### `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
Audit an email domain in one call: can it receive mail (MX), can it be spoofed (SPF/DMARC/DKIM posture), disposable check. Returns {can_receive, can_be_spoofed, score, reasons, checks}.
```

## Claude Code permissions

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

  "permissions": {
    "allow": [],
    "ask": [
      "mcp__audit__audit_domain"
    ],
    "deny": []
  }
}
