## Findings

- **warn** Annotations that disagree with the tool in `calculate_materials` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "calculate_materials" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "run": a word for a change.
```


## Changes things (1)

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

### `calculate_materials`

- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Runs one of the website calculators for an area in square metres and returns the material list: items, quantities, unit prices and amounts before VAT, subtotal, 7% VAT and total, plus the matching website product for each line. Choices not given use the calculator defaults; the result lists the choices the customer can change. Nothing is saved or ordered.
```

## Only reads (4)

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

### `get_product`

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

Description, as the server wrote it:

```untrusted-server-text
Full public details of one product: dimensions, attributes, and each option (variation) with its SKU, price before VAT and stock. Give exactly one of sku or url.
```

### `list_calculators`

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

Description, as the server wrote it:

```untrusted-server-text
The material calculators on furringline.com (ceilings, partition walls, insulation). Use a key with calculate_materials.
```

### `list_categories`

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

Description, as the server wrote it:

```untrusted-server-text
All public product categories with slug, parent slug, product count and URL.
```

### `search_products`

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

Description, as the server wrote it:

```untrusted-server-text
Search the public FURRINGLINE catalog by words (Thai or English, all words must match) or SKU, optionally within a category. Returns name, SKU, URL, image, category, brand, price before VAT and stock. Max 20 per page, 10 pages.
```
