Get a second pair of eyes on your code without waiting for a teammate
Paste an MR link, get instant feedback on your changes, and catch issues before your code review even starts
Overview
You finish a feature, push the MR, scroll through your own diff. It looks fine, but you are not sure. Maybe you are missing something. You could wait for a teammate to review, but that takes time and you would rather not waste their cycles on obvious issues. You just want to paste a link and get a gut check.
How it works
MCP connects to GitLab and pulls the merge request diff directly. You paste the MR link and ask for a review. The AI scans the changes and flags potential issues: logic errors, missing edge cases, style inconsistencies, things you might have overlooked. You discuss anything it finds, make changes if needed, then run the review again. When you are confident, you send it to your team for human review.
Who this is for
Engineers who want a quick sanity check on their code before sending it to teammates. Especially useful for solo developers, small teams, or when you want to clean up obvious issues before your PR gets human eyes on it.
Suggested prompt
Help me review code before I send it to my team. Start by asking me for: (1) the link to the merge request, (2) any specific areas I am unsure about or want you to focus on, and (3) context about what this MR is trying to accomplish. Once you have my answers, pull the MR from GitLab and review the diff. Flag anything that looks off: logic issues, edge cases, style problems, or things that might confuse a reviewer. Walk me through what you found. If I make changes and push again, I will ask you to re-review.
Frequently asked questions
Do I need to check out the branch locally?
No. MCP pulls the merge request diff directly from GitLab. You paste the MR link, the AI reads the changes, and gives you feedback without needing the code on your machine.
What kind of issues does it catch?
It flags logic errors, missing edge cases, style inconsistencies, and things that might confuse a human reviewer. It is not a replacement for a teammate review, but it catches the obvious stuff before you send it over.
Can I re-run the review after making changes?
Yes. Push your changes and ask for another review. The AI pulls the updated diff and checks whether the issues it flagged have been addressed, plus scans for anything new.
Does it work with GitHub or just GitLab?
This template is set up for GitLab. The approach works the same with GitHub if you swap the integration when setting up your server.
