This server lets an AI agent (Claude Desktop, Cursor, or anything that speaks MCP) buy a phone number and read the verification code programmatically. It's a thin wrapper over the public CODASMS Reseller API — it holds no logic of its own; every charge and refund is decided server-side by the API.

You bring your own key. Getting one is free to sign up: https://codasms.com/reseller.

Tools

get_number accepts an optional max_price_cents (or set CODASMS_MAX_PRICE_CENTS) so an autonomous agent can't buy a number priced above your cap.

Quick start (local / stdio)

export CODASMS_API_KEY=coda_live_xxxxxxxx   # from https://codasms.com/reseller
npx codasms-mcp

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "codasms": {
      "command": "npx",
      "args": ["-y", "codasms-mcp"],
      "env": { "CODASMS_API_KEY": "coda_live_xxxxxxxx" }
    }
  }
}

Then ask: "Get me a Telegram number in the UK and read the code."

Remote (HTTP) mode

The same tools are served over Streamable HTTP, so you can host one instance for many users — each sends their own key as a Bearer token (nothing is stored server-side):

npm run build && npm run start:http     # listens on :8080, POST /mcp

POST /mcp
Authorization: Bearer coda_live_xxxxxxxx
Content-Type: application/json

src/http.ts is a portable Node server (Deno Deploy, Railway, Fly, any container). For Cloudflare Workers, swap the Node http handler for a fetch handler — the server factory in src/server.ts is transport-agnostic and stays unchanged.

Configuration

Notes

• Rate limit: the API allows 60 requests/min per key; wait_for_otp polls no faster than once every 5s by default to stay well under it.
• Money safety: get_number spends real balance the moment it's called. If no code arrives, the order auto-refunds after 20 minutes, or call release to refund immediately.
• Codes: services and countries use the API's codes (e.g. tg, wa, country 6) — use list_services / list_countries to discover them.
