## Findings

No check matched anything in these tool definitions.


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `render_html_to_pdf`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `render_template_to_pdf`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
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).
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `get_starter`

- The name "get_starter" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `list_starters`

- The name "list_starters" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Claude Code permissions
