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 → Why this is hard to score →
Endpoint Security57
- 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 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. 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 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 Usability29
- 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Fail
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
html_to_pdf ~1,108
Convert HTML and CSS to a PDF document using the WeasyPrint rendering engine. Supports every PDF/A archival level, PDF/UA accessibility and the PDF/X print standards. Best for professional documents: invoices, reports, certificates, contracts, and accessible documents. Also produces **fillable PDF forms** — set pdfForms to true. Send a complete HTML document including <html>, <head> with <style>, and <body> tags. Page geometry comes from the document's own CSS @page rule unless paperSize or orientation is set explicitly. Returns a temporary download URL for the generated PDF (valid for 30 minutes). Requires a paid PdfBroker.io plan (Starter or above). EU-first defaults: A4 paper, Portrait orientation when neither the document nor the caller says otherwise.
| Name | Type | Req | Description |
|---|---|---|---|
| conformanceLevel | string | – | PDF compliance standard. 'None' (default) requests no conformance. Archival, level B — visual fidelity: 'PdfA1b' (widest compatibility), 'PdfA2b', 'PdfA3b' (allows embedded attachments, used for e-in… |
| extraArguments | object|null | – | Optional extra WeasyPrint engine arguments forwarded verbatim to the engine. Keys are CLI long-form options without '--'. For switch-style flags use an empty-string value — example: {"presentational-… |

html_to_pdf_wk ~680
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.
| Name | Type | Req | Description |
|---|---|---|---|

| 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… |
