A new approach called UCAN delegation is proposed to enhance the security of AI agents by providing them with limited, time-bound permissions rather than permanent API keys. This method, inspired by the analogy of a passport and visa for international travel, allows users to grant specific capabilities to agents for a defined duration. The UCAN system uses cryptographically signed JSON objects to define issuer, audience, allowed actions, and expiration, ensuring that agents can only perform actions explicitly authorized and for a limited time, thereby mitigating risks associated with agent misbehavior or security breaches.
