## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `buy_topup`

- The name "buy_topup" says "topup": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Purchase a top-up data package for an existing eSIM. Returns a Stripe checkout URL.
```

## Changes things (2)

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

### `check_data_balance`

- 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 remaining data balance on an eSIM. Requires a session key and the eSIM's ICCID.
```

### `create_order`

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

Description, as the server wrote it:

```untrusted-server-text
Create an order for an eSIM package. Returns a Stripe checkout URL where the user can pay. Requires a session key (from a previous tool call's structuredContent) or creates one automatically.
```

## Only reads (6)

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

### `check_order_status`

- The name "check_order_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Check the status of the most recent order. Requires a session key from a previous tool call.
```

### `get_business_context`

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

```

Search for eSIM data packages by country. Returns up to 10 packages per page sorted by price. Use the page parameter to paginate. No auth required. Call get_business_context first to understand IP routing and package types.

Package types:
- "regular": Fixed data pool (e.g. 3GB for 30 days). Best for most travelers.
- "daily": Data resets each day (e.g. 2GB/day for 5 days). Good for short trips with predictable daily usage. Top-up days are available.

IP routing (important for Asia):
- "breakout": Local IP in destination country. Best for streaming, banking, social media. ALWAYS recommend by default.
