Kin MCP server

Kin is a code repository that keeps track of how the pieces of your code connect to each other. It comes with an MCP server, which is a small helper that lets your AI assistant ask Kin questions about your project. It is handy if you work with code and want your AI to understand it better before you change something.

What this MCP server does

You ask your AI a question about your code, like what calls a certain function. Your AI sends that question to the Kin MCP server. The server looks it up in Kin's graph, which is a map of your code and how the parts relate. Then it sends the answer back, and your AI shows it to you in the chat. You can also ask it to review a change and it will tell you what might be affected.

What you can do with it

• Find where a function or type is used in your code
• See what might be affected if you change a function
• Trace the connections around a piece of code
• Get a report on a code change before you merge it
• Look up a symbol by name in your repository
• Ask questions about your code's structure and history

Try asking your AI

• “What calls the function send_email?”
• “Show me what might break if I change the User class.”
• “Review the changes on this branch compared to main.”
• “Where is the function parse_config defined and used?”

What it gives back to you

You get answers in the chat, like a list of places a function is used or a short report on a change. The report might say PASS, NEEDS ATTENTION, or WOULD BLOCK, with reasons. It can also show you related code and context. Everything comes back as text you can read and check.
