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 Security63

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 not yet verified: we couldn't determine whether a plaintext access path exists. 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 & Reachability100

Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

Schema Quality & AI Usability55

AI-judged instruction clarity (good).Pass
Context-footprint check failed: tool/resource definitions use about 863 tokens (~172/item across 5 items; 5 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 Coverage89

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
67% of tool parameters carry a description.Partial

Capabilities100

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