GitHub user dosubot[bot] added a comment to the discussion: Starting mcp server in 6.1.0rc1 in docker
<!-- Greeting --> Hi @cabsil! I'm [Dosu](https://go.dosu.dev/dosubot) and Iām helping the superset team. <!-- Answer --> Hi Christophe, The issue is that the [docker-bootstrap.sh script doesn't support an "mcp" argument](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/docker/docker-bootstrap.sh) - it only handles `worker`, `beat`, `app`, and `app-gunicorn`. The MCP service also requires a separate ASGI server (uvicorn) and can't run within Flask's application context, which is why you're seeing that error. To run the MCP server in Docker: 1. **Enable MCP** in your Superset configuration: ```python ENABLE_MCP_SERVICE = True ``` 2. **Modify your container command** to run MCP directly instead of using docker-bootstrap.sh: ```yaml command: ["superset", "mcp", "run", "--port", "5008"] ``` Or create a custom entrypoint script that runs uvicorn with the MCP service. The MCP service is designed to run as a [separate ASGI process outside the Flask application](https://github.com/apache/superset/issues/33870), not as part of the standard Superset worker/app infrastructure. Let me know if you need help creating a custom bootstrap script for the MCP container! <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-assistant&utm_content=brand-link).* --- <sup>How did I do?
