Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.
Tools: search_registry get_capability audit_domain validate_catalog generate_catalog
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 publisher indexed by Wellknown, plus the caller's own granted tools. Returns ranked results with an identifier you can resolve, the endpoint URL, and provenance s params: query*, limit, published_only |
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 granted identifiers (urn:air:<service>:granted:<you>:<tool>) resolve here too, including the tool's input schema. An entry published with an inline artifact retur params: identifier*, from_query |
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 the official JSON Schema plus additional spec rules, queries live ARD registries to see whether the domain is actually returned, and checks the MCP directories params: domain*, competitors |
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identity, missing representativeQueries (which registries rank on), duplicate identifiers, non-HTTPS artifact URLs, superseded media types, and unsigned trust manifests. Returns a grade and every finding with its JSON path. params: catalog*, domain* |
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 omitted and returned as an explicit to-do list, because a catalog that fabricates capabilities is worse than no catalog. params: domain* |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
