What Comfy MCP does
The line above is not decoration and not a comment for readers: it is the ownership token the official MCP Registry checks. Publishing the listing in server.json makes registry.modelcontextprotocol.io fetch this package's metadata from PyPI and look for mcp-name: in the description — which for this project is this file, verbatim, as [project] readme in pyproject.toml. Finding it is how the registry proves that whoever owns the GitHub namespace also owns the PyPI package.
