How to Humanize AI Text in Claude & Cursor via MCP

Tired of copying AI drafts into a browser tab to humanize them? With the GPT Scrambler MCP server, Claude Desktop, Cursor, and Claude Code can rewrite AI-generated text inline — using the same engine as GPT Scrambler and passing detectors like GPTZero and Turnitin.

This guide walks you through setup in under five minutes.

What you get

humanize_text — send AI copy, get human-sounding output back
get_balance — check remaining API/MCP words before a big job
200-word free trial — separate from your web balance, no credit card
Same quality as the website — identical prompts and modes (standard / aggressive)

Package: @gptscrambler/mcp-server on npm · GitHub source

Step 1: Get your API key

Sign up free if you do not have an account.
Open Settings → API Access.
Click Generate API key. Copy the sk_live_... value — it is shown once.
You start with 200 free API/MCP words for testing.

Need more volume? The API Plan ($49.99/mo) includes 100,000 words and MCP access.

Step 2: Add MCP config

Use the same JSON block everywhere — only the file path changes:

{
  "mcpServers": {
    "gpt-scrambler": {
      "command": "npx",
      "args": ["-y", "@gptscrambler/mcp-server"],
      "env": {
        "GPTSCRAMBLER_API_KEY": "sk_live_your_key_here"
      }
    }
  }
}

Claude Desktop

| Platform | Config file | |---|---| | macOS | ~/Library/Application Support/Claude/claude_desktop_config.json | | Windows | %APPDATA%\Claude\claude_desktop_config.json |

Merge the block above under mcpServers, save, and restart Claude Desktop.

Cursor

Add to Cursor Settings → MCP, or create:

Project: .cursor/mcp.json in your repo root
Global: ~/.cursor/mcp.json

Cursor reloads MCP config automatically.

Claude Code

Add the same JSON to ~/.claude.json or a project .mcp.json. Your terminal agent can then call humanize_text while you code or write docs.

Step 3: Humanize text in conversation

Try prompts like:

"Humanize this paragraph using GPT Scrambler: [paste text]"
"Check my GPT Scrambler balance, then rewrite this email in aggressive mode"
"Make this ChatGPT draft sound natural — use humanize_text"

The agent invokes the MCP tool and returns the result in the same thread. No browser, no manual paste.

REST API alternative

Prefer code over MCP? Use the same API key:

curl -X POST https://gptscrambler.com/api/v1/humanize \
  -H "Authorization: Bearer sk_live_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{"text": "Your AI-generated text...", "mode": "standard"}'

See the REST API reference for error codes and limits (10–3,000 words per request).

Troubleshooting

| Issue | Fix | |---|---| | Tool not visible | Restart Claude Desktop; verify JSON syntax | | 401 invalid_api_key | Regenerate key in API Access settings | | 402 insufficient_balance | Upgrade or wait for monthly reset | | Wrong npm package | Use @gptscrambler/mcp-server, not deprecated gptscrambler-mcp-server |
