## Only reads (4)

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

### `find_cheapest`

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

Description, as the server wrote it:

```untrusted-server-text
Find the cheapest supplements by normalized price-per-unit within a category (and all its subcategories). This is the primary tool for "what is the cheapest X?" questions. Use list_categories first to pick a valid category_slug.
```

### `get_product`

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

Description, as the server wrote it:

```untrusted-server-text
Get full detail for one product by its id: price, normalized unit price, size, bulk/staffel tiers, buy link, and recent price history. Use the id returned by find_cheapest or search_products.
```

### `list_categories`

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

Description, as the server wrote it:

```untrusted-server-text
List the supplement categories that currently hold priced products, each with a live product count, store count, lowest normalized unit price, and its comparison basis (per_kg / per_serving / per_capsule). Use this to discover a valid category_slug for find_cheapest.
```

### `search_products`

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

Description, as the server wrote it:

```untrusted-server-text
Search the whole supplement catalog by product name or brand. Typo-tolerant (e.g. "kreatine", "theanin" still match). Results are ordered by relevance, then cheapest normalized price-per-unit. Use find_cheapest instead when you already know the category.
```
