asms MCP server

Phone numbers for AI agents. Connect asms.ai to Claude, ChatGPT, Codex, Cursor, Grok or any MCP client, and your agent can:

get SMS verification codes: a one-time number for a service, charged only when the code arrives and refunded automatically when none does;
rent phone numbers: a number of your own for a day to a year that receives every SMS sent to it, for testing your app's SMS login or an account you'll verify again later;
check the account: balance, prices, stock and open orders.

Everything is paid from your asms wallet, and the tools that spend are marked so your client asks you first.

https://asms.ai/mcp
