Humanize AI text right where you write
Connect UndetectedGPT to Claude, ChatGPT, Cursor and other AI apps through one MCP server. Your assistant humanizes its own drafts before you ever copy them.
One server, every AI workspace
The Model Context Protocol (MCP) is the open standard for connecting tools to AI assistants. Add UndetectedGPT once and every conversation gets a humanizer it can call on demand.
From signup to humanized output in three steps
No SDK, no webhooks, no code. If you can paste a URL, you can set this up.
- 01
Create an API key
Sign in and generate a key from the developer dashboard. The key carries your word balance, so there is nothing separate to subscribe to.
- 02
Add the connector
Paste your personal MCP URL into your AI app, or run a single command in your terminal. The tools appear in your assistant right away.
- 03
Humanize from chat
Ask your assistant to humanize any draft. It calls UndetectedGPT behind the scenes and replies with text that scores as human on AI detectors.
Set up your app
Get your API key from the dashboard, then follow the steps for your app. In each snippet, replace YOUR_API_KEY with your key.
- 01
In Claude, open Settings, go to Connectors, and click Add custom connector.
- 02
Paste the URL below as the server URL, choose No sign-in, and click Add.
- 03
Start any chat and ask Claude to humanize your text. Custom connectors are available on all plans; free accounts can add one.

Two tools, zero learning curve
Once connected, your assistant sees these tools and knows when to use them. You just write in plain language.
humanize_textHumanize AI text
Rewrites AI-generated text so it reads naturally and passes GPTZero, Originality.ai, Copyleaks and Turnitin. Supports tones, spelling variants, markdown and 100+ languages.
get_account_statusAccount status
Checks the word balance and limits of the connected account, so the assistant knows before a long job whether it will fit.
Questions about the MCP server
The Model Context Protocol is an open standard that lets AI assistants like Claude and ChatGPT call external tools. An MCP server exposes those tools over the internet; this one exposes UndetectedGPT's humanizer, so your assistant can rewrite text without you copying anything between tabs.
Claude on web, desktop and mobile, Claude Code, ChatGPT with developer mode, Cursor, Codex CLI, Windsurf, n8n, Manus, and any other client that supports remote MCP servers over HTTP.
No. It uses the same pay-as-you-go word balance as the API. One input word costs one word, and failed requests are refunded automatically.
The keyed URL exists for apps that cannot send authentication headers. It is only ever served over HTTPS, and you can revoke the key at any time from the dashboard. Clients that support headers should use the Bearer token option instead.
ChatGPT only allows custom MCP connectors through its developer mode toggle, which is available on paid plans. Once enabled, the connector works in regular chats like any built-in app.
The assistant is told the limit and will split long documents into chunks automatically, humanizing them one call at a time and reassembling the result.
