## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `countries`

- 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
The 30 country codes, names and last read time.
```

### `cross_country_trends`

- 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
Topics trending right now in 2+ of the 30 countries, most countries first.
```

### `trending_day`

- 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.

```untrusted-server-text
Every trending search seen on one UTC day (today or the last 30 days) for 1-5 countries, biggest first, with first/last seen, peak traffic and news.
```

### `trending_now`

- 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
Newest Google trending searches for 1-5 countries (ISO-2 codes): query, approximate traffic, start time, first seen today, other countries where it trends, news links.
```

## Only reads (1)

### `topic_history`

- The description's first verb is "search": a word for reading.

```untrusted-server-text
Search the last 30 days of trending searches for a topic; returns each matching search with the countries, first seen, last day seen and peak traffic.
```
