## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `html_to_pdf`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use to produce a real, full-quality PDF from HTML (reports, receipts, letters). Inputs: "html" (required), "format" (A4|Letter|Legal|A3|A5), "landscape", "margin" (CSS length), "filename". Rendered by headless Chromium with JavaScript disabled; only data: URIs and public https assets load; Chinese text supported. Output: the PDF as an embedded base64 resource plus pages, bytes and remaining quota. Requires "Authorization: Bearer <key>" (or "sandbox" for a watermarked 1-page trial, 5/day). Without a usable key it returns a 402 payment_required result with buy links. Cost: 1 document from your monthly plan (free key: 100/month), or 1 prepaid credit after the cap.
```

### `render_template`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use when you have structured data for an invoice or travel itinerary and want a clean PDF without writing HTML. Inputs: "template" ("invoice": seller, buyer, items, tax_rate, currency; "itinerary": trip, days), "data" (object; full examples at GET https://rendlet.com/v1/templates), "filename". Output: the PDF as an embedded base64 resource plus pages and remaining quota. Same auth and 402 behaviour as html_to_pdf. Cost: 1 document from your monthly plan, or 1 prepaid credit after the cap.
```

## Only reads (3)

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

### `get_pricing`

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

Description, as the server wrote it:

```untrusted-server-text
Use when the user asks about price, hits a quota, or needs more documents. Inputs: none. Output: JSON with the free key, monthly plans with Stripe links, prepaid credit packs with Stripe Payment Links, the USDC-on-Base purchase endpoint and steps, and the cost of each tool. Cost: free, no key.
```

### `list_capabilities`

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

Description, as the server wrote it:

```untrusted-server-text
Use first to learn what Rendlet can render and which tools are free. Inputs: none. Output: JSON listing tools, input modes (HTML, built-in invoice/itinerary templates), page sizes, limits per plan, auth method and links. Cost: free, no key.
```

### `preview_pdf`

- The name "preview_pdf" says "preview": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use to show what a document will look like before paying or signing up. Inputs: optional "html" (string, up to 50 KB; omit to preview the built-in sample invoice). Output: a 1-page low-resolution, PREVIEW-watermarked PDF (rasterized first A4 page) as an embedded base64 resource. Not for production use. Cost: free, no key, 3 previews per IP per day.
```
