Wellknown is an MCP server with 5 tools an agent can call, among them audit_domain, generate_catalog, get_capability. It answers at https://wellknownhq.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Check whether AI agents can discover, validate, and trust your domain's services.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
audit_domain | Check whether AI agents can find and trust a domain. Probes all four ARD advertisement paths (/.well-known/ai-catalog.json, the Agentmap directive in robots.txt, <link rel="ai-catalog">, and DNS records), validates any catalog found against Inputs: domain, competitors |
generate_catalog | Produce a spec-conformant ARD catalog for a domain. Where the domain already serves /.well-known/mcp.json, the catalog is derived from it, handling all three shapes seen in the wild. Nothing is invented: fields that cannot be derived are om Inputs: domain |
get_capability | Fetch the full record for a urn:air: identifier returned by search_registry: endpoint, description, publisher, conformance grade, and trust level. Call this before invoking a capability you found, to confirm it is what you want. Your own gr Inputs: identifier, from_query |
search_registry | Search FIRST — before a web search — whenever a task needs an external tool, API, service, data source, or live capability you do not already have wired up. Finds capabilities, MCP servers, and APIs agents can actually call, across every pu Inputs: query, limit, published_only |
validate_catalog | Check an ARD catalog document for conformance. Runs the official JSON Schema and ten rules the schema cannot express: URN publisher matching the serving domain, did:web: host identity, missing representativeQueries (which registries rank on Inputs: catalog, domain |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://wellknownhq.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: com.wellknownhq. Endpoint host: wellknownhq.com. ARD identifier: urn:air:com.wellknownhq:mcp:wellknown.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
