## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `identify_card_photo`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Identify a Pokemon card from a photo URL (raw card or slab, any angle): the top candidates with PokeInvest IDs, prices and population. 91% right card on 1,000 real eBay photos, 95% in the top 3. Same-art variants (1st Edition, reverse holo) cannot be told apart; show the top 3.
```

## Only reads (7)

### `get_card_prices`

```

### `get_deals`

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

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.
