- Bump version of @modelcontextprotocol/sdk to 1.12.3 to incorporate recent updates.
- Update dependencies for ajv and cross-spawn to their latest versions.
- Add ajv as a new dependency in the sdk module.
- Include json-schema-traverse as a new dependency in the sdk module.

* feat: @librechat/auth

* feat: Add crypto module exports to auth package

- Introduced a new crypto module by creating index.ts in the crypto directory.
- Updated the main index.ts of the auth package to export from the new crypto module.

* feat: Update package dependencies and build scripts for auth package

- Added @librechat/auth as a dependency in package.json and package-lock.json.
- Updated build scripts to include the auth package in both frontend and bun build processes.
- Removed unused mongoose and openid-client dependencies from package-lock.json for cleaner dependency management.

* refactor: Migrate crypto utility functions to @librechat/auth

- Replaced local crypto utility imports with the new @librechat/auth package across multiple files.
- Removed the obsolete crypto.js file and its exports.
- Updated relevant services and models to utilize the new encryption and decryption methods from @librechat/auth.

* feat: Enhance OAuth token handling and update dependencies in auth package

* chore: Remove Token model and TokenService due to restructuring of OAuth handling

- Deleted the Token.js model and TokenService.js, which were responsible for managing OAuth tokens.
- This change is part of a broader refactor to streamline OAuth token management and improve code organization.

* refactor: imports from '@librechat/auth' to '@librechat/api' and add OAuth token handling functionality

* refactor: Simplify logger usage in MCP and FlowStateManager classes

* chore: fix imports

* feat: Add OAuth configuration schema to MCP with token exchange method support

* feat: FIRST PASS Implement MCP OAuth flow with token management and error handling

- Added a new route for handling OAuth callbacks and token retrieval.
- Integrated OAuth token storage and retrieval mechanisms.
- Enhanced MCP connection to support automatic OAuth flow initiation on 401 errors.
- Implemented dynamic client registration and metadata discovery for OAuth.
- Updated MCPManager to manage OAuth tokens and handle authentication requirements.
- Introduced comprehensive logging for OAuth processes and error handling.

* refactor: Update MCPConnection and MCPManager to utilize new URL handling

- Added a `url` property to MCPConnection for better URL management.
- Refactored MCPManager to use the new `url` property instead of a deprecated method for OAuth handling.
- Changed logging from info to debug level for flow manager and token methods initialization.
- Improved comments for clarity on existing tokens and OAuth event listener setup.

* refactor: Improve connection timeout error messages in MCPConnection and MCPManager and use initTimeout for connection

- Updated the connection timeout error messages to include the duration of the timeout.
- Introduced a configurable `connectTimeout` variable in both MCPConnection and MCPManager for better flexibility.

* chore: cleanup MCP OAuth Token exchange handling; fix: erroneous use of flowsCache and remove verbose logs

* refactor: Update MCPManager and MCPTokenStorage to use TokenMethods for token management

- Removed direct token storage handling in MCPManager and replaced it with TokenMethods for better abstraction.
- Refactored MCPTokenStorage methods to accept parameters for token operations, enhancing flexibility and readability.
- Improved logging messages related to token persistence and retrieval processes.

* refactor: Update MCP OAuth handling to use static methods and improve flow management

- Refactored MCPOAuthHandler to utilize static methods for initiating and completing OAuth flows, enhancing clarity and reducing instance dependencies.
- Updated MCPManager to pass flowManager explicitly to OAuth handling methods, improving flexibility in flow state management.
- Enhanced comments and logging for better understanding of OAuth processes and flow state retrieval.

* refactor: Integrate token methods into createMCPTool for enhanced token management

* refactor: Change logging from info to debug level in MCPOAuthHandler for improved log management

* chore: clean up logging

* feat: first pass, auth URL from MCP OAuth flow

* chore: Improve logging format for OAuth authentication URL display

* chore: cleanup mcp manager comments

* feat: add connection reconnection logic in MCPManager

* refactor: reorganize token storage handling in MCP

- Moved token storage logic from MCPManager to a new MCPTokenStorage class for better separation of concerns.
- Updated imports to reflect the new token storage structure.
- Enhanced methods for storing, retrieving, updating, and deleting OAuth tokens, improving overall token management.

* chore: update comment for SYSTEM_USER_ID in MCPManager for clarity

* feat: implement refresh token functionality in MCP

- Added refresh token handling in MCPManager to support token renewal for both app-level and user-specific connections.
- Introduced a refreshTokens function to facilitate token refresh logic.
- Enhanced MCPTokenStorage to manage client information and refresh token processes.
- Updated logging for better traceability during token operations.

* chore: cleanup @librechat/auth

* feat: implement MCP server initialization in a separate service

- Added a new service to handle the initialization of MCP servers, improving code organization and readability.
- Refactored the server startup logic to utilize the new initializeMCP function.
- Removed redundant MCP initialization code from the main server file.

* fix: don't log auth url for user connections

* feat: enhance OAuth flow with success and error handling components

- Updated OAuth callback routes to redirect to new success and error pages instead of sending status messages.
- Introduced `OAuthSuccess` and `OAuthError` components to provide user feedback during authentication.
- Added localization support for success and error messages in the translation files.
- Implemented countdown functionality in the success component for a better user experience.

* fix: refresh token handling for user connections, add missing URL and methods

- add standard enum for system user id and helper for determining app-lvel vs. user-level connections

* refactor: update token handling in MCPManager and MCPTokenStorage

* fix: improve error logging in OAuth authentication handler

* fix: concurrency issues for both login url emission and concurrency of oauth flows for shared flows (same user, same server, multiple calls for same server)

* fix: properly fail shared flows for concurrent server calls and prevent duplication of tokens

* chore: remove unused auth package directory from update configuration

* ci: fix mocks in samlStrategy tests

* ci: add mcpConfig to AppService test setup

* chore: remove obsolete MCP OAuth implementation documentation

* fix: update build script for API to use correct command

* chore: bump version of @librechat/api to 1.2.4

* fix: update abort signal handling in createMCPTool function

* fix: add optional clientInfo parameter to refreshTokensFunction metadata

* refactor: replace app.locals.availableTools with getCachedTools in multiple services and controllers for improved tool management

* fix: concurrent refresh token handling issue

* refactor: add signal parameter to getUserConnection method for improved abort handling

* chore: JSDoc typing for `loadEphemeralAgent`

* refactor: update isConnectionActive method to use destructured parameters for improved readability

* feat: implement caching for MCP tools to handle app-level disconnects for loading list of tools

* ci: fix agent test
