Agent Master Key is a macOS app (macOS 14+, Apple Silicon) that keeps your provider API keys in an AES-256-GCM encrypted vault on your own Mac and brokers AI agents' access. Each agent gets one scoped, revocable amk_live_ key instead of your real credentials — with local approval prompts for risky actions, a kill switch that pauses every agent at once, and a tamper-evident audit trail.
