get_merge_requests

Instructions

Args:

    ctx: MCP context (automatically injected)

Implementation Reference

• gitlab_clone_mcp_server/server.py:146-169 (handler)

  The get_merge_requests tool handler function. It calls the GitLab API /projects/{id}/merge_requests endpoint with an optional state filter (opened, closed, merged, all), limits results to 10 MRs, and returns formatted output with IID, title, state, and author.

  @mcp.tool()
  async def get_merge_requests(project_id: int, state: str = "opened", token: str = None, ctx=None) -> str:
      """Get merge requests for a GitLab project.

  The get_merge_requests function is registered as an MCP tool via the @mcp.tool() decorator from FastMCP.

• gitlab_clone_mcp_server/server.py:11-52 (helper)

  The make_gitlab_request helper function handles all GitLab API calls. It manages token priority (explicit > context headers > env var), constructs the URL with the GitLab base URL, and performs HTTP requests with httpx.
