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

### `get_call_price`

- The name "get_call_price" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "browser": it reads web pages, which anyone can write.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Helps the person call a phone number anywhere in the world with Suparelay: returns the price per minute and a Call link that opens the Suparelay browser dialer with the number ready. Use it when the person wants to call a phone number or asks what a call to it costs. Pass the number in E.164 format with the country code, such as +33142868200. The person talks on the call in the browser; this tool does not dial.
```

- Tag untrusted-input: The description's first sentence says "browser": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Helps the person call a country with Suparelay: returns the landline and mobile prices per minute and a Call link that opens the Suparelay browser dialer. Use it when the person wants to call a country or asks what calls to it cost, without a phone number. Pass the two-letter ISO country code, such as IN. The person talks on the call in the browser; this tool does not dial.
```
