# SimLink

> SMS for AI agents. Turn an old Android phone + a prepaid SIM into a
> dedicated phone number your AI agent can send and receive texts from.

SimLink is a hosted MCP (Model Context Protocol) server. It relays SMS
through a real phone/SIM the user controls. Message content is encrypted at
rest, never logged, and pruned within minutes — no browsable history.

## Connect
- MCP endpoint: https://simlink.snaz.cz/mcp  (Streamable HTTP, `Authorization: Bearer <token>`)
- URL-with-token form: https://simlink.snaz.cz/mcp/<token>  (for clients that only take a URL)
- Get a token: https://simlink.snaz.cz/get  (install the app, sign in, share a SIM)

## Tools
- send_sms(to, body) — send a text from the user's shared SIM
- list_messages(since?, limit?) — recently sent messages (+ send status/error)
- fetch_sms(box?, since?, address?, limit?, request_id?) — read SMS already on the
  phone (inbox/sent). Two-step: start a read, then call again with the returned
  request_id to get the rows. Non-blocking.
