Zyrax Guard MCP Server

Audit your AI agent configs before you run them. Catch the prompt injection, malicious MCP servers, and credential-exfil hiding in the files that steer your AI - CLAUDE.md, .mcp.json, agent settings, skills - and vet the packages they pull in. In milliseconds. Nothing leaves your machine. It runs locally over stdio via the published package.

People connecting security tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Go.
