## Findings

No check matched anything in these tool definitions.


## Changes things (5)

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

### `domain_intel`

- 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
Registration intelligence for a domain via RDAP (the modern WHOIS). Returns registrar, creation/expiration/last-changed dates, domain age in years, EPP status codes, nameservers, DNSSEC state, and abuse contact. Use to vet a company, assess a lead, or judge how established a domain is.
```

### `domain_report`

- 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
One-call full dossier on a domain: registration (RDAP), DNS records, email deliverability, and website tech stack, combined into a single report. Use for fast lead qualification, company research, or recon without four separate calls.
```

### `email_deliverability`

- 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
Assess whether a domain (or the domain of an email address) can receive mail and how strong its sender authentication is. Returns MX presence, SPF and DMARC policy, whether it's a free consumer provider (gmail, etc.) or a known disposable/temp-mail provider, and an overall verdict. Use to qualify leads and flag throwaway signups.
```

### `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
Discover a domain's public subdomains (app., api., staging., and so on) from Certificate Transparency logs, querying crt.sh and Cert Spotter in parallel and returning whichever answers first. Useful for mapping a company's public attack surface or infrastructure. If both sources are down the call returns an error rather than an empty list.
```

### `tech_stack`

- 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
Fingerprint the technology behind a website by fetching its homepage. Detects web server, CMS/framework (WordPress, Shopify, Next.js, etc.), CDN, analytics, and returns the page title, final URL after redirects, and key response headers. Use for competitive research and lead enrichment.
```

## Only reads (1)

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

### `dns_lookup`

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

Description, as the server wrote it:

```untrusted-server-text
Look up DNS records for a domain via Cloudflare DNS-over-HTTPS. Returns A, AAAA, MX, NS, TXT, CNAME, and SOA records. Use to see where a domain is hosted, who runs its mail and DNS, and what verification/policy TXT records it publishes.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__domain-dns-whois__dns_lookup"
    ],
    "ask": [
      "mcp__domain-dns-whois__domain_report",
      "mcp__domain-dns-whois__domain_intel",
      "mcp__domain-dns-whois__email_deliverability",
      "mcp__domain-dns-whois__tech_stack",
      "mcp__domain-dns-whois__subdomains"
    ],
    "deny": []
  }
}
```
