the Jotai atom for the UI.
There is no code path where mcpValues changes without going through setMCPValues or Effect 1. The only other source is
atomWithStorage's getOnInit reading from localStorage on mount — that's just restoring persisted state and is harmless (overwritten by
Effect 1 if the ephemeral agent has values).
Additional Benefits
- Eliminates the race condition. Effect 2 fired on mount with Jotai's stale default ([]), overwriting ephemeralAgent.mcp that had been
set by a model spec. Our change prevents that because the imperative sync only fires on explicit user action.
- Eliminates infinite loop risk. The old bidirectional two-effect approach relied on isEqual/JSON.stringify checks to break cycles. The
new unidirectional-reactive (Effect 1) + imperative (setMCPValues) approach has no such risk.
- Effect 1's enhancements are preserved. The mcp_clear sentinel handling and configuredServers filtering (both added after PR #9528)
continue to work correctly.
* ✨ feat: Add artifacts support to model specifications and ephemeral agents
- Introduced `artifacts` property in the model specification and ephemeral agent types, allowing for string or boolean values.
- Updated `applyModelSpecEphemeralAgent` to handle artifacts, defaulting to 'default' if true or an empty string if not specified.
- Enhanced localStorage handling to store artifacts alongside other agent properties, improving state management for ephemeral agents.
* 🔧 refactor: Update BadgeRowContext to improve localStorage handling
- Modified the logic to only apply values from localStorage that were actually stored, preventing unnecessary overrides of the ephemeral agent.
- Simplified the setting of ephemeral agent values by directly using initialValues, enhancing code clarity and maintainability.
* 🔧 refactor: Enhance ephemeral agent handling in BadgeRowContext and model spec application
- Updated BadgeRowContext to apply localStorage values only for tools not already set in ephemeralAgent, improving state management.
- Modified useApplyModelSpecEffects to reset the ephemeral agent when no spec is provided but specs are configured, ensuring localStorage defaults are applied correctly.
- Streamlined the logic for applying model spec properties, enhancing clarity and maintainability.
* refactor: Isolate spec and non-spec tool/MCP state with environment-keyed storage
Spec tool state (badges, MCP) and non-spec user preferences previously shared
conversation-keyed localStorage, causing cross-pollination when switching between
spec and non-spec models. This introduces environment-keyed storage so each
context maintains independent persisted state.
Key changes:
- Spec active: no localStorage persistence — admin config always applied fresh
- Non-spec (with specs configured): tool/MCP state persisted to __defaults__ key
- No specs configured: zero behavior change (conversation-keyed storage)
- Per-conversation isolation preserved for existing conversations
- Dual-write on user interaction updates both conversation and environment keys
- Remove mcp_clear sentinel in favor of null ephemeral agent reset
* refactor: Enhance ephemeral agent initialization and MCP handling in BadgeRowContext and useMCPSelect
- Updated BadgeRowContext to clarify the handling of localStorage values for ephemeral agents, ensuring proper initialization based on conversation state.
- Improved useMCPSelect tests to accurately reflect behavior when setting empty MCP values, ensuring the visual selection clears as expected.
- Introduced environment-keyed storage logic to maintain independent state for spec and non-spec contexts, enhancing user experience during context switching.
* test: Add comprehensive tests for useToolToggle and applyModelSpecEphemeralAgent hooks
- Introduced unit tests for the useToolToggle hook, covering dual-write behavior in non-spec mode and per-conversation isolation.
- Added tests for applyModelSpecEphemeralAgent, ensuring correct application of model specifications and user overrides from localStorage.
- Enhanced test coverage for ephemeral agent state management during conversation transitions, validating expected behaviors for both new and existing conversations.
- Updated the rendering logic in the Part component to handle whitespace-only text more effectively.
- Introduced a placeholder for whitespace-only last parts during streaming to enhance user experience.
- Ensured non-last whitespace-only parts are skipped to avoid rendering empty containers, improving layout stability.
Extract 7 standalone utilities from api/server/controllers/agents/client.js
into packages/api/src/agents/client.ts for TypeScript support and to
declutter the 1400-line controller module:

