Lets Claude, Cursor and other assistants run Knip on your JavaScript or TypeScript project and read back unused files, exports and dependencies.

This is the Knip project's own MCP server, published as the @knip/mcp package. It runs the same unused-code checks as the knip CLI, in your project folder, with no account or network calls. It is a good fit for an assistant doing a cleanup pass, since it also returns hints when Knip is not configured yet, so the assistant can suggest a starting configuration.

Good for

  • Developers who want an assistant to clean up dead code and unused dependencies
  • Teams setting up Knip for the first time and wanting configuration suggestions

Low risk

It reads your project's files to find unused code and reports the results; it does not change or delete anything itself.

What it can do

Watch out for

  • It only reads your project

    Knip itself does not delete files; it reports what is unused so you or the assistant can decide what to remove. github.com

Questions

Is this official?

Yes. It is Knip's own MCP server package.

Does it need an API key?

No. It runs locally against your project files.

Does it delete the unused code it finds?

No. It only reports unused files, exports and dependencies. Removing them is up to you or a separate Knip CLI run with --fix.

Is it free?

Yes, open source with no limits documented.

Can I use it from VS Code?

Yes. The Knip VS Code extension bundles this MCP server, or you can add it directly as shown in the install box.

How do I add it to Claude Code?

Run claude mcp add knip -- npx -y @knip/mcp in your project. It needs Node.js; the Claude Code tab above shows the same command and the config-file form.
