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)
FAIL
Run against this exact body with the project’s own
conformance CLI — 3 critical errors.
Discovery path
predecessor
Answered only at /.well-known/ai-catalog.json. ARD v0.91 renamed the path to /.well-known/ard.json and made the old one an optional courtesy, so a consumer implementing only the current spec will not find this manifest.
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.
Listen Labs MCP Server
urn:air:listenlabs.com:server:mcp
Remote MCP server for Listen Labs. Lets AI assistants create and edit studies, launch participant recruitment, browse and organize studies, search across research, and read transcripts and analysis reports. Stateless streamable HTTP transport with OAuth 2.0 automatic discovery.
- “create a user interview study about onboarding friction”
- “launch recruitment for my pricing study”
- “what did participants say about checkout in my latest study”
- “summarize the analysis report for my concept test”
Listen Labs API
urn:air:listenlabs.com:api:v2
REST API to create, launch, and retrieve data from Listen Labs studies programmatically: create and launch studies, list studies and wallets, fetch study questions, and retrieve participant responses.
- “programmatically create and launch a study”
- “retrieve all responses for a completed study”

urn:air:listenlabs.com:docs:llms-txt
Agent-readable llms.txt index of the Listen Labs product documentation, including the API reference and MCP connection guides.
Evidence. Fetched
https://listenlabs.ai/.well-known/ai-catalog.json on 2026-09-13, HTTP
200. The verbatim body is stored alongside its manifest in the
Listen Labs repository
as
ai-catalog/listen-labs-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.
