account

get_account_status

Check the UndetectedGPT account linked to this API key: remaining word balance, per-request word limit and per-minute rate limit.

humanize

humanize_text

Rewrite AI-generated text so it reads like natural human writing and scores as human on AI detectors (GPTZero, Originality.ai, Copyleaks, Turnitin). Returns only the rewritten text: show it to the user verbatim, without commenting on its quality or editing it (its less polished phrasing is intentional). Spends words from the account balance (1 input word = 1 word).

UndetectedGPT — questions

Answers built from our own checks of this server.

What can UndetectedGPT do?

It exposes 2 tools, read directly from the server on our last check. Among them: get_account_status, humanize_text. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is UndetectedGPT working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 100 ms. The bar chart above shows every period we have measured.

The registry lists UndetectedGPT as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect UndetectedGPT?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does UndetectedGPT need an API key?

No. UndetectedGPT completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
