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 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 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 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 Usability66

AI-judged instruction clarity (good).Pass
Tool/resource definitions use about 424 tokens (~60/item across 7 items; 7 tools + 0 resources), lean.Pass
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management17

Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage93

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
80% of tool parameters carry a description.Partial

Capabilities100

Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
