Implementation Reference

src/handlers/merge-requests.ts:523-539 (handler)

The main handler function that executes the tool logic by sending a PUT request to the GitLab API to update the body of a specific note in a merge request discussion.

async updateMRDiscussionNote(args: UpdateMRDiscussionNoteParams) {
  const data = await this.client.put(
    `/projects/${encodeURIComponent(args.project_id)}/merge_requests/${
      args.merge_request_iid
    }/discussions/${args.discussion_id}/notes/${args.note_id}`,
    { body: args.body }
  );

  return {
    content: [
      {
        type: "text",
        text: JSON.stringify(data, null, 2),
      },
    ],
  };
}
