Implementation Reference

• gitlab_clone_mcp_server/server.py:556-568 (handler)

  The tool handler for 'get_current_user'. Calls GitLab API /user endpoint to get the authenticated user's info and returns name, username, email, and ID.

  @mcp.tool()
  async def get_current_user(token: str = None, ctx=None) -> str:
