Trust breakdown (6 categories)

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 Security46

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 connect, but we couldn't read the tool list to see what that exposes. View diagnostics → Unverified
HTTPS enforcement could not be verified: the plaintext port answered with HTTP 410, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
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 & Reachability0

Transport check failed: declared streamable-http, but the endpoint returned HTTP 410. See how to fix → View diagnostics → Fail

Schema Quality & AI Usability0

Schema not yet verified: we couldn't read the endpoint's schema.Unverified
