Asking the model that wrote a passage to make it sound less like itself rarely helps; routing it through a different service is the point. Because a model may quietly rewrite the text itself instead of calling the tool, naming humantone in the request is what reliably routes it. The detector is free of credits, so scoring a draft costs nothing.
HumanTone's official MCP server. It brings the humanizer and the AI-likelihood detector from the HumanTone web app into your assistant, drawing on the same account and the same credits.
- humanize — rewrite text to read as human-written, taking custom instructions for tone, audience and terminology to preserve
- detect_ai — an AI-likelihood score from 0 to 100; it consumes no credits and allows 30 checks a day, shared with the web app
- get_account — the current plan, remaining credits and subscription status
A paid HumanTone plan with API access — free trial accounts cannot use the API — and a key from the account settings page in HUMANTONE_API_KEY. Nothing to install: the client downloads and runs npx -y humantone-mcp on first launch. Node.js 18 or newer.
One command plus a key — npx humantone-mcp, then supply credentials
