概要

What is Policylayer MCP Registry?

Policylayer MCP Registry is a hosted MCP server that vets any MCP server by returning its published safety record: verified identity, A–F risk grade, auth posture, and a risk classification for every tool. It covers 32,500+ published servers and 515,000+ classified tools via continuous scanning.

How to use Policylayer MCP Registry?

Connect your agent to the streamable HTTP endpoint (https://api.policylayer.com/mcp) using Claude Code (claude mcp add --transport http policylayer https://api.policylayer.com/mcp) or configure it in Claude Desktop, Cursor, Windsurf, or VS Code as a custom MCP connector. Then instruct your agent to check any server against PolicyLayer before installing. Free single-server lookups require no key.
