Documentation Overview

StyleMCP

Executable brand rules for AI models and agents. Keep every AI-generated message on-brand.

What is StyleMCP?

StyleMCP validates and rewrites AI-generated text to match your brand voice. Use it as:

REST API - Validate text from any application
MCP Server - Direct integration with Claude and other AI agents
CLI - Check copy in your terminal or CI/CD
GitHub Action - Catch off-brand copy in pull requests

Quick Start

API

Terminal

curl -X POST https://stylemcp.com/api/validate \
  -H "Content-Type: application/json" \
  -d '{"text": "Click here to learn more!"}'

Response:

config.json

{
  "valid": false,
  "score": 65,
  "violations": [
    {
      "rule": "no-click-here",
      "severity": "error",
      "message": "Avoid 'click here' - describe the destination instead",
      "suggestion": "Learn more about our features"
    }
  ]
}

CLI

bash

# Install
npm install -g stylemcp

# Validate text
stylemcp validate "Click here to learn more"

# Validate file
stylemcp validate src/copy/homepage.json --pack saas

# Rewrite text
stylemcp rewrite "Please utilize our product" --mode aggressive

MCP (Claude Desktop)

Add to your claude_desktop_config.json:

config.json

{
  "mcpServers": {
    "stylemcp": {
      "command": "npx",
      "args": ["stylemcp"]
    }
  }
}

Now Claude can validate and rewrite text using your brand rules.
