Google’s open standard for AI agents to discover and verify tools

The document describes Agentic Resource Discovery (ARD), an open specification for publishing and discovering AI agent capabilities across domains using catalogs (ai-catalog.json) and searchable registries; it outlines the ARD workflow (publish, discover, verify, connect), trust and identity mechanisms, and Google Cloud’s Agent Registry support in the Gemini Enterprise Agent Platform. It notes enterprise governance features, planned onboarding and identity verification, and that the specification is available now under the Apache 2.0 license with implementation guidance on GitHub.
