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 Security51
- 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 7 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 check failed: the endpoint is reachable over plaintext HTTP. See how to fix → View diagnostics → Fail
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability79
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1280 tokens (~182/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- 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 (71% 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

check_phone_number Sprawdź numer telefonu (PL) ~194
Sprawdź reputację polskiego numeru telefonu. UŻYJ, gdy użytkownik pyta: kto dzwonił, czy numer to spam/oszustwo, czy telefon rzekomo z banku lub urzędu jest prawdziwy. Zwraca operatora z zakresów UKE (z notą o przenośności MNP), etykietę ryzyka z opinii, status w wykazie DNO UKE (połączenie przychodzące z numeru DNO jest sfałszowane — spoofing), wpis z Białej Listy oficjalnych infolinii i liczniki zgłoszeń. Dane: numertel.pl.

Przyjmuje pojedynczą domenę, URL, e-mail, numer lub CAŁĄ treść wiadomości (rozpoznaje zapisy evil[.]pl, hxxp:// i +48). Werdykt deterministyczny, zero LLM. Dane: numertel.pl.