- Add endpointOption and endpointType to RequestBody type (packages/api/src/types/http.ts)
so payloadParser can access middleware-attached fields without type casts
- Add @typescript-eslint/no-unused-vars with underscore ignore patterns to the
packages/api eslint config block, matching the convention used by client/ and
data-provider/ blocks
- Update agent controller imports to consume the moved functions from @librechat/api
and remove now-unused direct imports (logAxiosError, labelContentByAgent,
getTokenCountForMessage)
* 🔧 refactor: Simplify payload parsing and enhance getSaveOptions logic
- Removed unused bedrockInputSchema from payloadParser, streamlining the function.
- Updated payloadParser to handle optional chaining for model parameters.
- Enhanced getSaveOptions to ensure runOptions defaults to an empty object if parsing fails, improving robustness.
- Adjusted the assignment of maxContextTokens to use the instance variable for consistency.

- Introduced comprehensive unit tests for the initializeAgent function, focusing on maxContextTokens behavior.
- Tests cover scenarios for user-defined values, fallback calculations, and edge cases such as zero and negative values, enhancing overall test coverage and reliability of agent initialization logic.
* refactor: default params Endpoint Configuration Handling
- Integrated `getEndpointsConfig` to fetch endpoint configurations, allowing for dynamic handling of `defaultParamsEndpoint`.
- Updated `buildEndpointOption` to pass `defaultParamsEndpoint` to `parseCompactConvo`, ensuring correct parameter handling based on endpoint type.
- Added comprehensive unit tests for `buildDefaultConvo` and `cleanupPreset` to validate behavior with `defaultParamsEndpoint`, covering various scenarios and edge cases.

- Updated multiple files to utilize the new function, enhancing code consistency and maintainability.
- Removed redundant logic for fetching `defaultParamsEndpoint`, simplifying the codebase.
- Introduced a new `EndpointMenuContent` component to lazily render endpoint submenu content, improving performance by deferring expensive model-list rendering until the submenu is mounted.
- Refactored `EndpointItem` to utilize the new component, simplifying the code and enhancing readability.
- Removed redundant filtering logic and model specifications handling from `EndpointItem`, centralizing it within `EndpointMenuContent` for better maintainability.
* 🔧 refactor: Implement tab-isolated storage for favorites and MCP selections
- Replaced `createStorageAtom` with `createTabIsolatedAtom` in favorites store to prevent cross-tab synchronization of favorites.
- Introduced `createTabIsolatedStorage` and `createTabIsolatedAtom` in `jotai-utils` to facilitate tab-specific state management.
- Updated MCP values atom family to utilize tab-isolated storage, ensuring independent MCP server selections across tabs.
* 🔧 fix: Update MCP selection logic to ensure active MCPs are only set when configured servers are available
- Modified the condition in `useMCPSelect` to check for both available MCPs and configured servers before setting MCP values. This change prevents potential issues when no servers are configured, enhancing the reliability of MCP selections.
* chore: Add Turborepo support and smart reinstall script
- Updated .gitignore to include Turborepo cache directory.
- Added Turbo as a dependency in package.json and package-lock.json.
- Introduced turbo.json configuration for build tasks.

