Implementation Reference

• src/gitlab_mcp/server.py:421-444 (handler)

  The MCP tool handler for 'get_merge_request_commits', which calls the GitLab client's method.

      """取得 Merge Request 包含的 commits

          client = get_client()
          commits = client.get_merge_request_commits(project_id, mr_iid)

              return "此 MR 沒有 commits"

• src/gitlab_mcp/gitlab_client.py:262-267 (handler)

  The actual implementation of get_merge_request_commits which communicates with the GitLab API.

  def get_merge_request_commits(
      self, project_id: int | str, mr_iid: int
  ) -> list[dict]:
      """GET /projects/:id/merge_requests/:iid/commits"""
      pid = self._resolve_project_id(project_id)
      return self._get_json(f"/projects/{pid}/merge_requests/{mr_iid}/commits")
