If you ask an AI to 'clean this HTML before saving it', it will likely fail to catch obfuscated XSS vectors hidden in Base64 or obscure event handlers. LLMs do not have native rendering engines to test payloads. This MCP provides an enterprise-grade security shield for agents that handle public inputs.

The Superpowers

  • Surgical Cleaning: Uses sanitize-html to strip dangerous tags (, ) and malicious onload events.
  • Zero-Trust Input: Enforces a strict whitelist of safe tags, ensuring that what goes into your database cannot execute harmful code in a browser.
