## 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 2026-08-03.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - 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**: 76/100
  - 75% 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 304 tokens (~101/item across 3 items; 1 tools + 2 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% 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.

### `search_domains` (~179 tokens)

Search domain availability

Read-only availability and pricing lookup for specific domain names. No purchase or order is created by this tool — it only returns information. Accepts 1–200 fully-qualified domains (e.g. ['acme.com', 'acme.io']) and returns results for exactly those domains — it does NOT suggest alternative TLDs or expand the list. Each result includes whether the domain is available, whether it is a premium name, the first-year registration price, and the annual renewal price. Available results also carry a `checkout_url` the user can open in a browser to register the domain on justdomain.ai if they choose to.

Input parameters:

- `domains` (array, required): Fully-qualified domains to check, e.g. ['acme.com', 'acme.io', 'acme.ai']. Each entry must include the TLD. Maximum 200 per request.

Output parameters:

- `component_hint` (string)
- `domains` (array): The exact domains requested by the caller, echoed back.
- `error`: Set when the search could not be completed (e.g. invalid query, provider failure).
- `error_message`
- `next_action` (string)
- `results` (array)
- `warnings` (array)
