## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `simpleanalytics_export_datapoints`

- 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
Raw, unsampled page views or events of one website for a date range, as rows with only the fields asked for. The reply is capped at max_rows (default 100, max 1000) rows and 2 MB; "truncated" says more exist, so narrow the range. Rows are cut to about 40 000 characters of JSON. Dates: YYYY-MM-DD, or YYYY-MM-DDTHH for one hour (start and end the same day). Robots are left out unless asked. Needs the user id too. Export API: GET /api/export/datapoints.
```

## Only reads (5)

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

### `simpleanalytics_get_breakdown`

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

Description, as the server wrote it:

```untrusted-server-text
Top values of one dimension for one website and date range, each with pageviews and visitors: pages, countries, referrers, UTM sources/mediums/campaigns/contents/terms, browsers, operating systems or device types. Optional filters as in simpleanalytics_get_stats. Stats API: GET /<hostname>.json?fields=<dimension>.
```

### `simpleanalytics_get_events`

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

Description, as the server wrote it:

```untrusted-server-text
How often custom events happened on one website in a date range. Pass event names, or leave names out for all events (up to 1000). Stats API: GET /<hostname>.json?events=...
```

### `simpleanalytics_get_stats`

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

Description, as the server wrote it:

```untrusted-server-text
Aggregated traffic for one website and date range: total pageviews, unique visitors and the median seconds on page. Optional filters narrow it to a page, country, referrer, UTM value, browser, OS, device or metadata value. Stats API: GET /<hostname>.json.
```

### `simpleanalytics_get_timeseries`

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

```

### `simpleanalytics_list_websites`

- The name "simpleanalytics_list_websites" says "list": a word for reading.
