Instructions

Implementation Reference

• src/gitlab_mcp/server.py:362-375 (handler)

  The MCP tool handler that receives the request and calls the GitLab client to approve a merge request.

  def approve_merge_request(project_id: int | str, mr_iid: int) -> str:
      """核准 Merge Request
  
      Args:
          project_id: 專案 ID 或路徑
          mr_iid: MR 的 IID
      """
      try:
          client = get_client()
          client.approve_merge_request(project_id, mr_iid)
          return f"✓ MR !{mr_iid} 已核准"
      except GitLabAPIError as e:
          return f"核准 MR 失敗: {str(e)}"

• src/gitlab_mcp/gitlab_client.py:252-255 (handler)

  The underlying API client method that performs the actual HTTP POST request to GitLab to approve a merge request.

  def approve_merge_request(self, project_id: int | str, mr_iid: int) -> dict:
      """POST /projects/:id/merge_requests/:iid/approve"""
      pid = self._resolve_project_id(project_id)
      return self._post_json(f"/projects/{pid}/merge_requests/{mr_iid}/approve")
