Legant is an open-source delegated authorization server for AI agents, written in Go, that provides scoped, time-boxed, revocable, and auditable authority. It uniquely combines RFC 8693 token exchange with monotonic attenuation and offline constraint enforcement, making it a novel infrastructure component for safe AI agent delegation.

Target audience: backend devs, devops, security engineers
