Draft 2026-W39

Agent Registry Protocol (ARPA) is one author's IETF proposal for how a registry could say who runs an AI agent and what it may do, kept strictly apart from whether the agent exists. It is an individual draft, not a working group document. Useful vocabulary, too early to build on.

C. Drake of 1id.com published revision 04 of an IETF proposal that gives each AI agent a permanent, global identifier, with five trust levels from hardware-backed to software-only. It is an individual Experimental draft. It asks for one central registry and cannot revoke an identity.
