## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `check_availability`

- 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
Check whether a plan can be fulfilled right now for a given quantity, using the same gate the checkout runs. Returns available true/false; reason 'delisted' means the SKU left the catalog, 'unavailable' means it temporarily cannot be fulfilled.
```

## Only reads (3)

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

### `get_plan`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch full public details for a single purchasable plan by its package_code: coverage, data allowance, validity, retail price in USD cents. Errors with plan_not_found for unknown or unsellable codes.
```

### `get_quote`

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

Description, as the server wrote it:

```untrusted-server-text
Price an order (package_code, quantity, optional promo code) exactly as checkout would: returns subtotal, discount, and the final total in USD cents, plus the promo status. Purely informational — no order is created.
```

### `search_plans`

- The name "search_plans" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the purchasable travel eSIM plan catalog. Filter by destination country, region, minimum data, minimum duration, and maximum price. Returns public plan details (prices in USD cents) sorted cheapest first, with offset pagination via next_offset.
```
