## Quality 75/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description

- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 6 of 6 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 861 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 18 tool changes in 30 days
- fail `stability.rug_pull`: 1 tools kept their name but changed most of their description in 30 days; review before trusting them

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 861 tokens to load them all
- tool set hash: bf112bf4d3944536d9d60aeb47db692e
- tools last changed: 2026-10-08T15:55:11.544Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.datakoot/domain-dns-whois.svg)](https://protogrid.dev/servers/com.datakoot/domain-dns-whois)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

- 2026-10-03 `subdomains` changed (description, outputSchema) **meaning changed**
  - before: Discover subdomains of a domain from public Certificate Transparency logs (crt.sh). Useful for mapping a company's public surface (app., api., staging., etc.). Best-effort: crt.sh can be slow; returns a note if unavailable.
  - after: 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.

## Tools (6)

- `dns_lookup`: 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.
- `domain_intel`: 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`: 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`: 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`: 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`: 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.