- Fix Windows compatibility in hasTurbo() by checking for .cmd/.ps1 shims
- Remove Unix-specific shell syntax (> /dev/null 2>&1) from cache clearing
- Split try/catch blocks so daemon stop failure doesn't block cache clear
- Add actionable tips in error output pointing to --force and --verbose
* fix: Convert `const` to `enum` in MCP tool schemas for Gemini/Vertex AI compatibility
Gemini/Vertex AI rejects the JSON Schema `const` keyword in function declarations
with a 400 error. Previously, the Zod conversion layer accidentally stripped `const`,
but after migrating to pass raw JSON schemas directly to providers, the unsupported
keyword now reaches Gemini verbatim.
Add `normalizeJsonSchema` to recursively convert `const: X` → `enum: [X]`, which is
semantically equivalent per the JSON Schema spec and supported by all providers.
* fix: Update secure cookie handling in AuthService to use dynamic secure flag
Replaced the static `secure: isProduction` with a call to `shouldUseSecureCookie()` in the `setOpenIDAuthTokens` function. This change ensures that the secure cookie setting is evaluated at runtime, improving cookie handling in development environments while maintaining security in production.
* refactor: Simplify MCP tool key formatting and remove unused mocks in tests
- Updated MCP test suite to replace static tool key formatting with a dynamic delimiter from Constants, enhancing consistency and maintainability.
- Removed unused mock implementations for `@langchain/core/tools` and `@librechat/agents`, streamlining the test setup.
- Adjusted related test cases to reflect the new tool key format, ensuring all tests remain functional.
* chore: import order
- Introduced new model entries for 'moonshotai.kimi' and 'moonshotai.kimi-k2.5' in tokens.ts.
- Updated parameterSettings.ts to include configurations for MoonshotAI and ZAI providers.
- Enhanced schemas.ts by adding MoonshotAI and ZAI to the BedrockProviders enum for better integration.
* fix(openid): distinguish ID tokens from access tokens in federated auth

- AuthService.js: Added idToken field to session storage
- openIdJwtStrategy.js: Updated to read idToken from session
- openidStrategy.js: Explicitly included id_token in federatedTokens
- Test suites: Added comprehensive test coverage for token distinction

Fixed an issue where memory agents would fail with 'Provider Ollama not supported'
error when using Ollama as a custom endpoint. The getCustomEndpointConfig function
was only normalizing the endpoint config name but not the endpoint parameter
during comparison.
Changes:
- Modified getCustomEndpointConfig to normalize both sides of the endpoint comparison
- Added comprehensive test coverage for getCustomEndpointConfig including:
- Test for case-insensitive Ollama endpoint matching (main fix)
- Tests for various edge cases and error handling
This ensures that endpoint name matching works correctly for Ollama regardless
of case sensitivity in the configuration.
* 🔒 fix: Secure Cookie Localhost Bypass and OpenID Token Selection in AuthService
Two independent bugs in `api/server/services/AuthService.js` cause complete
authentication failure when using `OPENID_REUSE_TOKENS=true` with Microsoft
Entra ID (or Auth0) on `http://localhost` with `NODE_ENV=production`:
Bug 1: `secure: isProduction` prevents auth cookies on localhost
PR #11518 introduced `shouldUseSecureCookie()` in `socialLogins.js` to handle
the case where `NODE_ENV=production` but the server runs on `http://localhost`.
However, `AuthService.js` was not updated — it still used `secure: isProduction`
in 6 cookie locations across `setAuthTokens()` and `setOpenIDAuthTokens()`.
The `token_provider` cookie being dropped is critical: without it,
`requireJwtAuth` middleware defaults to the `jwt` strategy instead of
`openidJwt`, causing all authenticated requests to return 401.
Bug 2: `setOpenIDAuthTokens()` returns `access_token` instead of `id_token`
The `openIdJwtStrategy` validates the Bearer token via JWKS. For Entra ID
without `OPENID_AUDIENCE`, the `access_token` is a Microsoft Graph API token
(opaque or signed for a different audience), which fails JWKS validation.
The `id_token` is always a standard JWT signed by the IdP's JWKS keys with
the app's `client_id` as audience — which is what the strategy expects.
This is the same root cause as issue #8796 (Auth0 encrypted access tokens).
Changes:
- Consolidate `shouldUseSecureCookie()` into `packages/api/src/oauth/csrf.ts`
as a shared, typed utility exported from `@librechat/api`, replacing the
duplicate definitions in `AuthService.js` and `socialLogins.js`
- Move `isProduction` check inside the function body so it is evaluated at
call time rather than module load time
- Fix `packages/api/src/oauth/csrf.ts` which also used bare
`secure: isProduction` for CSRF and session cookies (same localhost bug)
- Return `tokenset.id_token || tokenset.access_token` from
`setOpenIDAuthTokens()` so JWKS validation works with standard OIDC
providers; falls back to `access_token` for backward compatibility
- Add 15 tests for `shouldUseSecureCookie()` covering production/dev modes,
localhost variants, edge cases, and a documented IPv6 bracket limitation
- Add 13 tests for `setOpenIDAuthTokens()` covering token selection,
session storage, cookie secure flag delegation, and edge cases
Refs: #8796, #11518, #11236, #9931
* chore: Adjust Import Order and Type Definitions in AgentPanel Component
- Reordered imports in `AgentPanel.tsx` for better organization and clarity.
- Updated type imports to ensure proper usage of `FieldNamesMarkedBoolean` and `TranslationKeys`.
- Removed redundant imports to streamline the codebase.
* 🐳 feat: Expose enableServiceLinks in Helm Deployment templates (#11740)
Allow users to disable Kubernetes service link injection via enableServiceLinks
in both LibreChat and RAG API Helm charts. This prevents pod startup failures
caused by "argument list too long" errors in namespaces with many services.
* Update helm/librechat/templates/deployment.yaml
* Update helm/librechat-rag-api/templates/rag-deployment.yaml

