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
Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (publish_markdown_to_harness). See how to fix → View diagnostics → Fail
HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
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 Usability60

AI-judged instruction clarity (fair).Partial
Tool/resource definitions use about 757 tokens (~63/item across 12 items; 12 tools + 0 resources), lean.Pass
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management23

Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage82

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
36% of tool parameters carry a description.Partial
Structured output schemas are declared (100% 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

MCP tools — 12 exposed · ~757 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
