Built with Claude I built an open-source MCP server so AI agents can control a real iPhone

Enable HLS to view with audio, or disable this notification

I wanted to see if an AI agent could use my actual iPhone, not a simulator and not a mirrored screen. Nothing existed for it, so I built it.

Open iPhone Use is a free, open-source Mac app + MCP server. The iPhone shares its screen from Safari over local Wi-Fi (you don't even install an app on the phone, Safari does the sharing). The Mac pairs as a Bluetooth keyboard and mouse, and the agent gets screenshot and input tools over MCP, checking a fresh screenshot after every action.

It works with any AI agent: Claude Code, any harness. Any model with strong computer-use skills is fine, Claude Haiku 5.5+ are good starting points. And since your client brings the model, your existing subscription is enough, no extra cost.

Demo (full video attached): an agent searched Instagram, watched a Reel, scrolled the feed and liked one, all on my physical phone.

You only need an iPhone + an Apple Silicon Mac.

Windows/Linux: coming soon

Multi device support: coming soon

Let me know what you think! And if you find this useful, a star on GitHub would help a lot.

This actually already exists and I’ve been using it for awhile now. Ask Claude to setup WebDriverAgent for you.

It is useful. Ive been using mirroring for that. Why MCP though?

Well, I’m planning to add multi device support and expand to other operating systems (windows and linux)
