Hugging Face launches ARD discovery tool so agents can search for tools, skills, and other agents

Agentic Resource Discovery: Let agents search

Hugging Face released Discover Tool, a reference implementation of the Agentic Resource Discovery (ARD) spec. ARD is an open draft co-developed by Microsoft, Google, GoDaddy, Hugging Face, and others. It lets agents find MCP tools, A2A agents, or skills at runtime via natural-language search instead of hardcoding each one. Hugging Face's implementation wraps the Hub's existing semantic search and Agent Skills into an ARD catalog, exposed as a REST API and an MCP Tool. The post does not disclose pricing, search latency, or accuracy figures.

Why it matters: ARD tackles a real pain point—agent tool discovery—with cross-vendor backing from Microsoft, Google, and Hugging Face, plus a working reference implementation. Not scoring higher because it's still an open draft, not a ratified standard, and the post doesn't spell out adoption...
