# Aster - Android Device Control

Control your Android device from your AI assistant using MCP (Model Context Protocol). Fully open source and privacy-first — your data never leaves your network.

## Setup

1. **Install and start the server**:
```bash
npm install -g aster-mcp
aster start
```

2. **Install the Aster Android app** on your device from [Releases](https://github.com/satyajiit/aster-mcp/releases) and connect to the server address shown in terminal.

3. **Configure MCP** in your `.mcp.json`:
```json
{
  "mcpServers": {
    "aster": {
      "type": "http",
      "url": "http://localhost:5988/mcp"
    }
  }
}
```

## Security & Privacy

Aster is built with a **security-first, privacy-first** architecture:

- **Self-Hosted** — Runs entirely on your local machine. No cloud servers, no third-party relays. Your data stays on your network.
- **Zero Telemetry** — No analytics, no tracking, no usage data collection. What you do stays with you.
- **Device Approval** — Every new device must be manually approved from the dashboard before it can connect or execute commands.
- **Tailscale Integration** — Optional encrypted mesh VPN via Tailscale with WireGuard. Enables secure remote access with automatic TLS (WSS) — no port forwarding required.
- **No Root Required** — Uses the official Android Accessibility Service API (same system powering screen readers). No rooting, no ADB hacks, no exploits. Every action is permission-gated and sandboxed.
- **Foreground Transparency** — Always-visible notification on your Android device when the service is running. No silent background access.
- **Local Storage Only** — All data (device info, logs) stored in a local SQLite database. Nothing is sent externally.
- **100% Open Source** — MIT licensed, fully auditable codebase. Inspect every line of code on [GitHub](https://github.com/satyajiit/aster-mcp).
