Troubleshooting
Common Issues
Import Error - Module Not Found
Symptoms: ModuleNotFoundError: No module named mcp_agent, Import fails
Cause: mcp-agent not installed or wrong Python environment
Solution:
- Verify installation: pip show mcp-agent
- Ensure using correct Python environment/virtualenv
- Reinstall: pip install --upgrade mcp-agent
- Check Python version is 3.9 or higher
MCP Server Connection Failures
Symptoms: Server not starting, Connection timeout, Tool execution errors
Cause: Invalid MCP server configuration or missing dependencies
Solution:
- Verify npx is installed and accessible (required for stdio servers)
- Check MCP server package name and arguments are correct
- Test server independently: npx -y @modelcontextprotocol/server-filesystem /path
- Review agent logs for detailed error messages
- Ensure required environment variables are set
LLM API Authentication Errors
Symptoms: 401 Unauthorized, API key invalid, Provider authentication failed
Cause: Missing or incorrect API keys for LLM provider
Solution:
- Set environment variables: ANTHROPIC_API_KEY, OPENAI_API_KEY, etc.
- Verify API key is valid and has correct permissions
- Check API key format matches provider requirements
- Pass api_key parameter explicitly in Agent initialization
Workflow Execution Failures
Symptoms: Workflow hangs, Timeout errors, Incomplete results
Cause: Workflow pattern misconfiguration or task complexity
Solution:
- Increase timeout values for long-running tasks
- Break complex workflows into smaller steps
- Verify all workflow dependencies are available
- Check Temporal backend is running (for production deployments)
- Review workflow logs for specific error messages
Temporal Backend Connection Issues
Symptoms: Cannot connect to Temporal, Workflow registration fails, Worker errors
Cause: Temporal server not running or misconfigured
Solution:
- Verify Temporal server is running: temporal server health
- Check Temporal connection settings (host, port, namespace)
- Ensure Temporal workers are registered correctly
- Review Temporal server logs for connection errors
- Start local Temporal dev server: temporal server start-dev
Performance Issues with Large Workflows
Symptoms: Slow execution, High memory usage, Timeout errors
Cause: Inefficient workflow design or resource constraints
Solution:
- Use map-reduce pattern for parallelizable tasks
- Implement batching for large data processing
- Enable Temporal backend for better resource management
- Monitor agent memory usage and optimize task size
- Consider streaming responses for large outputs
Alibaba Cloud AnalyticDB for PostgreSQL not appearing in mcp-agent
Symptoms: Server not listed, Tools not available
Cause: Configuration or installation issue
Solution:
- Verify configuration syntax
- Check Alibaba Cloud AnalyticDB for PostgreSQL installation
- Restart mcp-agent
- Check logs for error messages