* fix: prevent truncated responses when Redis resumable streams are enabled
Race condition in RedisEventTransport.subscribe() caused early events
(seq 0+) to be lost. The Redis SUBSCRIBE command was fired as
fire-and-forget, but GenerationJobManager immediately set
hasSubscriber=true, disabling the earlyEventBuffer. Events published
during the gap between subscribe() returning and the Redis subscription
actually taking effect were neither buffered nor received — they were
silently dropped by Pub/Sub.
This manifested as "timeout waiting for seq 0, force-flushing N messages"
warnings followed by truncated or missing response text in the UI.
The fix:
- IEventTransport.subscribe() now returns an optional `ready` promise
that resolves once the transport can actually receive messages
- RedisEventTransport returns the Redis SUBSCRIBE acknowledgment as the
`ready` promise instead of firing it as fire-and-forget
- GenerationJobManager.subscribe() awaits `ready` before setting
hasSubscriber=true, keeping the earlyEventBuffer active during the
subscription window so no events are lost
- GenerationJobManager.emitChunk() early-returns after buffering when no
subscriber is connected, avoiding wasteful Redis PUBLISHes that nobody
would receive
Adds 5 regression tests covering the race condition for both in-memory
and Redis transports, verifying that events emitted before subscribe are
buffered and replayed, that the ready promise contract is correct for
both transport implementations, and that no events are lost across the
subscribe boundary.

