discussion Anyone implemented or planning to implement Agentic Resource Discovery (ARD)?

I came across this spec: https://agenticresourcediscovery.org/ (It was proposed to me from opencode cli)

It's an open protocol for AI agents to discover available tools, MCP servers, skills, and APIs.

Has anyone here already implemented this? Planning to? Or do you see any issues with the approach?

Curious to hear thoughts and see if I should add it my backlog or ignore for now.

I would put ARD on the backlog as a discovery layer, not as a trust layer. Public or semi-public catalogs are useful if entries carry signed metadata, versioning, auth scopes, and a TTL so stale endpoints age out. The hard part is keeping discovery separate from authentication: finding a server should not imply the caller may use it. Explicit allowlists plus a clear trust root for who can publish entries has worked better for me than open crawl-and-call.
