+```env +# At least one API key is required +GEMINI_API_KEY=your_gemini_key +OPENAI_API_KEY=your_openai_key +# ... other keys +``` + +**Troubleshooting:** +- If Option 1 fails: check that the Docker image exists (`docker images zen-mcp-server`). +- If Option 2 fails: verify the compose file path and ensure the service is not already in use. +- Permission issues: make sure the `logs` folder is
