Available components
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 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 Management0
- Stability check failed: schema churn in the 11 days we've observed: 0 tool removals, 2 breaking changes, 0 auth/transport breaks, 0 additions. See how to fix → Fail
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
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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-… |

| paperSize | string | – | Paper size: 'Auto' (default) leaves the page to the document's own CSS — an @page rule such as '@page { size: A5 landscape; }' decides, and when the document says nothing you get A4 portrait (EU-firs… |

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 |
|---|---|---|---|
| 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… |
