Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Mobile Xray MCP

🔬 Take screenshots and analyze your mobile apps with AI assistance - right from your IDE.

License Node.js MCP

Privacy FirstBuilt by Developers for DevelopersWorks Locally

About

I've been building mobile apps for the last 10 years, and one thing that's been consistently challenging without a dedicated UX designer is knowing whether the screens I create are actually user-friendly and intuitive.

Now, this has become dramatically easier. With Mobile Xray MCP, you can ask your favorite AI-powered IDE (Claude, Cursor, Windsurf, VS Code) to take a screenshot of your app and give you instant suggestions on what to improve. No more guessing about UI/UX decisions - get feedback directly in your development workflow.

This tool bridges the gap between development and design by bringing mobile app analysis capabilities directly into your coding environment, making it easier than ever to create polished, user-friendly mobile applications.

Features

  • 🔒 Privacy First: All automation happens locally on your machine - your app screenshots and data never leave your device
  • Fast: Direct communication with local simulators and emulators for instant feedback
  • 📱 Cross-Platform: Supports both iOS simulators and Android emulators
  • 🤖 AI-Powered: Integrates seamlessly with AI coding assistants for intelligent analysis
  • 👨‍💻 Developer-Focused: Built by developers who understand the mobile development workflow

⚡ Quick Start

Prerequisites: Node.js 18+, iOS Simulator or Android Emulator

Add to your IDE config file:

{
  "mcpServers": {
    "mobile-xray": {
      "command": "npx",
      "args": ["-y", "@cultivx/mobile-xray-mcp"]
    }
  }
}

Test: Restart IDE → Start simulator → Ask: "Take a screenshot of my iOS simulator"

Setup Details

Prerequisites

System Requirements:

  • Node.js 18+ (check with node --version)
  • macOS 10.15+ (for iOS development)
  • macOS/Windows/Linux (for Android development)

For iOS Development:

  • Xcode Command Line Tools: xcode-select --install
  • Xcode with iOS Simulator support
  • At least one iOS Simulator installed

For Android Development:

  • Android Studio (includes adb and emulator commands)
  • Android SDK tools in your PATH
  • At least one Android Virtual Device (AVD) created

Verify Your Setup:

# Test Node.js version
node --version  # Should show v18.0.0 or higher

# Test iOS tools (macOS only)
xcrun simctl list devices | head -5

# Test Android tools
adb version

Setup Instructions

For Cursor: See Cursor MCP Documentation

For Claude Desktop: See Claude MCP Quickstart

For Windsurf: See Windsurf MCP Documentation

For VS Code: See VS Code MCP Documentation

Note: This MCP server works with any AI coding assistant that supports the Model Context Protocol.

Basic Usage

  1. Start your mobile simulator/emulator
  2. Open your AI chat in your IDE
  3. Ask for a screenshot: "Can you take a screenshot of my iOS simulator?"
  4. Get AI analysis: "What can I improve about this screen's UX?"

Example Prompts

Platform & Setup

Check which platforms are currently supported by the mobile-xray-mcp on my machine

Accessibility

Take a screenshot of my iOS simulator and tell me what accessibility features I should add
Screenshot my current screen and check if the color contrast meets accessibility standards

UI/UX Feedback

Take a screenshot of the current iOS simulator, and find the code that is related to it, then propose some improvements without making any changes
Take a screenshot of my app and suggest improvements for mobile-first design principles
Analyze the current screen layout and suggest improvements for better user flow

Change and Verify

Make changes and verify your changes work well by taking a screenshot

Troubleshooting & FAQ

Issues:

  • "No simulators found": Start your simulator with open -a Simulator (iOS) or check adb devices (Android)
  • MCP not connecting: Restart your IDE after adding config, verify JSON syntax is correct
  • "Command not found": Install Xcode Command Line Tools (xcode-select --install) or ensure Android SDK is in PATH

Common Questions:

  • Frameworks: Works with React Native, Flutter, Xamarin, or any app in simulator/emulator
  • Physical devices: Not yet supported, simulators/emulators only
  • Privacy: The MCP server operates locally and doesn't collect or send any data. Screenshot images are sent to your AI service by your IDE for analysis
  • Offline: Screenshots work offline, AI analysis needs internet connection

Current Features

Platform Detection: Automatically checks which mobile platforms are available on your system

Privacy First: All processing performed by the MCP server happens locally - no data sent to external servers. However, screenshot images will be sent to your AI service (Claude, ChatGPT, etc.) for analysis, as handled by your IDE's AI agent

Screenshot Capture: Take instant screenshots of iOS simulators and Android emulators

Cross-Platform Support: Works with both iOS and Android development environments

IDE Integration: Seamlessly works with popular AI-powered IDEs and coding assistants
