brehon-mcp-server

Privacy and AI regulation data for your AI assistant.

Stop your AI from hallucinating privacy law requirements. Brehon gives Claude, Codex, Cursor, VS Code, and Open Code structured access to 32 privacy and AI governance laws across 28 jurisdictions — grounded in real regulatory data, not training data.

Why?

When you ask an AI assistant "what privacy laws apply to my app in Brazil?", it answers from training data that might be outdated, incomplete, or wrong. Getting privacy compliance wrong means fines — GDPR alone goes up to 4% of global revenue.

Brehon fixes this. Your AI calls the Brehon API in real time and gets structured, current regulatory data.
