**6 tools: 1 change things and 5 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 1 | ask |
| Only reads | read | 5 | allow |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "create_cart_link" says "create": a word for a change.
```


## Changes things (1)

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

### `create_cart_link`

- The name "create_cart_link" says "create": 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
Собрать корзину из найденных товаров и получить одну ссылку: покупатель открывает её и видит готовую корзину на mpshop.su. До 20 позиций. Ничего не заказывает и не оплачивает — только формирует ссылку.
```

## Only reads (5)

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
Полная информация о конкретном товаре: цена, штрихкод, артикул, бренд, путь категории, ссылка на карточку и остаток по каждому магазину сети. Ищет по product_id (из search_products) либо по штрихкоду EAN.
```

### `list_brands`

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

Description, as the server wrote it:

```untrusted-server-text
Бренды, представленные в магазине. Без параметров — весь список; с query — только подходящие по подстроке. Полезно, чтобы уточнить точное написание бренда перед поиском.
```

### `list_categories`

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

Description, as the server wrote it:

```untrusted-server-text
Разделы каталога. Без параметров — верхний уровень; передайте parent, чтобы получить подразделы. Используйте, когда нужно сузить поиск, а точное название категории неизвестно.
```

### `list_stores`

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

Description, as the server wrote it:

```untrusted-server-text
Адреса, часы работы и координаты магазинов сети «МылоПорошок» в Махачкале. store_id из этого списка совпадает с идентификатором в остатках товара.
```

### `search_products`

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

Description, as the server wrote it:

```untrusted-server-text
Найти товары в каталоге магазина бытовой химии и косметики «МылоПорошок» (Махачкала). Ищет по названию и синонимам, поэтому «гарнье» находит товары GARNIER. Можно сузить по категории, бренду и цене. По умолчанию отдаёт только то, что есть в наличии в магазинах сети. Возвращает название, бренд, цену в рублях, остаток, ссылку на карточку и фото.
```
