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 Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- 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 Usability80
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 498 tokens (~124/item across 4 items; 4 tools + 0 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
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

check_sponsor_license Check Sponsorship Licence ~212
Check whether a company holds a UK or Netherlands work-visa sponsorship licence. The register lists official registered legal entity names, not brand, product, or trading names. If the user provides a brand name, product name, or website, first determine the company's registered legal name (via web search, the company's own website, or the relevant companies register) and pass that. Tolerates minor typos but not brand-vs-legal-name mismatches. Returns licence routes, ratings, locations and register dates. If results are ambiguous or none are found, refine the legal name and try again. For exploring or filtering many companies, use search_sponsors instead.
| Name | Type | Req | Description |
|---|---|---|---|
| company_name | string | yes | The company's registered legal entity name — not a brand, product, or trading name, and not a URL. If the user gave a brand name or website, resolve the official registered legal name first, then pas… |
| country | string | — | Which register to check: uk, nl, or both |
