Troubleshooting

Common Issues

AI Tool Cannot Connect to Notion MCP

Symptoms: Connection timeout or failed errors, Notion MCP not appearing in tool directory, OAuth flow not starting

Cause: AI tool may not support MCP clients or remote MCP connections

Solution:

• Verify your AI tool supports MCP client functionality
• Check if tool supports remote MCP servers (HTTP/SSE transport)
• For tools without remote support, use STDIO with mcp-remote proxy: npx -y mcp-remote https://mcp.notion.com/mcp
• If tool lacks MCP support entirely, request feature from developers

OAuth Connection Fails

Symptoms: Authorization screen does not appear, Cannot complete OAuth flow, Connection succeeds but no workspace access

Cause: OAuth flow interrupted or workspace permissions issue

Solution:

• Use Notion app Settings > Connections > Notion MCP for easiest setup
• Ensure popup blockers are disabled during OAuth
• Check you have appropriate workspace permissions
• Try disconnecting and reconnecting through Notion app

Cannot Access Specific Pages or Databases

Symptoms: Some content returns not found errors, Searches return incomplete results, Database queries fail or return empty

Cause: Content access based on user permissions - AI tool can only see what you can see

Solution:

• Verify you have access to the pages/databases in Notion app
• Check workspace sharing settings for restricted content
• Ensure pages are not in private sections you cannot access
• Contact workspace admin if you need broader access

STDIO Transport Connection Issues

Symptoms: mcp-remote command fails, Connection drops frequently, Slow response times

Cause: STDIO transport requires mcp-remote proxy for hosted Notion MCP

Solution:

• Prefer Streamable HTTP or SSE transport if your tool supports it
• Ensure Node.js and npx are properly installed for STDIO
• Use config: npx -y mcp-remote https://mcp.notion.com/mcp
• Check network connectivity to mcp.notion.com

Tool Does Not Support Remote MCP Servers

Symptoms: Only local/STDIO servers work in tool, HTTP/SSE connections not available, No option to add remote server URL

Cause: Some MCP clients only support local STDIO servers

Solution:

• Use mcp-remote as proxy to convert HTTP to STDIO
• Configuration: command: npx, args: [-y, mcp-remote, https://mcp.notion.com/mcp]
• Alternative: Use open-source notion-mcp-server for local deployment
• Check tool documentation for remote server support roadmap

Command Not Found

Symptoms: mcpomni-connect: command not found, CLI not accessible

Cause: Package not installed or not in PATH

Solution:

• Verify installation: pip show mcpomni-connect
• Ensure Python scripts directory is in PATH
• Try running with python -m: python -m mcpomni_connect
• Reinstall: pip install --upgrade mcpomni-connect

Configuration File Not Found

Symptoms: FileNotFoundError: mcp_config.yaml, Config not loading

Cause: Config file missing or incorrect path

Solution:

• Verify config file exists at specified path
• Use absolute path: --config /full/path/to/mcp_config.yaml
• Check file name is exactly mcp_config.yaml (case-sensitive)
• Validate YAML syntax with yamllint or online validator

MCP Server Connection Failures

Symptoms: Server not responding, Connection timeout, Transport error

Cause: Invalid server configuration or transport issues

Solution:

• Verify transport type matches server capabilities (stdio, sse, http, docker, npx)
• For stdio: ensure command and args are correct
• For SSE/HTTP: verify URL is accessible and server is running
• For Docker: ensure Docker daemon is running and image exists
• Check environment variables are set (e.g., GITHUB_TOKEN)
• Test server manually outside MCPOmni-Connect

Agent Mode Not Working

Symptoms: Agent fails to execute task, Reasoning loop errors, Tool calls failing

Cause: Insufficient LLM configuration or tool access issues

Solution:

• Ensure LLM API key is configured (OpenAI, Anthropic, etc.)
• Verify agent has access to necessary MCP server tools
• Check task description is clear and actionable
• Review agent logs for detailed error messages
• Try simpler task first to verify agent functionality

Orchestrator Mode Failures

Symptoms: Plan execution fails, Step coordination errors, Agent communication issues

Cause: Invalid plan structure or agent dependencies

Solution:

• Verify plan steps are clearly defined and sequential
• Ensure each step can be completed with available tools
• Check inter-agent communication is working
• Review orchestrator logs for step-by-step execution details
• Test individual plan steps in agent mode first

Docker Transport Errors

Symptoms: Container not starting, Docker connection refused, Port binding errors

Cause: Docker configuration or runtime issues

Solution:

• Verify Docker is installed and running: docker ps
• Check Docker image exists: docker images
• Ensure ports are not already in use
• Review container logs: docker logs <container_name>
• Verify network configuration allows container communication

FastAPI Integration Issues

Symptoms: Import errors, Async execution failures, Endpoint not responding

Cause: Incorrect async configuration or FastAPI version mismatch

Solution:

• Use run_agent_async() for async FastAPI endpoints
• Ensure FastAPI version is compatible (0.100.0+)
• Verify MCPOmniClient is initialized outside request handlers
• Check async event loop configuration
• Review FastAPI logs for detailed error messages

Notion not appearing in MCPOmni-Connect

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check Notion installation
• Restart MCPOmni-Connect
• Check logs for error messages
