# Tin Can Smartphone — full public digest

## Product
Tin Can Smartphone turns an Android phone into an SMS gateway. Messages ride the SIM plan you already pay for. Your project or AI agent talks to our cloud via REST API and MCP; the companion app sends and receives SMS on the device.
Website: https://www.tincansmartphone.com/en/

## How it works
1. Your project or AI agent: Call the REST API or MCP server with a personal access token when you need phone tools.
2. Tin Can Cloud: We queue outbound SMS, expose inbound messages, webhooks, and account controls.
3. Your Android device: The Tin Can Smartphone app uses your SIM to send and receive real SMS.
4. Your audience: Texts arrive from a local number people recognize and can reply to.

## MCP setup
Endpoint: https://www.tincansmartphone.com/mcp/
Public (no auth):
```json
{
  "mcpServers": {
    "tincan": {
      "url": "https://www.tincansmartphone.com/mcp/"
    }
  }
}
```
Authenticated (phone tools):
```json
{
  "mcpServers": {
    "tincan": {
      "url": "https://www.tincansmartphone.com/mcp/",
      "headers": {
        "Authorization": "Bearer YOUR_ACCESS_TOKEN"
      }
    }
  }
}
```
Add Authorization: Bearer YOUR_ACCESS_TOKEN (Token YOUR_ACCESS_TOKEN also works) to unlock phone tools (send_sms, read_otp, list_sims, get_status, webhooks, …) subject to your MCP settings and plan. Create a token when signed in; configure tools under the MCP setup console.
