* feat: Implement reconnection staggering and backoff jitter for MCP connections
- Enhanced the reconnection logic in OAuthReconnectionManager to stagger reconnection attempts for multiple servers, reducing the risk of connection storms.
- Introduced a backoff delay with random jitter in MCPConnection to improve reconnection behavior during network issues.
- Updated the ConnectionsRepository to handle multiple server connections concurrently with a defined concurrency limit.
Added tests to ensure the new reconnection strategy works as intended.
* refactor: Update MCP server query configuration for improved data freshness
- Reduced stale time from 5 minutes to 30 seconds to ensure quicker updates on server initialization.
- Enabled refetching on window focus and mount to enhance data accuracy during user interactions.
* ♻️ refactor: On-demand MCP connections; remove proactive reconnection, default to available
- Remove reconnectServers() from refresh controller (connection storm root cause)
- Stop gating server selection on connection status; add to selection immediately
- Render agent panel tools from DB cache, not live connection status
- Proceed to cached tools on init failure (only gate on OAuth)
- Remove unused batchToggleServers()
- Reduce useMCPServersQuery staleTime from 5min to 30s, enable refetchOnMount/WindowFocus
* refactor: Optimize MCP tool initialization and server connection logic
- Adjusted tool initialization to only occur if no cached tools are available, improving efficiency.
- Updated comments for clarity on server connection and tool fetching processes.
- Removed unnecessary connection status checks during server selection to streamline the user experience.
* Feature: Dynamic MCP Server with Full UI Management
* 🚦 feat: Add MCP Connection Status icons to MCPBuilder panel (#10805)

* fix: address code review feedback for MCP server management
- Fix OAuth secret preservation to avoid mutating input parameter
by creating a merged config copy in ServerConfigsDB.update()
- Improve error handling in getResourcePermissionsMap to propagate
critical errors instead of silently returning empty Map
- Extract duplicated MCP server filter logic by exposing selectableServers
from useMCPServerManager hook and using it in MCPSelect component
* test: Update PermissionService tests to throw errors on invalid resource types
- Changed the test for handling invalid resource types to ensure it throws an error instead of returning an empty permissions map.
- Updated the expectation to check for the specific error message when an invalid resource type is provided.
* feat: Implement retry logic for MCP server creation to handle race conditions
- Enhanced the createMCPServer method to include retry logic with exponential backoff for handling duplicate key errors during concurrent server creation.
- Updated tests to verify that all concurrent requests succeed and that unique server names are generated.
- Added a helper function to identify MongoDB duplicate key errors, improving error handling during server creation.
* refactor: StatusIcon to use CircleCheck for connected status
- Replaced the PlugZap icon with CircleCheck in the ConnectedStatusIcon component to better represent the connected state.
- Ensured consistent icon usage across the component for improved visual clarity.
* test: Update AccessControlService tests to throw errors on invalid resource types
- Modified the test for invalid resource types to ensure it throws an error with a specific message instead of returning an empty permissions map.
- This change enhances error handling and improves test coverage for the AccessControlService.
* fix: Update error message for missing server name in MCP server retrieval
- Changed the error message returned when the server name is not provided from 'MCP ID is required' to 'Server name is required' for better clarity and accuracy in the API response.
