Agent Identity Registry Protocol Community Group
W3C Community Group (launched 2026)
Agent Identity Registry Protocol Community Group (W3C Community Group (launched 2026)) is W3C, Proposed 22 April 2026. Shows that 'agent identity' is being pursued in W3C as well as IETF. Overlaps AAuth/WIMSE problem space from a VC angle.
At a glance
- Problem
- AI agents need cryptographically verifiable credentials binding them to controlling organizations so they can negotiate trust across orgs without bilateral contracts in advance.
- Identity / authn / authz
- Identity infrastructure (DID method, VC format, trust levels, revocation). Integration profiles planned with MCP, A2A, OAuth/OIDC, SPIFFE.
Actors
- Controlling organization
- Agent
- Relying organization
When this matters for agents
When this matters for agents: shows that 'agent identity' is being pursued in W3C as well as IETF, from a DID/VC angle, with planned MCP/A2A/OAuth/SPIFFE profiles. Community Group ≠ Recommendation. Watch for drafts before implementing. Overlaps AAuth/WIMSE problem space.
Flow in plain language
Not a finished protocol at research time. Charter lists DID method, agent credential format, trust negotiation, lifecycle, post-quantum requirements.
Implementer notes
Community Group ≠ W3C Recommendation. W3C hosting is not endorsement. Watch for drafts before implementing.
