GitLab MR MCP server

Let your AI read and comment on GitLab merge requests and issues for you.

Developer tools GitHub For it and development Version Control

This is a small helper that connects your AI assistant to GitLab, the place where your team stores code and reviews changes. Once it is set up, you can ask your AI to look at a merge request, read the discussion, or leave a comment, without clicking around the GitLab website yourself. It is handy for anyone who reviews code or keeps an eye on issues but does not want to hunt through pages.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to GitLab, so it can look up your projects, merge requests and issues, and even post comments for you. You just ask in plain words, and the helper does the clicking behind the scenes.

What this MCP server does

You ask your AI something like "show me the open merge requests in my project". The AI passes that request to this helper. The helper talks to GitLab using your access token and fetches the answer. Then the AI shows it back to you in the chat, as a list or a summary. If you ask it to comment or change a title, the helper makes that change in GitLab for you.

Flow diagram: you ask your AI “Show me the open merge requests in my project”, the GitLab MR MCP server connects it to GitLab, and you get back answers and updates in chat.

“What does issue 17 say?”

What it gives back to you

You get back plain answers in the chat: lists of projects or merge requests, the details of one merge request, its comments, or the code changes it contains. When you ask it to comment or change a title, it tells you the change was made. Everything arrives as text you can read right there, no need to open GitLab.
