## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_fit`

- 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
Whether one product fits one vehicle: 'yes' with the fit options and the price and page for the vehicle, 'not listed', or 'by what it mounts to' for carriers. Also what the product needs (crossbars, a hitch, required parts) and what checkout will ask. The product is its rackwarehouse.com page URL, its handle or its SKU.
```

### `what_fits`

- 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
What fits one vehicle. Without a category: how many products fit, by category, and the category handles to ask with. With a category: up to eight products, each with its fit for this vehicle, its price for this vehicle and its page; carriers that mount to crossbars or a hitch come back with what they mount to and the base racks for the vehicle.
```

## Only reads (3)

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

### `find_vehicle`

- The name "find_vehicle" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Turn the shopper's words ('2019 tacoma', 'subaru outback') into vehicles Rack Warehouse has fitment for, with the roof types each can have. Use the make and model it returns with the other tools.
```

### `get_product`

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

Description, as the server wrote it:

```untrusted-server-text
One product as its page shows it: price and sale, availability, variants, specs, summary and highlights, what a rack system includes, what it mounts to, required products, what checkout asks, rating and reviews, and its page. It does not list vehicles: use check_fit for one.
```

### `search_products`

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

Description, as the server wrote it:

```untrusted-server-text
Search Rack Warehouse's catalog the way the site's search box does: up to eight products for the shopper's words, optionally within a category, a brand and a price ceiling, each with its price, review count, how it fits (by vehicle, or by what it mounts to) and its page.
```
