## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `dns_records`

- 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
DNS records for a domain: A, AAAA, MX, TXT, NS, CAA and SOA, resolved in parallel.
```

### `email_security`

- 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
Email authentication for a domain: SPF and DMARC records, and DKIM keys found by probing about
    29 common selectors (Google, Microsoft 365, Mailchimp, SendGrid and others). Custom selectors
    may not be found.
```

### `ssl_certificate`

- 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 certificate a domain serves on port 443, from a live TLS handshake: issuer, subject,
    valid_from, valid_to, days_until_expiry, SANs, signature algorithm and serial number.
```

### `subdomains`

- 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
Subdomains of a domain from certificate transparency logs, passive DNS and DNS brute force.
    `live` lists hosts that resolve now, each with its IP; `subdomains` lists every name found, live
    first; `pools` summarises large shared-infrastructure zones. The first lookup of a domain is a fast
    snapshot and later ones are fuller; set wait=true to wait for every source (up to about 20 s).
```

## Only reads (2)

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

### `domain_lookup`

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

Description, as the server wrote it:

```untrusted-server-text
Full report on a domain in one call: WHOIS/RDAP registration, DNS records, live SSL
    certificate, subdomains (live hosts with IPs first) and email authentication (SPF, DMARC, DKIM).
    Use it to triage a suspicious domain or profile a company's domain. If one section fails it comes
    back as an object with an `error` field and the rest is unaffected. Set wait=true to wait for every
    subdomain source (up to about 20 s) instead of the fast first result.
```

### `whois_lookup`

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

Description, as the server wrote it:

```untrusted-server-text
Registration data for a domain: registrar, created, updated and expiry dates, nameservers and
    status. RDAP first (rdap.org, IANA bootstrap, 22 fallback servers), then port-43 WHOIS for 60+
    TLDs. `_source` says which one answered. Use it for domain age, expiry or registrar checks.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `domain-intelligence`:

```json
{
  "permissions": {
    "allow": [
      "mcp__domain-intelligence__domain_lookup",
      "mcp__domain-intelligence__whois_lookup"
    ],
    "ask": [
      "mcp__domain-intelligence__dns_records",
      "mcp__domain-intelligence__ssl_certificate",
      "mcp__domain-intelligence__subdomains",
      "mcp__domain-intelligence__email_security"
    ],
    "deny": []
  }
}
```
