How to Set Up and Use Bridge4Simulator
Bridge4Simulator is a native macOS binary MCP server that gives AI assistants full programmatic control over the iOS Simulator. It exposes 21 tools covering device management, touch input, text entry, screenshot capture, screen recording, app lifecycle control, deep linking, and full UI introspection via accessibility trees and OCR. Mobile developers and QA engineers use it to automate end-to-end testing, demonstrate app flows through natural language, and build autonomous AI agents that can interact with iOS apps exactly as a human tester would.
Prerequisites
- macOS with Xcode and the iOS Simulator installed (Xcode Command Line Tools are sufficient for simulator control)
- Apple Silicon or Intel Mac (separate binaries available for both architectures)
- An MCP-compatible client: Claude Desktop, Claude Code, or Cursor
- Bridge4Simulator binary installed via Homebrew or the curl installer
Install Bridge4Simulator
Install via Homebrew (recommended) or the one-line curl installer. Both methods install the binary to /usr/local/bin/bridge4simulator.
# Homebrew (recommended)
brew tap AppGram/tap
brew install bridge4simulator
# Or via curl
curl -fsSL https://github.com/AppGram/bridge4simulator/releases/latest/download/install.sh | bashVerify the installation
Confirm the binary is installed and check its version.
bridge4simulator --versionBoot an iOS Simulator
Open Xcode → Simulator, or boot a simulator from the command line before connecting via MCP. Bridge4Simulator can also boot simulators via the device_boot tool once connected.
xcrun simctl boot "iPhone 16"Configure Claude Desktop
Add the bridge4simulator MCP server to your Claude Desktop configuration file. The --enable-tools=screenshot flag enables screen capture tools.
Configure Claude Code or Cursor
For Claude Code, add the server to ~/.claude/settings.json. For Cursor, add the HTTP URL to Settings > MCP after starting the server in HTTP mode with 'bridge4simulator mcp --http'.

Example prompts for controlling the iOS Simulator through Claude.
- "Take a screenshot of the iOS Simulator and describe what's on screen"
- "Launch the Settings app and navigate to Wi-Fi settings"
- "Tap the Sign In button and type '[email protected]' in the email field"
- "Scroll down to find the Logout option and tap it"
- "Describe the complete UI hierarchy of the current screen"Troubleshooting Bridge4Simulator
bridge4simulator reports 'no booted simulator found'
Boot a simulator first via Xcode → Simulator or by running 'xcrun simctl boot "iPhone 16"'. You can also use the device_boot MCP tool once a simulator is listed by device_list.
Screenshot tool is not available in the MCP client
Screenshot capture must be explicitly enabled. Add '--enable-tools=screenshot' to the args array in your MCP client config and restart the client.
Installation fails on Apple Silicon Mac
Download the Apple Silicon binary directly from the GitHub releases page (look for an arm64 asset) and install it manually to /usr/local/bin, or use the Homebrew method which selects the correct architecture automatically.
