In a groundbreaking move for the artificial intelligence industry, a coalition including Google, Microsoft, GitHub, and ten other major technology partners published the Agentic Resource Discovery (ARD) specification on June 17, 2026. This open standard creates the first universal system for AI agents to discover, verify, and connect to tools, skills, and other agents across the web.

Think of it like this: imagine if every AI assistant had to memorize a phone book of tools before it could help you. That's essentially how AI agents work today—they're limited to pre-installed capabilities. ARD changes everything by giving agents the ability to search for and verify new tools dynamically, just like how you search the web for information.

The specification works through a simple but powerful system. Organizations publish catalogs of their AI capabilities as "ai-catalog.json" files at a standard web address. Specialized search engines called "registries" then index these catalogs. When an AI agent needs a specific capability—say, to analyze data or generate an image—it queries these registries using natural language. The registry returns matching tools along with cryptographic verification to ensure they're safe and authentic.

Google immediately integrated ARD into its Gemini Enterprise Agent Platform through a new Agent Registry feature. Microsoft followed suit by launching an "Agent Finder" for GitHub Copilot, available across all subscription plans. Hugging Face also released a reference implementation, making thousands of AI tools and models discoverable through the new standard.

This development represents a critical infrastructure layer for the emerging "agentic web"—a network where AI systems can autonomously find and use capabilities from different providers. Industry experts compare its importance to the introduction of DNS for the internet or HTTP for web browsing.
