Android Shizuku

An open-source Model Context Protocol (MCP) server for Android, running in Termux. It allows LLM agents to control your Android device securely via Shizuku (rish) and Termux:API.

Features

• Streamable HTTP Transport: Modern MCP transport for robust communication.
• Single Universal Shell Tool: One MCP tool for Termux and rish, designed to feel closer to a real terminal.
• Hybrid Exec + Session Model: The same shell tool supports one-shot commands and persistent shell sessions.
• Raw Inline First: If stdout/stderr fit the budget, they are returned whole instead of being split into preview sections.
• Long-Running Recovery: One-shot commands can still be polled/cancelled when they outlive the sync budget.
• Interactive Session Flow: Sessions support write/read/close on a persistent shell cursor.
• Shizuku Integration: High-privilege Android commands can be routed through rish.
• Low-Context UX: Error payloads stay short and operational for weak LLMs.
• Artifact Management: Command/session output is persisted for follow-up inspection when needed.

Prerequisites

1. Termux: Install from F-Droid.
2. Termux:API: Install both the app (F-Droid) and the package (pkg install termux-api).
3. Shizuku: Set up on your device (Wireless Debugging or Root).
4. rish: Copy rish to your Termux home directory (~/bin/rish) and ensure it's executable and not writable by others (on Android 14+).

Installation

1. Clone this repository in Termux.
2. Run the installation script:

   ./install.sh
   

3. Copy the Bearer token from the .env file created.

Usage

Start the server:

./run-server.sh

By default, the server runs on http://127.0.0.1:8765/mcp.

Connecting an MCP Client

Use the following configuration (e.g., in Claude Desktop):

{
  "mcpServers": {
    "android": {
      "command": "python",
      "args": ["/path/to/android-shizuku-mcp/src/main.py"],
      "env": {
        "MCP_AUTH_TOKEN": "your-token-here"
      }
    }
  }
}

Or connect via HTTP directly using an MCP client supporting Streamable HTTP.

Available Tools

• Shell: shell is the primary universal tool. It supports exec, poll, open_session, write, read, close, and cancel.
• System: doctor
• Artifacts: list_artifacts

Autostart

Run ./setup_boot.sh to create a Termux:Boot script. Ensure the Termux:Boot app is installed.

Security

• Bind to 127.0.0.1 unless you intentionally expose the server another way.
• Bearer token authentication is supported and recommended.
• The shell path is permissive by design and is not a command-policy sandbox.
• The server is optimized for low-friction command execution and low-context responses, not strict shell filtering.
