Neuronto ARD Registry
Agentic Resource Discovery (ARD) registry and MCP index. Ask once and get ranked, verified answers from this index and every other public ARD registry at the same time, plus a tool index read from each MCP server's own tools/list. Also publishes: it can build and verify an ARD manifest for a domain and get that domain listed.
AgentCard object — a capabilities object, a declared protocolVersion, and a well-formed skills array.
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

Find an agentic resource find_resource
Search for an MCP server, skill, agent, API or other callable capability for a task, across this index and every other public ARD registry at once. Returns ranked matches with the endpoint to connect to and which registries carry each result. The score is relevance only, never a trust or safety rating.
discoverysearchmcpardagentstoolsFind a specific tool find_tool
Search individual tools rather than whole servers. Every tool was read from the server's own tools/list or its published OpenAPI document, so the name and description are the publisher's, not a directory's summary of it.
toolssearchmcpverifiedRegistry statistics registry_stats
How many entries, publishers and verified tools this index holds, how many endpoints answer, and which registries it federates.

Work with this as data
Every agent card here is available over the APIs.io API and to AI agents over MCP. A2A Agent Cards is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
