Agentic Resource Discovery (ARD): open standard for runtime agent capability search
Hugging Face launched its reference implementation of the Agentic Resource Discovery (ARD) spec — a draft open standard developed with contributors from Microsoft, Google, GoDaddy, and others — which defines how agents find MCP tools, skills, and other agents across federated registries at runtime instead of requiring pre-installation. The HF Discover Tool exposes thousands of Hub Spaces, MCP servers, and Agent Skills through a REST API (`POST /search`) and MCP endpoint, serving results as typed catalog entries (`application/ai-skill`, `application/mcp-server+json`). The spec uses a static `ai-catalog.json` manifest at a well-known URL plus a dynamic search API, and HF CLI ships a `hf discover search` command out-of-the-box.
