What the publisher says

From the DNS Aid repository's README, as published. We do not edit it. Read it on GitHub

DNS-AID

<!-- mcp-name: io.github.dns-aid/dns-aid -->

DNS-based Agent Identification and Discovery

Reference implementation for IETF draft-mozleywilliams-dnsop-dnsaid-02.

DNS-AID enables AI agents to discover each other via DNS, using the internet's existing naming infrastructure instead of centralized registries or hardcoded URLs.

Relationship to IETF

The DNS-AID specification is being developed within the IETF: https://datatracker.ietf.org/doc/draft-mozleywilliams-dnsop-dnsaid/.

This repository provides a reference implementation.

This project does not define the specification. The IETF draft is authoritative.

Scope of this Repository

This project focuses on implementation, tooling, and ecosystem activities.

Changes to protocol behavior should be discussed within the IETF.

Ecosystem and Integrations

DNS-AID is a substrate. The library in this repository is sufficient on its own — it publishes and resolves agent records against any DNS provider, with no dependency on a particular directory, indexer, or telemetry backend.

When a search, indexing, or telemetry layer is useful, the SDK can point at any HTTP endpoint that implements the documented interfaces. Operators are encouraged to run their own — the indexer is a thin layer over the same DNS records this library publishes and discovers, and the SDK telemetry sink is configurable via DNSAIDSDKHTTPPUSH_URL (off by default). Independent directory implementations exist across the ecosystem; DNS-AID is designed to remain interoperable with any of them rather than canonicalize a single one.

Quick Start

Install

# Install from PyPI
pip install "dns-aid[cli,mcp]"

# Or install the latest unreleased main from GitHub
pip install "dns-aid[cli,mcp] @ git+https://github.com/dns-aid/dns-aid-core.git"
