## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `create_checkout_link`

- The name "create_checkout_link" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a secure payment link on siima.online for a Siima eSIM plan (Stripe-powered, but hosted on our own site — never a redirect to checkout.stripe.com). Give the returned url to the user to complete payment. Optionally pass the buyer's email to pre-fill the checkout form. The buyer confirms it with a 6-digit code we email them, then pays — nothing is ordered until they do. After payment the buyer is emailed a link to their eSIM within a minute; opening it on their phone gives a one-tap install, the QR code and manual installation codes. No account or signup is required.
```

## Only reads (4)

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

### `get_esim_plan`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch full details of a single Siima eSIM plan by its id (from search_esim_plans). To buy: call create_checkout_link with the plan id, give the returned URL to the user. They confirm their email with a 6-digit code and pay there; nothing is ordered until they do. After payment they are emailed a link to their eSIM; opening it on their phone gives a one-tap install, the QR code and manual codes. No account needed.
```

### `list_destinations`

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

Description, as the server wrote it:

```untrusted-server-text
List all countries Siima sells a single-country eSIM plan for, with plan counts and the cheapest total price per country. Country codes are ISO 3166-1 alpha-2. Counts and prices cover country plans only, so they stay comparable — many more countries are reachable via multi-country plans; call list_regions for those.
```

### `list_regions`

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

Description, as the server wrote it:

```untrusted-server-text
List every multi-country coverage area Siima sells — regional areas such as "Europe+", "South East Asia" or "CENAM", and worldwide plans — with the countries every plan in it covers, how many plans it has, and its cheapest total price. Use this for a trip crossing several countries: pick a coverage area whose `countries` list contains the whole itinerary, then pass its name as `coverage` to search_esim_plans. `countries_on_some_plans` lists countries only some of the area's plans include — if the itinerary needs one, confirm the chosen plan covers it with get_esim_plan before buying. For a single-country trip use list_destinations instead.
```

### `search_esim_plans`

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

Description, as the server wrote it:

```untrusted-server-text
Search prepaid travel eSIM data plans by destination country (ISO 3166-1 alpha-2, e.g. "JP"), region (e.g. "Europe"), minimum data in GB, maximum total price, or plan duration in days. Plans come in three coverage types: "country" (one country), "regional" (a named multi-country area such as "Europe+" or "South East Asia"), and "global" (worldwide). A country filter matches every plan that covers it, of any coverage type — so searching country="FR" returns France-only plans alongside the Europe and worldwide plans that include France. For a trip through several countries, filter coverage_type="regional" or "global" to get one eSIM for the whole route; for a single-country trip a "country" plan is usually cheapest. Returned price is the final amount the customer pays at checkout (all fees included), in the requested currency. To buy: call create_checkout_link with the plan id, give the returned URL to the user. They confirm their email with a 6-digit code and pay there; nothing is ordered until they do. After payment they are emailed a link to their eSIM; opening it on their phone gives a one-tap install, the QR code and manual codes. No account needed.
```
