## When to use which

- Choose Identity Assertion JWT Authorization Grant when your question is “How can an app or AI agent, already SSO-federated to a user's enterprise identity provider, obtain scoped access to a third-party API or MCP server without a fresh consent screen at that third party?” and you accept its maturity: status "Active Internet-Draft, WG Document (oauth WG); Intended status: Standards Track (per document front matter); IESG state: I-D Exists", implementation multi-implementation.
- Choose OAuth Profile for Delegated AI Agent Authorization when your question is “How can a human user delegate constrained, attenuable, revocable authority to an AI agent using standard OAuth mechanisms, with no new endpoints or claims required?” and you accept its maturity: status "Internet-Draft, individual submission, Active", implementation prototype.

Guidance is derived from the two records (question, status, implementation, prerequisites, pairings), not from opinion. Each record's page carries its numbered references.
