## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `internet_tape`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
The rolling 24-hour aggregate rollup: how many domains changed DNS provider, switched certificate authority, moved mail, went unreachable, and the other tape legs, each with a live count. Public and keyless.
```

### `signing_keys`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
The Ed25519 public keys that sign every DomainDrift observation, with derivation paths and validity windows. Public and keyless. Use these to verify receipts and signed records offline.
```

### `whats_changed_today`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
The daily "what changed on the internet" digest: a ranked top-20 of the most significant DNS, TLS, WHOIS, and infrastructure changes observed across the tracked catalog in the last 24 hours. Public and keyless. The complete change wire with sync cursors is the keyed /v1/changes endpoint.
```

## Only reads (2)

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

### `lookup_domain`

- The name "lookup_domain" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The latest signed observation of one domain: who runs its nameservers, mail, and CDN; certificate issuer and expiry; HTTPS reachability; per-record-type counts; and the Ed25519 receipt pointer. Keyless calls get this reduced preview, throttled to 1 request per 15 seconds per IP under a shared daily ceiling. Connect with a DomainDrift API key in an Authorization: Bearer header to get the complete signed record instead, metered against your account like any API request.
```

### `resolve_receipt`

- The name "resolve_receipt" says "resolve": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Resolve any DomainDrift provenance receipt by id: the public Ed25519 commitment (output hash, signing key, timestamp, chain link) for one observation. Public and keyless. Verify the signing key against /.well-known/domaindrift-keys.json.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `domaindrift`:

```json
{
  "permissions": {
    "allow": [
      "mcp__domaindrift__lookup_domain",
      "mcp__domaindrift__resolve_receipt"
    ],
    "ask": [
      "mcp__domaindrift__whats_changed_today",
      "mcp__domaindrift__internet_tape",
      "mcp__domaindrift__signing_keys"
    ],
    "deny": []
  }
}
```
