PII Redactor MCP Server

An MCP (Model Context Protocol) server that provides PII (Personally Identifiable Information) redaction capabilities to AI assistants like Claude Desktop, Cursor, and Windsurf.

Features

sanitize_text — Detect and redact PII from any text (emails, phone numbers, credit cards, SSNs, IBANs, IP addresses, crypto wallets)
health_check — Verify the API is available

Quick Start

1. Get an API Key

2. Configure Your AI Assistant

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %AppData%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "pii-redactor": {
      "command": "npx",
      "args": ["-y", "pii-redactor-mcp"],
      "env": {
        "PII_REDACTOR_API_KEY": "your-rapidapi-key-here"
      }
    }
  }
}

Cursor

Add to your Cursor MCP settings:

{
  "mcpServers": {
    "pii-redactor": {
      "command": "npx",
      "args": ["-y", "pii-redactor-mcp"],
      "env": {
        "PII_REDACTOR_API_KEY": "your-rapidapi-key-here"
      }
    }
  }
}

Windsurf

Add to your Windsurf MCP configuration:

{
  "mcpServers": {
    "pii-redactor": {
      "command": "npx",
      "args": ["-y", "pii-redactor-mcp"],
      "env": {
        "PII_REDACTOR_API_KEY": "your-rapidapi-key-here"
      }
    }
  }
}

3. Use It

Ask your AI assistant:

"Redact PII from: My name is John, email john@acme.com, SSN 123-45-6789"

The assistant will call the sanitize_text tool and return the redacted text.
