AID is a minimal, open standard that answers one question: \"Given a domain name, where does its agent interaction begin?\" It uses a single DNS TXT record to make any agent service—whether it speaks MCP, A2A, or another protocol—instantly discoverable. No more digging through API docs, no more manual configuration. Built by the team at agentcommunity.org v2.1 Release Status AID v2 is the current normative protocol surface in packages/docs/specification.md . packages/docs/specification v2 explained.md remains as non-normative design history. - Record version: new generated records default to v=aid2 . - PKA key: k / pka is the unpadded base64url Ed25519 JWK x value. - Key identity: HTTP Message Signature keyid is the RFC 7638 JWK thumbprint derived from k ; v2 records do not publish DNS kid / i . - PKA challenge: clients request an RFC 9421 response signature with Accept-Signature and a nonce. - Freshness: v2 PKA requires created , expires , exact nonce echo, and response Cache-Control: no-store . - Domain binding: for aid2 PKA, clients send the queried host in the AID-Domain header by default and report a domainBound indicator ( true only for a verified domain-bound proof — one whose aid-pka-v2 covered set includes \"aid-domain\";req ). Requesting binding does not by itself mitigate unauthorized association — only domain-binding=require enforces it.
