## Findings

No check matched anything in these tool definitions.


## Only reads (3)

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

### `get_buy_link`

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

Description, as the server wrote it:

```untrusted-server-text
Get a simabroad.com checkout link for one eSIM plan, by the id returned from search_esim_plans. Opening the link adds that exact plan to the cart and opens checkout; the traveler pays there (card, Apple Pay or Google Pay) and gets the eSIM QR code by email. Nothing is charged by calling this tool.
```

### `list_destinations`

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

Description, as the server wrote it:

```untrusted-server-text
List countries and regions where SimAbroad sells eSIM plans right now, with the country_code to pass to search_esim_plans. Search accepts names, common aliases ('USA', 'UK') and codes. Countries marked multi_country_only are covered by regional or global plans only.
```

### `search_esim_plans`

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

Description, as the server wrote it:

```untrusted-server-text
Search SimAbroad eSIM plans for a trip. Pass country_code (ISO 2-letter, e.g. 'JP', or a code from list_destinations such as 'USPR') to get every plan that works there: single-country plans plus regional and global plans that cover it (see the coverage field). Or pass region for multi-country plans. Use min_validity_days with the trip length and min_data_gb or unlimited to match the traveler's needs. Returns only plans on sale now, cheapest first, with the USD price charged at checkout and a buy_url that opens checkout for that exact plan.
```

## Claude Code permissions
