Every one was verified by fetching the manifest, not taken from
another registry's word, out of 376,142 domains checked. The
440 listed below are those whose declared resources we also index, together
declaring 13,601 of them. The remaining 96 serve a manifest on one
host while the resources it declares belong to another, the way
connectors-skills.zapier.com publishes for zapier.com, so they
appear here under the domain that owns the resources.
The Agentic Resource Discovery specification defines a publisher as whoever hosts a manifest describing one or more agentic resources, at a well-known path on their own domain. It is how a website tells an AI agent what it can call: which MCP servers, skills, agents and APIs exist here, and what each is for.
This list is manifest publishers only, because that is what the specification
defines and what the title claims. Plenty of domains run an MCP server without ever
publishing a manifest, and those are indexed too and have their own page at
/ard-publishers/<domain>, describing what we observed rather than what
they declared. They are not counted here because they have not published anything to count.
If that is your domain, publishing a manifest takes about ten minutes
and lists everything you offer, not only what MCP happens to expose.
Version 0.91 renamed the manifest to /.well-known/ard.json, and
the deployed base has not followed: 234 of these publishers still serve the
older /.well-known/ai-catalog.json and only 206 serve the new
name. Anything reading the ecosystem has to request both, and a tool that checks only
ard.json will conclude, wrongly, that almost nobody has adopted the spec.

Serve one JSON file describing what you offer, at both well-known paths while the rename settles. The publishing guide is the ten-minute version, and the free console shows exactly what a registry sees when it reads your domain. There is no application and no allowlist: publish the file and crawlers find it.
