Transform AI-generated text into natural, human-sounding content that bypasses AI detectors.
Transform AI-generated text into natural, human-sounding content that bypasses AI detectors. The humanizer mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 6 defined tools rather than through you.
A Model Context Protocol (MCP) server providing access to GPTHuman's API, the leading platform for rewriting AI-generated text into more natural, human-sounding prose, with AI-detector metadata returned when available. This allows any MCP-compatible client (Cursor, Claude Desktop, etc.) to call the humanizer tool natively.
Everything the assistant can do here goes through one of these:
Privacy — ** Submitted content is private and is not used for retraining AI modelsScript — DescriptionCursor — Add the server to ~/.cursor/mcp.json (or your workspace .cursor/mcp.json):humanize_text — Transforms AI-generated text into a more natural, human-sounding variant designed to bypass AI detectors, while preserving the requested tone andEndpoint — The Endpoint tool exposed by this serverParameters — The Parameters tool exposed by this serverBeing a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
You will need 2 environment variables: GPTHUMAN_API_KEY, YOUR_GPTHUMAN_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Humanizer's toolset — Privacy, Script, Cursor and 3 more — is a fair guide to whether it matches your workflow. It is maintained by GPTHuman-ai; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Humanizer's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
