Abstract

The proliferation of AI agents requires robust mechanisms for secure discovery. This document introduces the Agent Name Service (ANS), a novel architecture based on DNS addressing the lack of a public agent discovery framework. ANS provides a protocol-agnostic registry mechanism that leverages Public Key Infrastructure (PKI) certificates for verifiable agent identity and trust. The architecture features several key innovations: a formalized agent registration and renewal mechanism for lifecycle management; DNS-inspired naming conventions with capability-aware resolution; a modular Protocol Adapter Layer supporting diverse communication standards (A2A, MCP, ACP, etc.); and precisely defined algorithms for secure resolution. This specification describes structured communication using JSON Schema and includes a comprehensive threat analysis. The result is a foundational agent directory service protocol addressing the core challenges of secure discovery and interaction in multi-agent systems, paving the way for future interoperable, trustworthy, and scalable agent ecosystems.
