## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `photo_size_advice`

- 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
Size and price advice for a custom paint by numbers kit made from the customer's own photo, using the same rules as the photo tool on nummerschilderen.com. Use when someone asks whether their photo is suitable, which canvas size fits, or what a kit of their own photo costs. Takes the photo's width and height in pixels (or a photo the user explicitly provides, of which only the file header is read). Returns the recommended size, alternatives, the share of the photo that is cropped and the live price per size. Measures resolution and aspect ratio only, not sharpness or lighting. Formaat- en prijsadvies voor schilderen op nummer van een eigen foto.
```

## Only reads (2)

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

### `search_products`

- The name "search_products" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Searches the live catalogue of Nummerschilderen.com for paint by numbers kits by subject or keyword (dog, flowers, a city, Christmas) and price range. Use when someone looks for a ready-made paint by numbers kit or a gift. Returns products with current price, stock status and a link to the product page. Doorzoekt de webwinkel van Nummerschilderen.com op onderwerp en budget, met actuele prijs, voorraad en link.
```

### `shop_info`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the current text of Nummerschilderen.com's own pages about delivery and shipping, returns and cancellation, frequently asked questions and contact, with the page link, or where to look up the status of an order. Use for questions about ordering from this shop. Cannot look up or change individual orders. Levering, retour, veelgestelde vragen, contact en bestelstatus van Nummerschilderen.com, live van de site.
```
