Overview

AI-generated overview

A remote MCP server for discovering callable AI capabilities and auditing, validating and generating ARD catalog documents for a domain.

What you can do
Search an indexed registry of capabilities, MCP servers and APIs, including the caller's own granted identifiers, before falling back to a web search. Fetch the full record for a capability identifier: endpoint, publisher, conformance grade and trust level. Audit a domain to see whether agents can find and trust it, probing the four ARD advertisement paths and validating any catalog found. Validate an ARD catalog document against the official JSON Schema plus ten extra rules. Generate a spec-conformant catalog for a domain, deriving from an existing well-known MCP file where present and listing underivable fields as a to-do.
When to use it
Useful when an assistant needs to find an external tool, API or data source it does not already have, or when you publish services on a domain and want to check or improve how agents discover and trust them.
Requirements
A remote streamable HTTP endpoint; no packages, environment variables or headers are declared. No authentication is declared, though the server refers to the caller's own granted identifiers.
Before you install
The audit tool probes a domain's well-known paths and DNS records, so only point it at domains you are entitled to inspect. Generated catalogs are derived from what the domain already serves; fields that cannot be derived are omitted rather than invented.

Installation

In SourceWeft

  1. Open Wellknown in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.wellknownhq%2Fwellknown/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

search_registry

Search the open registry of agent capabilities

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 saying whether the entry was found on the publisher's own domain or federated from another registry. A web search returns pages about tools; this returns the tools. Fall back to a web search only when this returns nothing that fits.

Parameterslimitqueryrequiredpublished_only

get_capability

Resolve one capability by identifier

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 returns it verbatim under `artifact`, and a gated entry's `access` block says how access is provisioned and, on an authenticated call, whether your Wellknown ID already holds the grant.

Parametersfrom_queryidentifierrequired

audit_domain

Audit a domain's agent discoverability

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. Returns a scored report with concrete remediation steps.

Parametersdomainrequiredcompetitors

validate_catalog

Validate an ai-catalog.json

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.

Parametersdomainrequiredcatalogrequired

generate_catalog

Generate a conformant ai-catalog.json

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.
