Provides tools for reviewing GitLab merge requests via the REST API: fetch merge request metadata and diff_refs SHAs, list changed files with raw diffs, and post inline comments on specific lines of a merge request's diff. Renamed files are resolved automatically, and line numbers refer to lines visible in the MR diff.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mcp-http-gitlab review MR !42 in my-group/my-repo and comment on line 15 of src/main.ts"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
