## Trust breakdown
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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)
Scored 2026-08-22.
- **Endpoint Security**: 57/100
- The endpoint's TLS certificate is valid, in date, and uses a strong key.
- Authorisation not fully verified: no authorisation is required to call this server, and 2 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
- HTTPS is enforced; there's no plaintext access path.
- HSTS check failed: the Strict-Transport-Security header is absent.
- DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
- Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 29/100
- 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
- AI-judged instruction clarity (good).
- Context-footprint check failed: tool/resource definitions use about 1795 tokens (~598/item across 3 items; 2 tools + 1 resources), over budget; trim descriptions and params.
- Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
- Stability check failed: schema churn in the 11 days we've observed: 0 tool removals, 2 breaking changes, 0 auth/transport breaks, 0 additions.
- **Tool Coverage**: 100/100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).
- 100% of tool parameters carry a description.
- **Capabilities**: 100/100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (2)
### `html_to_pdf_wk` (~680 tokens)
Convert HTML to PDF using the wkhtmltopdf rendering engine. Supports JavaScript execution and screen-capture style rendering. Good for simple documents, web page snapshots, layouts that rely on JavaScript, and **fillable PDF forms** (set pdfForms to true). Available on all PdfBroker.io plans including the free tier. Does NOT support PDF/A or PDF/UA compliance — use html_to_pdf for compliant documents. Does NOT honour CSS '@page { size: ... }' — page geometry comes from paperSize and orientation; use html_to_pdf when the document's own stylesheet must decide. EU-first defaults: A4 paper, Portrait orientation.
Input parameters:
- `extraArguments` (object|null): Optional extra wkhtmltopdf engine arguments forwarded verbatim to the engine. Keys are CLI long-form options without '--'. For switch-style flags use an empty-string value — example: {"enable-forms":…
- `html` (string|null): HTML content to convert. Can be a full document or a fragment. Optional if 'url' is supplied instead — pass exactly one of the two.
- `orientation` (string): Page orientation: 'Auto' (default, engine default is Portrait), 'Portrait' or 'Landscape'.
- `paperSize` (string): Paper size: 'Auto' (default) leaves it to the engine, which uses A4 (EU-first default). Name a size to set it explicitly: 'A4', 'Letter', 'A3', 'Legal'. Note that wkhtmltopdf does NOT honour CSS '@pa…
- `pdfForms` (boolean): Set to true to produce a fillable PDF: the document's ,
