Is the CutGPT MCP server free?

Yes. It is free to use with no sign-up and no API key. Each IP address can make up to 60 requests per minute.

Which AI apps can use it?

Any client that supports remote MCP servers over Streamable HTTP, including Claude (web, desktop, and Claude Code), ChatGPT developer mode, Cursor, VS Code, and Windsurf.

What data does the server keep?

None. It logs only which tool ran, whether it succeeded, and how long it took. It never logs your arguments or results. Queries are sent to the public data source each tool uses.

What is an MCP server?

The Model Context Protocol (MCP) is an open standard that lets AI assistants call outside tools. Adding an MCP server gives your assistant new abilities, in this case looking up fact-checks, papers, and source history.

Can it tell me whether a claim is true?

It finds evidence: published verdicts from fact-checkers, research papers, background, and source history. Your assistant weighs that evidence and should cite it. When no fact-check exists, that is not a verdict either way.
