Bridge4Simulator MCP

Bridge4Simulator MCP is an open-source MCP (Model Context Protocol) server that enables AI assistants to control iOS Simulator directly from your development environment. It seamlessly integrates with Claude Desktop, Cursor, Claude Code, and other MCP-compatible clients, allowing AI to interact with iOS applications through touch gestures, text input, screenshots, and UI element analysis. The tool provides 21 different tools for device management, input handling, screen capture, app control, navigation, and UI inspection.

1. Install via Homebrew: Run brew tap AppGram/tap && brew install bridge4simulator to install the CLI tool.
2. Start the MCP Server: Run bridge4simulator mcp --http in your terminal to start the server.
3. Configure Your AI Client: Add the bridge4simulator configuration to your MCP settings in Claude Desktop, Cursor IDE, or Claude Code CLI.
4. Open iOS Simulator: Ensure Xcode and iOS Simulator are installed and running on your Mac.
5. Interact via AI: Ask your AI assistant to perform tasks like "Take a screenshot of the iOS Simulator" or "Find and tap the settings button."

• Device Management: List, boot, and shutdown iOS simulator devices with simple commands.
• Touch Input & Gestures: Perform tap, swipe, and text input actions programmatically through AI assistants.
• Screen Capture: Take screenshots and record screen sessions for documentation and debugging.
• App Lifecycle Control: Install, launch, and terminate iOS applications directly from the MCP interface.
• UI Accessibility Tree: Analyze UI elements using accessibility tree inspection, OCR, and element search capabilities.
• URL & Deep Link Navigation: Open URLs and deep links directly in the iOS Simulator.
• Macro Automation: Create and play automation sequences for repetitive testing workflows.

#1 Automated iOS App Testing Use AI assistants to automatically navigate through your iOS app, taking screenshots and verifying UI elements without manual intervention.

#2 Mobile Development Debugging Let AI inspect UI accessibility trees, find specific elements, and describe screen contents while you focus on fixing code issues.

#3 Documentation & Demo Creation Capture screenshots and record screen sessions with AI-guided navigation to create comprehensive app documentation and demo videos.

#4 QA Workflow Automation Create macro sequences for repetitive test scenarios and let AI execute them across different simulator devices.

#5 Cross-Device UI Verification Boot multiple simulator devices and use AI to verify UI consistency across different iPhone and iPad screen sizes.
