## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `batch_keyword_difficulty`

- 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
Score up to 10 keywords in one call. Cost: 10 credits per keyword.
```

## Only reads (7)

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

### `get_app_detail`

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

Description, as the server wrote it:

```untrusted-server-text
Return one app's full record. Accepts the canonical id ("apple:284882215", "google:com.spotify.music"), a bare Apple track id, an Android package name, or a pasted App Store / Google Play URL. Cost: 1 credit.
```

### `get_app_historicals`

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

### `get_app_reviews`

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

Description, as the server wrote it:

```untrusted-server-text

Live Google Play rows carry no title (Play reviews have none). Cost: 1 credit per row returned (an empty page costs 1).
```

Description, as the server wrote it:

### `search_apps`

The tool behind niche sizing, competitor shortlists, and localization-gap hunting. Cost: 1 credit per row returned (an empty page costs 1).
