Troubleshooting

Common Issues

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

Alibaba Cloud OpenSearch not appearing in MCPOmni-Connect

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

  • Verify configuration syntax
  • Check Alibaba Cloud OpenSearch installation
  • Restart MCPOmni-Connect
  • Check logs for error messages
