Agent Identity URI Scheme Enables Decentralized, Topology-Independent Naming and Discovery for Multi-Agent Systems

Jul 15, 2026

A new preprint introduces the agent:// URI scheme, designed to decouple agent identity from network location in multi-agent systems. The scheme incorporates trust roots, hierarchical capability paths, and sortable unique identifiers, with cryptographic attestation using PASETO tokens. Evaluation demonstrates full capability expressiveness on 369 tools, perfect discovery precision across 10,000 agents, and sub-5-microsecond performance, suggesting a robust and scalable approach to agent identity and discovery.

Why it matters: This work proposes a novel, decentralized solution to agent identity and discovery, potentially enabling more robust and scalable multi-agent ecosystems.
