## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `forecast_as_issued`

- 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
Archived JMA prefectural weather forecast as issued. Give an area and at (forecast in effect then) or issued_at (exact JMA issue time). Returns JMA's bulletin as published (Japanese weather text, wind, waves, 6-hour rain probability, temperatures) with report_datetime (JMA's issue time) apart from fetched_at (ours). Status found, not_archived (before this archive started), unknown or no_issuance_at_that_time. Not the current forecast: check JMA.
```

### `forecast_issuances`

- 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
Which prefectural weather forecasts did JMA issue for an area between two times? Lists each archived issuance (JMA issue time, transmission time, our fetch time, scheduled/unscheduled/correction/cancellation, bulletin URL and SHA-256) with coverage gaps where JMA's feed could not be read. Free window: last 30 days (an earlier since is clamped; see history_window). Use forecast_as_issued for the content. An archive, not a forecast service.
```

## Only reads (2)

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

### `catalog`

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

Description, as the server wrote it:

```untrusted-server-text
List the tools of this server with prices, data sources, licensing, daily limits and data freshness.
```

### `get_receipt`

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

Description, as the server wrote it:

```untrusted-server-text
Re-fetch the stored result of a settled paid call by its receipt_id, for when the response was lost after payment. Free. Unknown or unsettled receipt ids return RECEIPT_NOT_FOUND. Results are kept for 90 days after settlement.
```
