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.

Powered by the PII Redactor API on RapidAPI.

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

Sign up at RapidAPI and subscribe to the PII Redactor API.

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 [email protected], SSN 123-45-6789"

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