screen-buffer-mcp 1.0.0

MCP server for fast Android screenshots via scrcpy frame buffer

device-manager-mcp

MCP server for fast Android device interaction with scrcpy acceleration.

Features

• Fast operations via scrcpy (~50ms latency)
• Automatic fallback to adb (~500ms) when scrcpy unavailable
• Screenshots, taps, swipes, typing - all device interactions
• Works with Claude Code and any MCP-compatible client

Requirements

• macOS 12+, Python 3.11+, adb, scrcpy 3.x
• Android device connected via USB

See docs/requirements.md for detailed setup instructions.

Usage with Claude Code

Add to your .mcp.json:

{
  "mcpServers": {
    "device-manager": {
      "command": "uvx",
      "args": ["device-manager-mcp"]
    }
  }
}

Or add globally:

claude mcp add device-manager -s user -- uvx device-manager-mcp

Available Tools

Tool	Description	Latency
device_screenshot	Capture screen as PNG	~40ms (scrcpy) / ~500ms (adb)
device_tap	Tap at coordinates	~50ms (scrcpy) / ~200ms (adb)
device_swipe	Swipe gesture	~300ms
device_type	Type text	~100ms
device_press_key	Press BACK, HOME, ENTER, etc.	~50ms
device_list	List connected devices	~100ms
device_screen_size	Get screen dimensions	~10ms
device_backend_status	Check active backend	instant

How It Works

The server automatically selects the best backend:

1. scrcpy backend (if available): Uses MYScrcpy library to communicate directly with scrcpy server on device. Provides ~50ms latency for screenshots and input.

2. adb backend (fallback): Uses standard adb commands. Works everywhere but slower (~500ms for screenshots).

Example

# Claude Code will automatically use these tools:

# Take a screenshot
device_screenshot()

# Tap at coordinates
device_tap(x=540, y=1200)

# Swipe down
device_swipe(start_x=540, start_y=800, end_x=540, end_y=1600)

# Type text
device_type(text="Hello World")

# Press back button
device_press_key(key="BACK")

Configuration

Environment Variables
