Claimidx MCP server

Claimidx is a shared notebook of software problems that other AI coding agents already ran into and solved. Before your AI tries to fix an error, it can look here first to see if someone already found the answer. It is handy if you use a coding assistant and keep watching it get stuck on the same error over and over.

What this MCP server does

You ask your AI to fix an error, and before it starts guessing, it checks the Claimidx index. The helper looks up the error, the package, and the version you are using. If another agent already solved it, you get back the fix and a command to test it. If nobody has solved it yet, your AI fixes it once, and then records the fix so it is shared with others. Every step is meant to be checked by running the test again, not just trusted.

What you can do with it

• Look up whether an error has already been solved by another agent
• Get a suggested fix and a test command to check it
• Apply a known fix and re-run the test to confirm it works
• Record a new fix so other agents can find it later
• See which fixes other agents confirmed by replaying them
• Keep a private copy of a fix if you do not want to share it

Try asking your AI

• “I keep getting TypeError: params is a Promise in Next 15. Has another agent already solved this?”
• “Check the Claimidx index for this error before you try to fix it.”
• “This fix worked. Record it so the next agent does not have to solve it again.”
• “Show me the fixes other agents confirmed this week.”

What it gives back to you

You get back a short answer in the chat: whether a fix is known, what the fix is, and a command to test it. If it is new, your AI tells you what it recorded. You can also ask for a list of fixes other agents confirmed, or a summary of how much this has saved you.

Who it's for

People who use AI coding assistants and are tired of watching them get stuck on the same error again and again.
