Anthropic This document profiles the Agent Identity Management System (AIMS) framework for agent platforms that host many agent instances per customer. Each agent is identified by an opaque, non-reassignable agent identifier; the agent obtains access tokens by presenting a JWT authorization grant (RFC 7523), signed by the platform's per-tenancy issuer, in the assertion parameter at the authorization server protecting the resource server. Trust is established once, by reference to the issuer's published metadata and keys; agent creation requires no per-agent step at the authorization server or resource server; and authorization is expressed over platform-asserted agent properties that resource servers map locally to permissions. This profile addresses agents acting on their own behalf; access on behalf of a user or other principal is out of scope, though the design is intended to compose with existing delegation mechanisms in which the agent appears as the actor.
