Expected Result: Relevant wiki pages containing authentication setup and API documentation
Retrieve Specific Wiki Page
Get content from a known wiki page path
Ask LibreChat: "Get the content from /docs/setup/installation.md"
Expected Result: Full content of the installation documentation page
Find Troubleshooting Guides
Search for problem-solving documentation
Ask LibreChat: "Find troubleshooting guides for deployment issues"
Expected Result: Wiki pages containing deployment troubleshooting information
Testing Your Setup
- Launch LibreChat
- Verify Azure Wiki Search is available in the tools list
- Test basic Azure Wiki Search functionality
Troubleshooting
Common Issues
Authentication Failed
Symptoms: Access denied to wiki, Unauthorized errors, PAT token rejected
Cause: Missing or invalid Azure DevOps Personal Access Token
Solution:
- Generate PAT in Azure DevOps with Wiki read permissions
- Set AZURE_DEVOPS_PAT environment variable
- Verify PAT has access to specified organization/project
- Check PAT expiration date
Organization/Project Not Found
Symptoms: Project not found errors, Organization does not exist
Cause: Invalid ORG or PROJECT configuration
Solution:
- Verify organization name matches Azure DevOps URL
- Confirm project exists and is accessible
- Check spelling and case sensitivity
- Use --org and --project parameters to override defaults
Wiki Content Not Found
Symptoms: No search results, Wiki path not found, Empty responses
Cause: Wiki not configured or content not available
Solution:
- Verify project has Wiki enabled
- Check wiki content exists in specified project
- Confirm search terms match available content
- Try broader search queries initially
uv Environment Issues
Symptoms: Command not found, Package installation fails, Virtual env errors
Cause: uv not installed or virtual environment not activated
Solution:
- Install uv: curl -LsSf https://astral.sh/uv/install.sh | sh
- Activate virtual environment before running
- Ensure Python 3.10+ is available
- Reinstall dependencies if corruption occurred
MCP Server Not Connecting
Symptoms: Status shows "Disconnected" or "Error", Server not appearing in list, Connection timeout
Cause: Invalid configuration, missing dependencies, or server startup failure
Solution:
- Check librechat.yaml syntax is valid YAML
- Verify npx and Node.js are available (for stdio/command-based servers)
- Check server command and args are correct
- Review LibreChat logs for error messages: docker logs librechat
- Increase timeout value if server takes longer to initialize
- Ensure required ports are not blocked (for HTTP-based servers)
OAuth Authentication Failing
Symptoms: Status shows "OAuth Required", Redirect loop during auth, Token refresh errors
Cause: OAuth credentials not configured or redirect URLs incorrect
Solution:
- Verify OAuth clientId and clientSecret in librechat.yaml
- Check redirect URL is correctly set in OAuth provider settings
- Ensure authorizationUrl and tokenUrl are accessible
- Complete OAuth flow by clicking "Initialize" in MCP Settings panel
- Check browser console for OAuth-related errors
User Credentials Not Working
Symptoms: Prompts for credentials not appearing, Variables not substituted, Authentication errors
Cause: User credential variables incorrectly formatted or not entered
Solution:
- Use correct format: {{USER_VARIABLE_NAME}} in librechat.yaml
- Enter credentials through MCP Settings panel in UI
- Verify variable names match between config and UI
- Check credentials are saved per-user (not shared globally)
Tools Not Appearing in Chat
Symptoms: No tool dropdown available, MCP tools missing from interface, Server connected but tools unavailable
Cause: MCP server not properly integrated with chat endpoint or agent
Solution:
- Verify you are using an endpoint that supports MCP (not all models do)
- Check if Agent Builder is enabled and MCP tools are assigned to agent
- Restart chat session after adding new MCP servers
- Verify MCP server actually provides tools (some servers are resource-only)
- Check server logs to confirm tools are being discovered
Docker Deployment Problems
Symptoms: Container fails to start, Database connection errors, Port conflicts
Cause: Docker configuration issues or missing environment variables
Solution:
- Verify .env file is properly configured with all required variables
- Check MongoDB connection string is correct
- Ensure ports 3080 (frontend) and 3081 (backend) are available
- Run docker compose logs to view detailed error messages
- Verify Docker and Docker Compose versions meet minimum requirements
Performance Issues with MCP
Symptoms: Slow tool execution, Timeout errors, UI freezing during tool calls
Cause: Server timeout too short, inefficient MCP server, or network latency
Solution:
- Increase timeout values in librechat.yaml (both init and operation timeouts)
- Use HTTP transport instead of stdio for remote servers
- Monitor MCP server performance independently
- Consider caching for frequently accessed resources
- Use Streamable HTTP transport for production environments
Azure Wiki Search not appearing in LibreChat
Symptoms: Server not listed, Tools not available
Cause: Configuration or installation issue
Solution:
- Verify configuration syntax
- Check Azure Wiki Search installation
- Restart LibreChat
- Check logs for error messages
