What you can do with it

  • Search and read a product's published help pages from inside Claude, Cursor or ChatGPT
  • Search past customer conversations to see how support questions were handled
  • Ask a question and get an answer with cited sources, or start an investigation into the product's code

Make money with it

""

An idea, not financial advice. Check the licence before charging for anything built on it.

Ways a business could use it

  • Let support staff query help pages and past conversations from their AI assistant to answer customers faster
  • Let developers check the product map and release timeline from their editor to keep documentation accurate

Can you use it commercially?

Free to use, change and sell, including in paid products. Keep the copyright notice.

Not legal advice. Read the project's licence file before building a product on it.

Add it to Claude Code

claude mcp add --transport http cactus https://mcp.heycactus.ai/mcp

This one runs on the maker's server, not your computer, so what you send it leaves your machine.

From the official MCP Registry (ai.heycactus/cactus). Only connect MCP servers you trust: they can act on your behalf.

Getting it running

Nothing is installed: add the hosted server URL to your AI client (for example with one claude mcp add command) and sign in with a Cactus account via Google or GitHub.

Follow the official instructions in the project README.

Things to check

  • Repository contains no server code, only connection instructions and manifests
  • Requires a paid-service Cactus account and a product built from a GitHub repository
  • Cactus is in closed beta with a waitlist
  • Depends on a closed, hosted third-party service
  • Zero stars and very new
