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 Security46
- 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 4 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 not yet verified: we couldn't determine whether a plaintext access path exists. View diagnostics → Unverified
- 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 Usability62
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1076 tokens (~269/item across 4 items; 4 tools + 0 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 Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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
Capabilities20
- Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail

get_starter ~121
Fetch the full HTML body, CSS, sampleData, and pageOptions for one starter template by slug. Use this when you need to understand the exact shape of `data` the template expects before calling render_template_to_pdf, or when you want to fork a starter into custom HTML. Free, no payment, no auth required.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | The starter slug. Examples: "invoice", "receipt", "certificate", "contract", "nda", "boarding-pass", "menu". Call list_starters to discover all 45 slugs. |
No output schema declared.
No examples provided.
list_starters ~121
List pdfzen's 45 public starter templates — invoices, receipts, contracts, certificates, NDAs, letters, reports, resumes, boarding passes, menus, bank statements, lab reports, lease agreements, performance reviews, and more. Returns an array of { slug, name, description, icon, pageOptions, fonts, dataKeys }. Free, no payment, no auth required. Call this first to discover what fits the user request, then optionally call get_starter to see the expected data shape, then call render_template_to_pdf to produce the PDF.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
render_html_to_pdf ~287
Prepare a paid PDF render from arbitrary Handlebars-flavoured HTML. Use only when no starter fits (one-off layouts, custom branding). Prefer render_template_to_pdf when a starter matches. Validates your HTML and returns the exact, ready-to-execute HTTP request to run against pdfzen's render endpoint — POST /v402/render/pdf (x402, $0.006 USDC on Base, no API key) or POST /v1/render/pdf (pdfzen API key). pdfzen renders are executed over HTTP, not streamed in-band over MCP; this tool is the bridge.
| Name | Type | Req | Description |
|---|---|---|---|
| css | string | — | Optional CSS injected into the document head. Alternative to inline <style> in `html`. |
| data | object | — | Handlebars context object resolved against the {{...}} expressions in `html`. |
| html | string | yes | The HTML body. Supports Handlebars {{ }} expressions resolved against `data`, plus pdfzen helpers ({{barChart}}, {{lineChart}}, {{pageBreak}}, {{#each}}, {{#if eq}}). Don't include <html>/<head>; jus… |
| pageOptions | object | — | Page format/margin/orientation. Defaults to A4 portrait. Example: { "format": "A4", "margin": { "top": "20mm" } }. |
No output schema declared.
No examples provided.
render_template_to_pdf ~294
Prepare a paid PDF render from one of the 45 starter templates. Validates your template + data and returns the exact, ready-to-execute HTTP request to run against pdfzen's render endpoint — POST /v402/render/pdf (x402, $0.006 USDC on Base, no API key) or POST /v1/render/pdf (pdfzen API key, credit-billed). pdfzen renders are executed over HTTP, not streamed in-band over MCP; this tool is the bridge. Your `data` is merged ON TOP of the starter sampleData at render time, so partial payloads inherit demo defaults (e.g. ship just the customer name + total).
| Name | Type | Req | Description |
|---|---|---|---|
| data | object | — | Handlebars context. Each starter expects a specific shape — call get_starter to see the sampleData and dataKeys for the chosen slug. Your fields merge ON TOP of sampleData, so you can supply only the… |
| pageOptions | object | — | Page format/margin/orientation overrides. Defaults come from the starter (most are A4 portrait). Example: { "format": "Letter", "landscape": true }. |
| template | string | yes | Slug of the starter to render (e.g. "invoice", "receipt", "certificate"). Call list_starters first if unsure which fits the user request. |
