📋 Requirements

macOS: Required for iOS simulator support
Node.js: v14.0.0 or higher
Homebrew: Required for installing dependencies
XCode: With iOS simulators installed

🚀 Installation

The easiest way to install this server is through Cline:

Simply ask Cline:

Add this mcp to cline https://github.com/InditexTech/mcp-server-simulator-ios-idb

Cline will handle the installation process automatically, including dependency management and configuration.

Alternatively, you can install it manually:

# Clone the repository
git clone https://github.com/InditexTech/mcp-server-simulator-ios-idb.git
cd mcp-server-simulator-ios-idb

# Create and activate Python virtual environment
python3 -m venv venv
source venv/bin/activate  # On Unix/macOS

# Install dependencies
npm install

# Build the project
npm run build

# Start the project
npm start

# Run tests
npm test

The installation process will automatically:

Check if you're running macOS
Install idb-companion via Homebrew
Install fb-idb via pip in the virtual environment

Note: Make sure to keep the virtual environment activated while using the server. If you close your terminal and come back later, you'll need to reactivate the virtual environment with the source venv/bin/activate command before running npm start.

🔌 MCP Integration

To use this server with Claude or other LLM assistants:

Add the server to your MCP settings in Claude Desktop:

{
  "mcpServers": {
    "ios-simulator": {
      "command": "node",
      "args": ["/path/to/mcp-server-simulator-ios-idb/dist/index.js"],
      "env": {}
    }
  }
}

The LLM can now use natural language commands to control iOS simulators:

create a simulator session with iPhone 14
install app /path/to/my-app.ipa
launch app com.example.myapp
tap at 100, 200
take a screenshot

📚 Usage as a Library

You can also use this package as a library in your own projects:

🔰 Basic Usage

import { createMCPServer } from 'mcp-server-simulator-ios-idb';

async function main() {
  // Create an instance of the MCP server
  const { orchestrator } = createMCPServer();
  
  // Process natural language commands
  
  // Create a simulator session
  const sessionResult = await orchestrator.processInstruction('create session');
  console.log(`Session created: ${sessionResult.data}`);
  
  // Interact with the simulator
  await orchestrator.processInstruction('tap at 100, 200');
  
  // Capture a screenshot
  const screenshotResult = await orchestrator.processInstruction('take screenshot');
  console.log(`Screenshot saved at: ${screenshotResult.data}`);
}

main().catch(console.error);

🚀 Advanced Usage

You can also use the individual components directly:

import { 
  IDBManager, 
  NLParser, 
  MCPOrchestrator,
  ParserToOrchestrator,
  OrchestratorToIDB
} from 'mcp-server-simulator-ios-idb';

// Create instances
const idbManager = new IDBManager();
const parser = new NLParser();
const orchestrator = new MCPOrchestrator(parser, idbManager);

// Use the components directly
const sessionId = await idbManager.createSimulatorSession({
  deviceName: 'iPhone 12',
  platformVersion: '15.0'
});

await idbManager.tap(sessionId, 100, 200);

🔍 Architecture

The server consists of three main components:

IDBManager: Low-level component that interacts directly with iOS simulators through idb.
NLParser: Component that interprets natural language instructions and converts them into structured commands.
MCPOrchestrator: Central component that coordinates interactions between the parser and the IDBManager.

These components are connected through adapters:

ParserToOrchestrator: Converts parser results into orchestrator commands.
OrchestratorToIDB: Translates orchestrator commands into IDBManager calls.

🔌 MCP Integration

To use this server with the Model Context Protocol:

Add the server to your MCP settings:

{
  "mcpServers": {
    "ios-simulator": {
      "command": "node",
      "args": ["/path/to/mcp-server-simulator-ios-idb/dist/index.js"],
      "env": {}
    }
  }
}

Connect to the server in your LLM application:

const result = await useMcpTool({
  serverName: "ios-simulator",
  toolName: "process-instruction",
  arguments: {
    instruction: "create simulator session"
  }
});
