Agentic Resource Discovery

Agentic Resource Discovery (ARD) is Google's open specification for publishing, discovering, and verifying agentic resources such as tools, skills, agents, and MCP servers across the web [src-116].

Key points

  • ARD addresses a practical gap in the agentic web: agents need to find where capabilities live, decide which one to use, and verify that connecting to them is safe [src-116].
  • The specification uses catalogs and registries. Catalogs describe capabilities under publisher-controlled domains; registries index them for discovery [src-116].
  • ARD is a discovery and trust layer, not a replacement for every tool protocol. After discovery and verification, the agent can connect through the resource's native protocol [src-116].
  • Google connects ARD to Agent Registry in Gemini Enterprise Agent Platform, with governance primitives such as namespaced URNs, egress policies, pinned tools/specs, Agent Identity, and trust manifests [src-116].

Robin Cartier perspective

This page is part of Robin Cartier's working AI knowledge graph: a practical research layer for production AI, recommendation systems, experimentation, GEO, and agentic web readiness.

The useful next step is to connect this concept back to applied product leadership and operating models.
