The official MCP server for Quackr, a virtual phone number service for SMS verification and OTP receipt. Numbers are rented against an account balance, and the messages that land on them are read back programmatically.

- A temporary number purchased for receiving SMS, deducted from the balance
- The SMS received on a rented number
- Every currently active number on the account
