MCP server giving AI agents programmatic control over Android devices and emulators via ADB. 11 tools covering UI inspection, screen interaction, ADB commands, and change detection.
AI-powered mobile device automation for Android and iOS devices, emulators, and simulators
Returns the current Android screen as an XML UI hierarchy.
Use this when you need to locate element coordinates, read text, or find resource IDs to
interact with. Do not call this after every action — only call it when you actually need to
read screen content. To check if the screen changed after an action, use snapshot_ui before
the action and detect_ui_change after.
tap_screen
A tap gesture at the given pixel coordinates on the Android screen.
swipe_screen
A swipe gesture on the Android screen from (x1,y1) to (x2,y2) over the given duration.
type_text
Text input into the currently focused Android input field.
Spaces are encoded automatically.
press_key
A key event sent to the Android device using the given keycode integer.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Agent Droid Bridge is categorized under Browser Automation and uses a local stdio subprocess. In contrast, Mobai MCP belongs to Browser Automation using local stdio subprocess. Select Agent Droid Bridge when you need capabilities focused on browser automation and Mobai MCP when you require tools for browser automation.

and base64-encoded image data.
list_devices
All Android devices currently visible to ADB, with their serial numbers,
connection state, and model names.
launch_app
An Android app launched by its component name (package/activity).
execute_adb_command
The output of an ADB command. Parsed safely via shlex and never passed to a system shell.
snapshot_ui
Takes a lightweight snapshot of the current UI state and returns a short token.
Use this before performing an action (tap, swipe, launch, key press) when you only need to
confirm the screen changed afterward — not read its content. Pass the returned token to
detect_ui_change as baseline_token. This avoids loading the full XML hierarchy into context
unnecessarily. Do not use this when you need to read or interact with screen elements — use
get_ui_hierarchy for that.
detect_ui_change
Polls the UI hierarchy after an action and returns when the screen content changes or the
timeout is reached. Returns changed status and elapsed time. By default, omits the XML
hierarchy for efficiency — set return_hierarchy=True to receive the full hierarchy.
For efficient change detection: call snapshot_ui before the action, perform the action, then
call detect_ui_change with baseline_token. Only use without baseline_token when you need to
wait for a slow transition (loading screens, animations). Do not use to read the current
screen state — use get_ui_hierarchy for that.
get_screen_elements
Structured list of UI elements currently visible on the Android screen.
Returns elements filtered and shaped by the chosen mode. Prefer 'tappable' for
navigation and 'interactive' when you need XPath or bounds for ADB commands.
Only use 'all' as a last resort — it returns every node and can be large.
