Implementation Reference
- server.py:345-363 (handler)The handler function implementing the 'add_merge_request_comment' tool. It uses the GitLab client to retrieve the project and merge request, then creates a note (comment) on the merge request and returns its data. The @mcp.tool() decorator handles registration and schema inference from the signature and docstring.
