Available components
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. How we score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability76
- 75% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Partial
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 304 tokens (~101/item across 3 items; 1 tools + 2 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
- Supports UI / widget rendering.Pass

search_domains Search domain availability ~179
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.
| Name | Type | Req | Description |
|---|---|---|---|
| domains | array | yes | Fully-qualified domains to check, e.g. ['acme.com', 'acme.io', 'acme.ai']. Each entry must include the TLD. Maximum 200 per request. |
| Name | Type | Req | Description |
|---|---|---|---|
| component_hint | string | — | — |
| domains | array | yes | The exact domains requested by the caller, echoed back. |
| error | — | — | Set when the search could not be completed (e.g. invalid query, provider failure). |
