Documentation Overview

CODASMS MCP Server

Receive one-time SMS/OTP verification codes from your AI agent. An MCP server over the CODASMS Reseller API — get a number, wait for the code, release it — across 700+ services and 180+ countries, pay only on delivery.

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

Tool	What it does
`get_balance`	Your current spendable balance.
`list_services`	Buyable services with live price + stock (filter by `service` / `country`).
`list_countries`	Countries with buyable numbers (optional `service` filter).
`get_number`	Buy a number for a service+country. Charges your balance (auto-refunds if no code in 20 min).
`wait_for_otp`	Poll an order until the code arrives (or timeout / refund).
`check_order`	One-shot status check for an order.
`release`	Cancel an order and refund now (unless the code already arrived).

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)

server.ts

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

Claude Desktop

Add to claude_desktop_config.json:

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):

Terminal

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

Code

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

Env var	Purpose	Default
`CODASMS_API_KEY`	Your `coda_live_` reseller key (stdio mode).	— (required)
`CODASMS_API_BASE`	API base URL.	`https://api.codasms.com`
`CODASMS_MAX_PRICE_CENTS`	Global cap for `get_number`, in US cents.	unset
`PORT`	HTTP mode port.	`8080`

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.
