How do I use scrcpy-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@scrcpy-mcp take a screenshot" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

scrcpy-mcp

MCP server for Android device control via ADB and scrcpy. Gives AI agents vision and control over Android devices.

Blotcat acting as a puppeteer, controlling an Android phone with strings

Requirements

Node.js >= 22
ADB on PATH (or set ADB_PATH)
scrcpy-server.jar (v3.x or v4.x) — ships with scrcpy
ffmpeg — for H.264 decode and screenshots (optional, ffmpeg-static npm dep available)
ffplay — for live video viewer (optional)

Install

npm install
npm run build

Run

node dist/server.js

Or with npx:

npx @modelcontextprotocol/inspector node dist/server.js

MCP Configuration

Add to your MCP client config:

{
  "mcpServers": {
    "scrcpy": {
      "command": "node",
      "args": ["/path/to/scrcpy-mcp/dist/server.js"],
      "env": {
        "SCRCPY_SERVER_PATH": "/usr/local/lib/scrcpy-v4.0/scrcpy-server"
      }
    }
  }
}

Tools

Session

Tool	Action
`start_session`	Start scrcpy session for fast input/screenshots (10-50x faster). Pushes server, sets up ADB forward tunnel, connects video+control sockets. Idempotent.
`stop_session`	Stop session, fall back to ADB commands
`version`	Report scrcpy version and resolution source (env/binary/default)

Device

Tool	Action
`device_list`	List connected devices with state and model
`device_info`	Model, Android version, SDK, screen size, battery
`screen_on`	Wake screen (scrcpy power message or KEYCODE_WAKEUP)
`screen_off`	Turn screen off
`connect_wifi`	Enable Wi-Fi ADB and connect wirelessly
`disconnect_wifi`	Disconnect wireless ADB
`rotate_device`	Rotate screen (needs active session)
`expand_notifications`	Expand notification panel
`expand_settings`	Expand quick settings
`collapse_panels`	Collapse all panels

Vision

Tool	Action
`screenshot`	Capture screen. Returns scrcpy frame (JPEG) when session active, `adb screencap` (PNG) otherwise.
`screen_record_start`	Start `screenrecord` on device
`screen_record_stop`	Stop and optionally pull recording to host

Input

Blotcat moving at lightning speed leaving afterimages while tapping an Android phone

Coordinate tools accept native display coordinates matching ui_dump bounds.

Tool	Action
`tap`	Tap at (x, y). scrcpy fast path -> ADB fallback.
`swipe`	Swipe from (x1,y1) to (x2,y2) with duration
`long_press`	Long press at (x, y) with duration
`drag_drop`	Drag from (x1,y1) to (x2,y2). Uses `input draganddrop` (API 26+) or swipe fallback.
`input_text`	Type text. Reports screen state, current app, session status. Auto-wakes screen if off. Auto-focuses input field. When `submit=true`, finds send button (by content-desc or resource-id) and taps it.
`key_event`	Send key event by name (HOME, BACK, ENTER, etc.) or keycode
`scroll`	Scroll at position with dx/dy delta

App Management

Tool	Action
`app_start`	Launch app by package name. Prefix with `+` to force-stop first (e.g. `+com.example.app`). Uses scrcpy START_APP when session active, ADB `monkey` otherwise.
`app_stop`	Force-stop app
`app_install`	Install APK from host path
`app_uninstall`	Uninstall by package name
`app_list`	List installed packages with optional `filter` and `system`/third-party scoping
`app_current`	Get foreground app package and activity

Clipboard

Tool	Action
`clipboard_get`	Read clipboard. scrcpy GET_CLIPBOARD (Android 10+) -> ADB with multiple parsing strategies.
`clipboard_set`	Set clipboard text. Optional `paste` flag with scrcpy session.

UI

Blotcat using a magnifying glass to inspect an Android phone broken down into wireframe building blocks

All UI tools use uiautomator dump --compressed under the hood.

Tool	Action
`ui_dump`	Raw UI hierarchy XML
`ui_find_element`	Find elements by text, resource-id, class, or content-desc. `text` matching falls back to `content-desc` if no text match found. Returns coordinates for each match.
`ui_tap_element`	Find element and tap it
`ui_get_state`	Token-efficient Markdown-like tree showing clickable elements and text
`ui_wait_for_element`	Poll UI until element appears or timeout (default 15s)
`ui_smart_fill`	Find element -> tap -> type text -> optional ENTER in one call

Shell

Tool	Action
`shell_exec`	Run arbitrary ADB shell command

File

Tool	Action
`file_push`	Copy file from host to device
`file_pull`	Copy file from device to host
`file_list`	List directory with permissions, owner, size, date

Video Streaming

Tool	Action
`start_video_stream`	Start HTTP MJPEG stream at `http://127.0.0.1:<port>` and open ffplay viewer. Auto-starts session if needed. Default port 7183.
`stop_video_stream`	Stop stream and close viewer

Environment Variables

Variable	Default	Purpose
`ADB_PATH`	`adb`	ADB executable path
`ANDROID_SERIAL`	—	Default device serial
`SCRCPY_SERVER_VERSION`	`3.3.4`	Override scrcpy server version
`SCRCPY_SERVER_PATH`	auto-detect	Path to scrcpy-server.jar
`FFMPEG_PATH`	ffmpeg-static or system `ffmpeg`	ffmpeg binary
`FFPLAY_PATH`	`ffplay`	ffplay binary

    video.ts         — MJPEG stream control

Scrcpy sessions

Two sockets per session: video (raw H.264 from device encoder) and control (binary control messages). ffmpeg decodes H.264 to MJPEG frames in memory for screenshots and the HTTP stream. When video is unavailable (no encoder), control tools and ADB fallback still work.

Coordinate spaces

Callers use native display coordinates (matches wm size and ui_dump bounds). The input system scales these into the downscaled encoder frame size before sending over scrcpy. Without a session, coordinates pass directly to adb shell input tap.

Device Requirements

USB debugging enabled
ADB authorized (one-time screen tap)
Screen can be dead/broken after authorization
Wireless: connect_wifi enables TCP mode and connects
