## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-09.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 1 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 49/100
  - 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 283 tokens (~94/item across 3 items; 1 tools + 2 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.
  - Supports UI / widget rendering.

### `check_domain` (~271 tokens)

Check whether a domain name is registered, using real-time RDAP data
(the IETF-standardized successor to WHOIS). Use for "is domain-x.com
available/registered", "who is domain-x.com registered with", or "when
does domain-x.com expire" style questions.

\`domain` is a bare domain like "example.com" -- no protocol prefix, no
path, no spaces.

If the domain is NOT registered, returns `{"domain": ..., "registered":
false}` -- this is a normal, meaningful answer (the domain is
available), not an error.

If the domain IS registered, returns `{"domain", "registered": true,
"status", "registered_date", "expiration_date", "last_changed_date",
"registrar"}`. `status` is a list of RDAP status codes (e.g. "active",
"client transfer prohibited"). Dates are ISO 8601. `registrar` is the
registrar's name, or null if the registry redacts it for privacy.

For obviously malformed input (not a domain -- e.g. missing a dot, has
spaces, or includes a protocol like "https://"), returns a clean
\`{"error": ...}` instead of calling the API.

Input parameters:

- `domain` (string, required)
