ReviewGate MCP server

ReviewGate is a free tool that reviews code changes against the rules your team actually wrote down, like your conventions and decision notes. It runs in your editor, before you push, and again on the pull request. It is handy if you write code and want your AI helper to catch rule breaks before a human reviewer does.

What this MCP server does

You ask your AI to review the code you just changed. The AI calls this helper, which runs ReviewGate on those changes. ReviewGate first has a quick pass look for problems, then a second, stronger pass tries to disprove each one against the actual code. Only the findings that survive both passes come back. Your AI then shows you the list, with the rule each finding points to.

What you can do with it

• Check your uncommitted changes against your team's rules
• Fetch the rules your team wrote so the AI knows what to check
• Review staged, uncommitted, or already committed changes
• Catch rule breaks before you push your branch
• Get a short list of findings instead of a wall of noise
• See which of your written rules each finding refers to

Try asking your AI

• “Review my staged changes against our team rules”
• “What rules does our project have written down?”
• “Check my last commit and tell me if it breaks any of our conventions”
• “Look at the changes on this branch and list any problems”

What it gives back to you

You get back a list of findings, each one pointing at a spot in your code and quoting the rule it breaks. Your AI shows this in the chat as a short summary with the details underneath. If nothing is wrong, you get a clean result. You can then fix things before you push.

Before you start

Who it's for

Developers and small teams who already write down their coding rules and want an AI to check changes against them.
