## Findings

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

```untrusted-server-text
The server marks "check_stack" 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 "add": a word for a change.
```

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

```untrusted-server-text
The server marks "compare_products" 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 name "compare_products" says "compare": a word for reading.
```


## Changes things (2)

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

### `check_stack`

- The description's first verb is "add": 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
Adds up each ingredient across several products taken together (up to 12) and compares each daily total with the adult upper limit of the country, with the same rules engine as the Verateca site. For every ingredient: total per day, applicable limit, share of the limit, status ("within the upper limit", "over the upper limit", "no upper limit set" or "not compared"), the products that contribute, and duplicates across products. Limits of other countries follow. Interactions with medicines are not checked.
```

### `compare_products`

- The name "compare_products" says "compare": a word for reading.
- The description's first verb is "put": 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
Puts 2 to 6 published products side by side: daily dose, price per day where published, and for each ingredient the daily amount and its share of the applicable upper limit of the country.
```

## Only reads (4)

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

### `get_ingredient`

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

Description, as the server wrote it:

```untrusted-server-text
Returns one substance of the register: its forms with the share of the element where known, the upper limit of the country first, then the limits of other countries with type, source and the date checked, reference sources, and the number of published products that contain it.
```

### `get_product`

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

Description, as the server wrote it:

```untrusted-server-text
Returns one published product record: composition as the label states it, daily amounts, the applicable upper limit of the country for each ingredient with its share, limits of other countries, the status in the country, prices per day where published, and the dates of each part.
```

### `get_selection_link`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the address of the Verateca order page for one of its three paid services (quick, full, review), with the price and currency the site shows for the country and a one-line description. The tool takes no payment and creates no order; the order page asks its own questions and takes payment there.
```

### `search_products`

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

Description, as the server wrote it:

```untrusted-server-text
Searches the Verateca register of dietary supplements by product name, brand, ingredient or barcode. Returns up to 10 published products with id, brand, form, page address, lowest price per day where prices are published, number of offers and the date the record was checked. Results are ordered by match, never by payment.
```
