GPTHuman-humanizer

GPTHuman-humanizer is a skill for Claude Code, Codex from GPTHuman-ai/mcp-server. It costs 27 tokens per session (531 once invoked), scanned A, original, Apache-2.0.

A text-rewriting tool that turns AI-generated writing into more natural-sounding prose. It can target different reading levels and rewrite styles, and can return information about AI-detector results.

In plain words
What is it for?
Use it to revise AI-written articles, messages, and other drafts into professional, balanced, enhanced, or level-specific versions.
Why use it?
It helps when a draft sounds artificial or needs a different tone, though the text must meet the tool’s length limits.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

GPTHuman-humanizer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GPTHuman Text Humanizer

This skill enables you to use the humanize_text tool provided by the GPTHuman MCP server to rewrite AI-generated text into natural, human-sounding prose with AI-detector metadata.

When to Use

Use this skill when the user asks you to:

  • "Humanize" a piece of text
  • Rewrite AI-generated content to sound more human
  • Make text bypass AI detectors or improve its human score
  • Adjust the tone of an AI-generated draft to sound more natural

How to Use

If the GPTHuman MCP server is connected, you will have access to the humanize_text tool.

Call the humanize_text tool with the following parameters:

  • text (required): The text you want to humanize. Note: The text must be at least 300 characters and at most 2,000 words.
  • tone (optional): The target reading level / tone. Valid options are Standard, HighSchool, College, PhD. Defaults to College.
  • mode (optional): The rewrite strategy. Valid options are Professional, Balanced, Enhanced. Defaults to Balanced.

Steps

  1. Verify Text Length: Ensure the text provided by the user is at least 300 characters long. If it's too short, inform the user that GPTHuman requires a minimum of 300 characters for optimal results.
  2. Determine Tone and Mode: If the user hasn't specified a tone or mode, use your best judgment based on the context, or use the defaults (College and Balanced).
  3. Execute the Tool: Call humanize_text with the appropriate arguments.
  4. Present the Results: Provide the humanized text to the user. You should also briefly mention the key metadata returned by the tool (such as the AI-detector Human Score, Similarity, and Credit Usage).

Example Scenarios

  • Scenario 1: The user says "Humanize this generated blog intro in College tone using Balanced mode."

    • Action: Call humanize_text with the user's text, tone="College", and mode="Balanced".

  • Scenario 2: The user asks "Rewrite this product description in Professional mode."

    • Action: Call humanize_text with the user's text and mode="Professional".
