Structural grade · AI Catalog 1.0
Near-Conformant
Correctly shaped — every hard check passes — but optional affordances are missing.
ARD conformance-test v0.9.1 (ards-project/ard-spec)
PASS
Declared identity
resolves
did:web:neuronto.com —
the DID document was fetched, but carries no verification method, so there is nothing to check a signature against.
Discovery path
ard.json
Served at /.well-known/ard.json — the path ARD v0.91 says a consumer MUST fetch.
Declared spec version
1.0
The specVersion in the manifest. 1.0 is current for the AI Catalog data model; anything lower is an earlier draft. ARD reads this field as transport-defined and ignores it.
Neuronto ARD Registry: Agentic Resource Discovery (ARD) registry
urn:air:neuronto.com:registry:neuronto
A federated ARD registry and index. Implements federation: auto with reciprocal rank fusion across every other public ARD registry, normalises the competing MCP media types and URN prefixes so filters do not silently miss, and probes endpoints so dead resources are demoted rather than served.
- “which ARD registries exist”
- “a registry that federates other MCP registries”
- “search every MCP and ARD registry at once”
- “where can I search for MCP servers, skills and agents”
- “how do AI agents discover MCP servers”
ard-publish - build and verify an ARD manifest
urn:air:neuronto.com:tool:ard-publish
Open source tool that builds, validates and verifies an Agentic Resource Discovery manifest, then checks which registries actually return your domain. pip install ard-publish.

- “how do I publish an ARD manifest”
- “make my API discoverable by AI agents”

- “validate my ai-catalog.json”
Neuronto ARD Registry: ARD and MCP discovery (MCP server)
urn:air:neuronto.com:mcp:discovery
The same federated discovery as an MCP server, so an agent can search every ARD registry from the tool interface it already speaks.
- “an MCP server that finds other MCP servers”
- “a tool to search every ARD registry at once”
- “give my agent the ability to discover tools at runtime”
- “search the agent-readable web from one MCP tool”
Evidence. Fetched
https://neuronto.com/.well-known/ard.json on 2026-09-13, HTTP
200. The verbatim body is stored alongside its manifest in the
Neuronto ARD Registry repository
as
ai-catalog/neuronto-ai-catalog.json. Nothing on this page is derived
or generated: an AI Catalog manifest is served from the publisher’s own domain or it does not
exist, which makes it — like an
A2A Agent Card — one of the few agent artifacts that cannot be
produced on a provider’s behalf. Grades are recomputed on every build; the specification is a
v0.9 draft and
these verdicts will move when it does.
Every descriptor here is available over the APIs.io API and to AI agents over MCP. Agent Discovery is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