## 7. TypeScript Conversion
## 7. Coding Standards
For detailed coding conventions, workspace boundaries, and architecture guidance, refer to the [`AGENTS.md`](../AGENTS.md) file at the project root. It covers code style, type safety, import ordering, iteration/performance expectations, frontend rules, testing, and development commands.
## 8. TypeScript Conversion
1. **Original State**: The project was initially developed entirely in JavaScript (JS).
2. **Frontend Transition**:
- We are in the process of transitioning the frontend from JS to TypeScript (TS).
- The transition is nearing completion.
- This conversion is feasible due to React's capability to intermix JS and TS prior to code compilation. It's standard practice to compile/bundle the code in such scenarios.
2. **Frontend**: Fully transitioned to TypeScript.
3. **Backend Considerations**:
- Transitioning the backend to TypeScript would be a more intricate process, especially for an established Express.js server.
3. **Backend**:
- The legacy Express.js server remains in `/api` as JavaScript.
- All new backend code is written in TypeScript under `/packages/api`, which is compiled and consumed by `/api`.
- Shared database logic lives in `/packages/data-schemas` (TypeScript).
- Shared frontend/backend API types and services live in `/packages/data-provider` (TypeScript).
- Minimize direct changes to `/api`; prefer adding TypeScript code to `/packages/api` and importing it.
- **Options for Transition**:
- **Single Phase Overhaul**: This involves converting the entire backend to TypeScript in one go. It's the most straightforward approach but can be disruptive, especially for larger codebases.
## 9. Module Import Conventions
- **Incremental Transition**: Convert parts of the backend progressively. This can be done by:
- Maintaining a separate directory for TypeScript files.
- Gradually migrating and testing individual modules or routes.
- Using a build tool like `tsc` to compile TypeScript files independently until the entire transition is complete.
Imports are organized into three sections (in order):
- **Compilation Considerations**:
- Introducing a compilation step for the server is an option. This would involve using tools like `ts-node` for development and `tsc` for production builds.
- However, this is not a conventional approach for Express.js servers and could introduce added complexity, especially in terms of build and deployment processes.
1. **Package imports** — sorted from shortest to longest line length.
- `react` is always the first import.
- Multi-line (stacked) imports count their total character length across all lines for sorting.
- **Current Stance**: At present, this backend transition is of lower priority and might not be pursued.
2. **`import type` imports** — sorted from longest to shortest line length.
- Package type imports come first, then local type imports.
- Line length sorting resets between the package and local sub-groups.
## 8. Module Import Conventions
3. **Local/project imports** — sorted from longest to shortest line length.
- Multi-line (stacked) imports count their total character length across all lines for sorting.
- Imports with alias `~` are treated the same as relative imports with respect to line length.
- `npm` packages first,
- from longest line (top) to shortest (bottom)
- Followed by typescript types (pertains to data-provider and client workspaces)
- longest line (top) to shortest (bottom)
- types from package come first
- Lastly, local imports
- longest line (top) to shortest (bottom)
- imports with alias `~` treated the same as relative import with respect to line length
- Consolidate value imports from the same module as much as possible.
- Always use standalone `import type { ... }` for type imports; never use inline `type` keyword inside value imports (e.g., `import { Foo, type Bar }` is wrong).
**Note:** ESLint will automatically enforce these import conventions when you run `npm run lint --fix` or through pre-commit hooks.

Please ensure that you adapt this summary to fit the specific context and nuances of your project.
For the full set of coding standards, see [`AGENTS.md`](../AGENTS.md).
The source code for `@librechat/agents` (major backend dependency, same team) is at `/home/danny/agentus`.
---
## Workspace Boundaries
- **All new backend code must be TypeScript** in `/packages/api`.
- Keep `/api` changes to the absolute minimum (thin JS wrappers calling into `/packages/api`).
- Database-specific shared logic goes in `/packages/data-schemas`.
- Frontend/backend shared API logic (endpoints, types, data-service) goes in `/packages/data-provider`.
- Build data-provider from project root: `npm run build:data-provider`.
---
## Code Style
### Structure and Clarity
- **Never-nesting**: early returns, flat code, minimal indentation. Break complex operations into well-named helpers.
- **Functional first**: pure functions, immutable data, `map`/`filter`/`reduce` over imperative loops. Only reach for OOP when it clearly improves domain modeling or state encapsulation.
- Reusable hooks / higher-order components for UI patterns.
- Parameterized helpers instead of near-duplicate functions.
- Constants for repeated values; configuration objects over duplicated init code.
- Shared validators, centralized error handling, single source of truth for business rules.
- Shared typing system with interfaces/types extending common base definitions.
- Abstraction layers for external API interactions.
### Iteration and Performance
- **Minimize looping** — especially over shared data structures like message arrays, which are iterated frequently throughout the codebase. Every additional pass adds up at scale.
- Consolidate sequential O(n) operations into a single pass whenever possible; never loop over the same collection twice if the work can be combined.
- Choose data structures that reduce the need to iterate (e.g., `Map`/`Set` for lookups instead of `Array.find`/`Array.includes`).
- Prevent memory leaks: careful with closures, dispose resources/event listeners, no circular references.
### Type Safety
- **Never use `any`**. Explicit types for all parameters, return values, and variables.
- **Limit `unknown`** — avoid `unknown`, `Record<string, unknown>`, and `as unknown as T` assertions. A `Record<string, unknown>` almost always signals a missing explicit type definition.
- **Don't duplicate types** — before defining a new type, check whether it already exists in the project (especially `packages/data-provider`). Reuse and extend existing types rather than creating redundant definitions.
- Use union types, generics, and interfaces appropriately.
- All TypeScript and ESLint warnings/errors must be addressed — do not leave unresolved diagnostics.
### Comments and Documentation
- Write self-documenting code; no inline comments narrating what code does.
- JSDoc only for complex/non-obvious logic or intellisense on public APIs.
- Single-line JSDoc for brief docs, multi-line for complex cases.
1. **Package imports** — sorted shortest to longest line length (`react` always first).
2. **`import type` imports** — sorted longest to shortest (package types first, then local types; length resets between sub-groups).
3. **Local/project imports** — sorted longest to shortest.
Multi-line imports count total character length across all lines. Consolidate value imports from the same module. Always use standalone `import type { ... }` — never inline `type` inside value imports.
### JS/TS Loop Preferences
- **Limit looping as much as possible.** Prefer single-pass transformations and avoid re-iterating the same data.
- `for (let i = 0; ...)` for performance-critical or index-dependent operations.
- `for...of` for simple array iteration.
- `for...in` only for object property enumeration.
---
## Frontend Rules (`client/src/**/*`)
### Localization
- All user-facing text must use `useLocalize()`.
- Only update English keys in `client/src/locales/en/translation.json` (other languages are automated externally).
- Semantic key prefixes: `com_ui_`, `com_assistants_`, etc.
### Components
- TypeScript for all React components with proper type imports.
- Semantic HTML with ARIA labels (`role`, `aria-label`) for accessibility.
- Group related components in feature directories (e.g., `SidePanel/Memories/`).
- Use `encodeURIComponent` for dynamic URL parameters.
### Performance
- Prioritize memory and speed efficiency at scale.
- Cursor pagination for large datasets.
- Proper dependency arrays to avoid unnecessary re-renders.
- Leverage React Query caching and background refetching.

