Implementation Reference

• server.py:429-451 (handler)

  The @mcp.tool() decorated handler function that implements the resolve_merge_request_discussion tool. It fetches the GitLab project and merge request, gets the specific discussion, sets its resolved state, saves it, and returns the updated discussion as a dictionary.

  @mcp.tool()
  def resolve_merge_request_discussion(ctx: Context, project_id: str, merge_request_iid: str, discussion_id: str, resolved: bool = True) -> Dict[str, Any]:
