WARDEN MCP

A zero-dependency TypeScript library and CLI that acts as an MCP security firewall. It vets MCP server tool definitions against static-scan rules, signed threat feeds, and origin pinning to prevent tool poisoning and data exfiltration before tools reach the model. It supports CLI scanning, stdio wrap proxies, and Claude Code hooks.
