- The Agent Auth Protocol is an open-source standard designed for AI agent authentication, authorization, and service discovery.
- It addresses key challenges for long-lived AI agents, including delegated access, autonomous operation without human oversight, and standardized service discovery.
- The protocol enables cryptographically verifiable identity and capability-based authorization, aiming to replace insecure bearer tokens with secure, signed HTTP messages.
- Official implementations and SDKs are provided to support developers in building secure agentic systems.
