MCP Server Overview

The sv-number/mcp-server MCP server connects AI agents to the SV Number SMS-verification API over stdio. It helps agents select a country and service, order a private number, retrieve a parsed SMS verification code, and close or cancel the activation. Additional tools expose account balance, service availability, repeat SMS requests, and local RFC 6238 TOTP generation. Use it for short-lived service verification flows, not for calls, outbound SMS, or permanent phone access.

Primary Use Cases for MCP Server:
  • Order a temporary number for service verification
  • Retrieve and parse an SMS verification code
  • Compare service availability across countries
  • Retry an activation with another SMS
