Quick Install

Brew:

  brew tap AppGram/tap
  brew install bridge4simulator
  bridge4simulator --version

Installer:

curl -fsSL https://github.com/AppGram/bridge4simulator/releases/latest/download/install.sh | bash

Under the hood, MCP relies on a custom-built bridge. For inquiries about commercial use of the tool powering this CLI, be free to contact us

Configuration

First run, in terminal: bridge4simulator mcp --http

Cursor IDE

Go to Settings > MCP and add:

Then add config

    "bridge4simulator": {
       "url": "http://localhost:8080/mcp"
    },

Or in Claude Desktop config:

{
  "mcpServers": {
    "bridge4simulator": {
      "command": "/usr/local/bin/bridge4simulator",
      "args": ["mcp", "--enable-tools=screenshot"]
    }
  }
}

Claude Desktop doesn't support url for local development MCPs.

Claude Code CLI

Add to ~/.claude/settings.json or project .mcp.json:

{
  "mcpServers": {
    "ios-simulator": {
      "command": "/usr/local/bin/bridge4simulator",
      "args": ["mcp", "--enable-tools=screenshot"]
    }
  }
}

Demo

This demo highlights autonomous navigation and the internal reasoning process behind task execution. Under the hood, MCP uses a powerful CLI tool that enables instant OCR and UI extraction while keeping token consumption minimal for rapid problem solving.
