sms · mcp · your sim
A small, self-hostable server that gives an AI agent a real phone number. It relays texts through an old Android phone and a prepaid SIM you control — send and receive over the Model Context Protocol. I built it for my own agents and put it here in case it's useful to you. It's open source.

Nothing in the middle stores your texts. The server holds a message only long enough to hand it from the agent to the phone (or back) — encrypted, never logged, pruned within minutes.
mcp tools
send_sms(to, body)
Send a text from the SIM the user shared with you.
list_messages(since?, limit?)
Recently sent messages, with delivery status and any error.
fetch_sms(box?, since?, address?, limit?, request_id?)
Read SMS already on the phone (inbox/sent). Two-step and non-blocking: start a read, then call again with the returned request_id to collect the rows.
Args marked ? are optional. Full machine-readable summary at /llms.txt.
