Implementation Reference

• src/gitlab_mcp/server.py:802-830 (handler)

  The `get_branch` tool handler function in `src/gitlab_mcp/server.py`. It fetches branch details using the GitLab client and formats the information for the user. Note that while `@mcp.tool()` is not immediately preceding this specific function in the file, it is part of the tool implementation set.
