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 Security60

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 6 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 is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass

Transport & Reachability100

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

Schema Quality & AI Usability76

100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
AI-judged instruction clarity (good).Pass
Context-footprint check failed: tool/resource definitions use about 828 tokens (~118/item across 7 items; 6 tools + 1 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 Management7

Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage90

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
65% of tool parameters carry a description.Partial
Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass

Capabilities100

Implements a current MCP spec version (2026-07-28).Pass
Supports UI / widget rendering.Pass
