MobAI MCP Server

MCP (Model Context Protocol) server for MobAI - AI-powered mobile device automation. This server enables AI coding assistants like Cursor, Windsurf, Cline, and other MCP-compatible tools to control Android and iOS devices, emulators, and simulators.

Features

• Device Control: List, connect, and manage Android/iOS devices
• UI Automation: Tap, type, swipe, and interact with native apps
• Web Automation: Control Safari/Chrome and WebViews with CSS selectors
• DSL Batch Execution: Execute multiple automation steps efficiently
• AI Agent: Run autonomous agents to complete complex tasks
• Screenshot Capture: Capture and save device screenshots

Prerequisites

• Node.js 18+
• MobAI desktop app running locally (provides the HTTP API on port 8686)
• Connected Android or iOS device (or emulator/simulator)

Example Usage

List devices and take screenshot

Use the list_devices tool to see connected devices.
Then use get_screenshot with the device ID.

Automate Settings app

Use execute_dsl with:
{
  "version": "0.2",
  "steps": [
    {"action": "open_app", "bundle_id": "com.apple.Preferences"},
    {"action": "delay", "duration_ms": 1000},
    {"action": "observe", "context": "native", "include": ["ui_tree"]},
    {"action": "tap", "predicate": {"text_contains": "General"}}
  ]
}

Run AI agent

Use run_agent with device_id and task: "Open Settings and enable WiFi"

Comparison with Claude Code Plugin

Feature	Claude Code Plugin	MCP Server
Platform	Claude Code only	Any MCP client
Tools	http_request (generic)	Named tools + http_request
Resources	Skills (markdown)	MCP resources
Setup	Plugin install	npx

The MCP server provides the same functionality as the Claude Code plugin but works with any MCP-compatible AI tool.

Troubleshooting

"Connection refused" error

• Ensure MobAI desktop app is running
• Check that API is available at http://127.0.0.1:8686

"Bridge not running" error

• Use start_bridge tool first before automation
• iOS bridge may take up to 60 seconds to start

Screenshots not visible

• Screenshots are saved to /tmp/mobai/screenshots/
• Use your AI tool's file reading capability to view them
