sms-florin-mcp

MCP server for sms-florin — lets AI coding agents (Claude Code, Claude Desktop, Cursor, Codex, Windsurf, Cline...) rent a real UK phone number and receive an SMS/OTP verification code directly inside an agentic workflow. Useful when an agent is testing a signup/verification flow and needs a real code instead of a mocked one.

Numbers are real SIM cards on UK carrier networks (EE/Three) — not VoIP — via sms-florin's own GOIP hardware.

Setup

Get an API key at flo-voice1.com/api-access (balance is shared with your regular account).

Claude Code / Claude Desktop

claude mcp add sms-florin -e SMS_FLORIN_API_KEY=your_key_here -- npx -y sms-florin-mcp

Or in claude_desktop_config.json:

{
  "mcpServers": {
    "sms-florin": {
      "command": "npx",
      "args": ["-y", "sms-florin-mcp"],
      "env": { "SMS_FLORIN_API_KEY": "your_key_here" }
    }
  }
}

Cursor / Windsurf / other MCP clients

Same shape — point the client's MCP config at npx -y sms-florin-mcp with SMS_FLORIN_API_KEY set in the env.

Tools

Example flow

Rent a WhatsApp number and wait for the verification code.

The agent calls rent_number({ serviceSlug: "whatsapp" }), then wait_for_sms({ rentalId }), and gets the code back to type into the signup form it's testing.

Need one for your own API?

I build custom MCP servers like this one — npm package, published to the official Anthropic MCP registry / Docker MCP catalog / Glama, same setup as above. Details on Fiverr, starting at $90.
