## Findings

- **high** References to secrets on disk in `generate_catalog` ([sensitive-path](https://anlyon.dev/methodology#sensitive-path))

```untrusted-server-text
The description refers to "/.well-known/mcp.json".

description: "...domain. Where the domain already serves /.well-known/mcp.json, the catalog is derived from it, handli..."
```


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `audit_domain`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `generate_catalog`

- The name "generate_catalog" says "generate": a word for a change.
- Findings: high sensitive-path

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `get_capability`

- The name "get_capability" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `search_registry`

- The name "search_registry" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `validate_catalog`

- The name "validate_catalog" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Claude Code permissions
