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 not fully verified: no authorisation is required to call this server, and 1 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
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 Usability57

AI-judged instruction clarity (fair).Partial
Tool/resource definitions use about 126 tokens (~126/item across 1 items; 1 tools + 0 resources), lean.Pass
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management10

Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage71

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
0% of tool parameters carry a description.Fail
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

Changelog

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

2 Aug 26 +1

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

MCP tools — 1 exposed · ~126 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.

Tool Tokens

render_html_to_pdf ~126

Render an HTML document to a PDF, returned base64-encoded. `html` is a complete HTML string. Inline any images, fonts and CSS as `data:` URIs — external http(s) resources are not fetched, and no JavaScript is executed (HTML + CSS only). Returns `{"pdf_base64": "<base64-encoded PDF>", "pages": <page count>}`. Costs one credit. For documents larger than 256 KB, use the REST API (`POST /v1/render`).
