Lets your AI check code for made-up packages, old APIs and other AI mistakes, right inside your chat.

Developer tools Coding For it and development Developer Tools

Open Code Review is a free tool that checks code for a special kind of mistake: the ones AI assistants make when they write code. It looks for packages that do not exist, APIs that are out of date, and other odd things. The MCP server is the part that plugs this checker into your AI chat, so you can ask your AI to review code and get an answer without leaving the conversation.

What is an MCP server? The 30-second version

On its own, your AI can only chat. It cannot run a checker on your code or look up whether a package really exists. An MCP server is a small helper program that gives your AI a new skill. This one connects your AI to Open Code Review, so when you ask it to check your code, it can actually run the scan and tell you what it found.

What this MCP server does

You ask your AI to review some code. Your AI passes that request to this helper, which runs the Open Code Review scanner on the files. The scanner checks for things like imports of packages that do not exist, old APIs, and security patterns. Then the results come back to your AI, and your AI explains them to you in the chat.

Flow diagram: you ask your AI “Check my code for made up packages and old APIs”, the Open Code Review MCP server works in steps: reads your code, then checks each line, then scores the results, and you get back A list of issues and a score.

Try asking your AI

“Can you scan my src folder and tell me what is wrong?”
“Check this file for made-up packages and old APIs.”
“Explain the issues in my last scan in simple words.”
“Suggest fixes for the problems you found.”

What it gives back to you

You get back a list of issues, each with a short description and a severity level. You also get an overall score, like 67 out of 100, and a pass or fail result. Your AI can then explain any issue in plain words or suggest a fix.

Before you start

What you need

Node.js installed on your computer (the free program that runs npx commands)
The Claude desktop app or another AI tool that supports MCP servers
Optional: Ollama if you want the AI part to run fully on your own machine

Good to know

The heal tool can change your files, so review the suggested fixes before applying them.

Install it with your AI
