| --- | --- | --- |
| 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

No check matched anything in these tool definitions.


## Only reads (4)

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

### `compare_alternatives`

- The name "compare_alternatives" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Given an Avahit product id, return ranked alternatives with a match percentage explaining how close each one is (same category, price distance, product type, same store).
```

### `get_price_history`

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

Description, as the server wrote it:

```untrusted-server-text
Given an Avahit product id, return what Avahit itself observed about its price: current price and when it was last verified against the store, the lowest and highest price seen with dates, the average, how many checks and since when. Amazon products have no history — Amazon's license forbids keeping their prices longer than 24 hours.
```

### `get_store_sales`

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

Description, as the server wrote it:

```untrusted-server-text
When does a brand store have sales? Given a store domain or brand name (e.g. 'glossier.com', 'Boll & Branch'), return the sales it announced on its homepage or by email to newsletter subscribers with dates, whether product prices actually dropped in each (or the discount came off at checkout), price cuts Avahit measured itself, today's homepage offer, holiday sale pages (Black Friday) and how often sold-out items come back. Promo codes are never included.
```

### `search_products`

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

Description, as the server wrote it:

```untrusted-server-text
Search Avahit's catalog of direct-to-consumer brand products whose prices Avahit re-checks at the store every day. Returns title, current price with the date of the last check, store domain, store rating and a link to the product page on Avahit.
```

## Claude Code permissions
