agent-device MCP server

This is a helper for people who build or test apps. It lets your AI assistant actually open an app on a phone simulator or a real device, look at the screen, tap buttons, and take screenshots. If you work on iOS or Android apps, this saves you from describing every screen by hand.

What this MCP server does

You ask your AI to do something with an app, like open it or tap a button. The AI uses this helper, which talks to the app running on a simulator, emulator, or real device. The helper reads the screen and reports back what it sees, then performs the taps or typing you asked for. You get back a short report of what happened, plus screenshots or logs if you want them. You can also save a run so you can repeat it later.

What you can do with it

• Open an app on an iOS simulator or Android emulator
• Tap buttons, fill in fields, and scroll through screens
• Take screenshots and record video as proof of what happened
• Read the app's screen so your AI knows what is there
• Capture logs and crash details when something goes wrong
• Save a working run as a script you can replay later
• Check performance and see if the app is doing extra work

Try asking your AI

• “Open the Contacts app on the iOS simulator and add a new contact named Ada”
• “Run the checkout flow on Android and take a screenshot at each step”
• “Reproduce this crash and show me the logs right before it happens”
• “Check if my latest change causes the screen to re-render too often”

What it gives back to you

You get short, readable answers in the chat, like what the app is showing and what changed after each action. It can also hand back screenshots, video files, logs, and performance numbers. If you asked it to save a run, you get a script file you can use again. Everything shows up as normal chat messages and files you can open.
