## Findings

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

```untrusted-server-text
The server marks "get_cashback_link" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "get_cashback_link" says "get": a word for reading.
```


## Changes things (2)

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

### `calculate_cashback`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Work out the cashback on a purchase: commission = price × commission rate, of which the buyer receives a share set by their CashbackPro level (Bronze 30%, Silver 45%, Gold 60%, Platinum 80%). Returns the figure for every level. Pure calculation — nothing is looked up.
```

### `get_cashback_link`

- The name "get_cashback_link" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Return the CashbackPro purchase link for an AliExpress product. These are affiliate links: with a connected CashbackPro account (extension token in the Authorization Bearer header, obtained at https://cashbackpro.org/connect-extension?utm_source=mcp) part of the commission goes back to the buyer as cashback; without one the link still works but pays none. Which case applies is stated in the response, along with the disclosure text to pass on to the user.
```

## Only reads (3)

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

### `get_product_details`

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

Description, as the server wrote it:

```untrusted-server-text
Look up one AliExpress product by its numeric ID: authoritative price, rating, sales volume, commission rate and category, plus what the cashback would come to at each CashbackPro level.
```

### `get_promo_codes`

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

Description, as the server wrote it:

```untrusted-server-text
AliExpress promo codes currently active on the global (USD) site: platform-wide codes and product-specific ones, with minimum spend, remaining quantity and expiry. Expired codes are excluded and the set refreshes daily. Codes stack with cashback, so a code and a CashbackPro link apply to the same purchase.
```

### `search_products`

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

Description, as the server wrote it:

```untrusted-server-text
Search the AliExpress catalogue and return compact product cards with price, rating, sales volume and the affiliate commission rate — the data needed to judge what a product actually costs. Low-quality listings are filtered out automatically (blocked categories, minimum price). Product URLs in the result are CashbackPro affiliate links.
```
