Introducing Iya-STS v1.0.0: Identity Integration for the AI Era
Iya-STS is an identity provider and integration platform. It started as a mock Security Token Service inside the Identity Protocol Debugger, built to test identity integrations, and grew into directory services, PKI, authorization engines, and federation until it had a purpose of its own.
Most organizations already run several identity products across different protocols and trust relationships. Iya-STS brings twelve areas of identity standards together, so applications don’t have to deal with each provider and token format separately.
As AI agents, MCP-based systems, and workload identities join human users, token exchange (RFC 8693) and delegation matter more, because systems need to know who is acting and on whose authority.
Version 1.0.0 also coincides with the OpenID Foundation publishing our OpenID Connect certifications: eleven conformance profiles across OpenID Provider and Logout. That program is self-certification, and the test data is public.
The full protocol list is in the graphic. More is planned.
