The universal .discovery layer for AI agents.
Publish agents to DNS, discover them like websites, and verify trust with DNSSEC.
DNS-AID lets AI agents discover each other through the internet's existing naming infrastructure — DNS — instead of centralized registries, hardcoded URLs, or new overlay networks.
- Zero new infrastructure — uses the DNS your team already operates.
- DNSSEC trust — agent records are cryptographically verifiable, end-to-end.
- Protocol agnostic — MCP, A2A, HTTPS, anything addressable via SVCB and ALPN.
Agents live under a predictable, federated namespace anchored on a domain you already control:
_{agent-name}._{protocol}._agents.{your-domain}
The _agents label scopes the namespace; _{protocol} carries the transport (_mcp, _a2a, _https); _{agent-name} is the agent's local identifier within your zone.
- Publish — write an SVCB record for your agent into your DNS zone.
- Sign — sign the zone with DNSSEC so consumers can verify provenance.
- Discover — anyone resolves
_{agent-name}._{protocol}._agents.{your-domain}and gets the agent record back. - Validate — verify the DNSSEC chain, optional JWS signatures, and DANE policy before invoking.
| Repository | What it is |
|---|---|
| dns-aid-core | Reference implementation — Python SDK, CLI, and MCP server. The canonical surface for IETF draft-mozleywilliams-dnsop-dnsaid. |
More repositories will land here as the ecosystem develops — integrations, policy compilers, and reference services for the three discovery loci (client, recursive resolver, authoritative).
- Install the SDK:
pip install dns-aid[cli,mcp] - Read the Getting Started Guide: dns-aid-core/docs/getting-started.md
- Try the MCP server: point any MCP-aware client at the reference server and start discovering agents.
- Read the spec: draft-mozleywilliams-dnsop-dnsaid at the IETF.
DNS-AID is a reference implementation of an IETF draft. The specification is developed at the IETF — protocol-level changes belong there. This GitHub organization governs the implementation and ecosystem activities (tooling, examples, integrations, documentation), and is on track for hosting at the Linux Foundation.
