Overview

What is HumanTone?

HumanTone is the official Model Context Protocol server for HumanTone, an AI text humanizer that rewrites AI-generated content to sound more natural. It brings HumanTone’s humanize and AI likelihood tools directly into Claude Desktop, Cursor, Cline, and other MCP clients using a single API key and the same credits as the web app.

How to use HumanTone?

No installation is needed – the client downloads the package on first launch via npx humantone-mcp. Configure the MCP client with a JSON snippet that sets command to npx, args to ["-y", "humantone-mcp"], and env with your HUMANTONE_API_KEY. Then restart the client and prompt the assistant naturally to use the tools.

Frequently asked questions

1

Why don’t the tools appear in my assistant?

Confirm the JSON configuration has no syntax errors, then fully quit and reopen the MCP client – a window refresh is not enough.

2

What does “Invalid API key format” mean?

HumanTone API keys are 67 characters: `ht_` followed by 64 hex characters. Generate a new one at app.humantone.io/settings/api if unsure.

3

Why do I get “Plan does not include API access”?

Free trial accounts cannot use the API. You need a paid HumanTone plan; view options at humantone.io/pricing.

4

I get “npx: command not found”. What do I do?

Install Node.js version 18 or later from nodejs.org.

5

How many AI detection checks can I do per day?

30 checks per day, shared with the HumanTone web app. Detection does not consume credits.