## Development Commands
| Command | Purpose |
|---|---|
| `npm run smart-reinstall` | Install deps (if lockfile changed) + build via Turborepo |
| `npm run reinstall` | Clean install — wipe `node_modules` and reinstall from scratch |
| `npm run backend` | Start the backend server |
| `npm run backend:dev` | Start backend with file watching (development) |
| `npm run build` | Build all compiled code via Turborepo (parallel, cached) |
| `npm run frontend` | Build all compiled code sequentially (legacy fallback) |
| `npm run frontend:dev` | Start frontend dev server with HMR (port 3090, requires backend running) |
| `npm run build:data-provider` | Rebuild `packages/data-provider` after changes |
- Node.js: v20.19.0+ or ^22.12.0 or >= 23.0.0
- Database: MongoDB
- Backend runs on `http://localhost:3080/`; frontend dev server on `http://localhost:3090/`
---
## Testing
- Framework: **Jest**, run per-workspace.
- Run tests from their workspace directory: `cd api && npx jest <pattern>`, `cd packages/api && npx jest <pattern>`, etc.
- Frontend tests: `__tests__` directories alongside components; use `test/layout-test-utils` for rendering.
- Cover loading, success, and error states for UI/data flows.
### Philosophy
- **Real logic over mocks.** Exercise actual code paths with real dependencies. Mocking is a last resort.
- **Spies over mocks.** Assert that real functions are called with expected arguments and frequency without replacing underlying logic.
- **MongoDB**: use `mongodb-memory-server` for a real in-memory MongoDB instance. Test actual queries and schema validation, not mocked DB calls.
- **MCP**: use real `@modelcontextprotocol/sdk` exports for servers, transports, and tool definitions. Mirror real scenarios, don't stub SDK internals.
- Only mock what you cannot control: external HTTP APIs, rate-limited services, non-deterministic system calls.
- Heavy mocking is a code smell, not a testing strategy.

## Formatting
Fix all formatting lint errors (trailing spaces, tabs, newlines, indentation) using auto-fix when available. All TypeScript/ESLint warnings and errors **must** be resolved.
All notable changes to this project will be documented in this file.
