iPhone-mcp

MCP server that lets AI agents control real iPhones and iPhone simulators on MacOS. Works with Claude Code, Cursor, Codex, OpenCode, and any MCP-compatible AI agent.

Requirements

• macOS
• Xcode (install from App Store or xcode-select --install)
• Node.js 18+
• Homebrew

Installation

npm install @blitzdev/iphone-mcp

Quick Start

Global (use in any project)

npx @blitzdev/iphone-mcp --setup-all

This installs dependencies and configures @blitzdev/iphone-mcp for all your AI agents. It automatically sets up Claude Code, Cursor, Codex, OpenCode.

NOTE: For Cursor, you need to enable the blitz-iphone MCP server in Cursor Settings

Project-scoped (one project only)

cd <your project>
npx @blitzdev/iphone-mcp --setup-here

This prompts you to choose which AI agents to configure (Claude Code, Cursor, Codex, OpenCode) and writes the config files into your project directory. @blitzdev/iphone-mcp will only be available when you open an agent inside that directory.

Then just ask

Open a new AI agent session and ask:

> scan the simulator screen and tell me what you see

> connect to my iPhone and test the login flow

> find bugs in my app — tap around, try edge cases, report anything weird

What can it do?

iPhones

Connect your iPhone via USB or make sure it's on the same Wi-Fi network (home/office networks work, public cafe Wi-Fi won't).

First-time setup — your iPhone needs:

1. Developer Mode enabled (Settings > Privacy & Security > Developer Mode)
2. Trust this computer when prompted on the phone

Then ask your agent:

> connect to my iPhone

The agent will build and install WebDriverAgent on your phone (takes 1-3 minutes the first time), then give you a URL like http://localhost:5152?udid=... — open it in your browser to see a live view of your phone screen.

Simulators

Boot any iPhone simulator, then ask your AI agent to interact with it. No extra setup needed beyond --setup-all or --setup-here.

> what apps are installed on the simulator?
> launch Safari and go to example.com
> take a screenshot

Example session

You:    test the checkout flow in my app
Agent:  Let me scan the simulator to see what's on screen.

        [calls scan_ui]

        I can see the home screen. Let me launch your app first.

        [calls launch_app with bundleId "com.myapp"]
        [calls get_screenshot]

        The app is open on the main screen. I see a "Shop" tab at the bottom.
        Let me tap it and walk through the checkout flow.

        [calls device_action: tap on "Shop" tab]
        [calls scan_ui]

        I see a list of products. Let me add one to cart...

MCP Tools reference

These are the tools your AI agent can call:

Manual MCP configuration

If you'd rather configure things yourself:

Claude Code — add to ~/.claude.json (global) or .mcp.json (project):

{
  "mcpServers": {
    "blitz-iphone": {
      "command": "npx",
      "args": ["@blitzdev/iphone-mcp"]
    }
  }
}

Cursor — add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project):

{
  "mcpServers": {
    "blitz-iphone": {
      "command": "npx",
      "args": ["@blitzdev/iphone-mcp"]
    }
  }
}

Codex — add to ~/.codex/config.toml (global) or .codex/config.toml (project):

[mcp_servers.blitz-iphone]
command = "npx"
args = ["@blitzdev/iphone-mcp"]

OpenCode — add to opencode.json in your project root:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "blitz-iphone": {
      "type": "local",
      "command": ["npx", "-y", "@blitzdev/iphone-mcp"],
      "enabled": true
    }
  }
}

Troubleshooting

"No booted simulator found" — Open Simulator.app or run xcrun simctl boot "iPhone 16" first.

Physical device not detected — Make sure Developer Mode is on, the phone is connected via USB, and you've tapped "Trust" on the phone.

WDA build fails — Open Xcode > Settings > Accounts and make sure an Apple ID is signed in. Xcode needs a signing identity to build WDA.

"Connection refused" errors — The idb companion may have crashed. Run npx @blitzdev/iphone-mcp --setup-all again to re-initialize.
