Usemymac — Development skill for Claude Code

UseMyMac


*Left: Claude Code, anywhere. Right: a Mac running `usemymac up`. The agent reaches it only through the printed URL.*

Turn your Mac into a remote computer-use host. One command on the Mac, one paste into Claude Code or Codex, and the agent can see your screen, click, type, and open apps.

Built on [CUA](https://github.com/trycua/cua)'s `computer-server` for the macOS driver. UseMyMac adds the parts that make it safe to reach from outside: a bearer token, a tool allowlist that hides shell and filesystem access by default, a Cloudflare quick tunnel, keep-awake, and a permissions preflight.

Quick start

uvx usemymac up

Or without uv installed:

curl -fsSL https://raw.githubusercontent.com/yunfeng-enrich/usemymac/main/install.sh | sh

Either way UseMyMac fetches cloudflared on first run and starts the server. It prints one line to paste into your agent, plus the one-line commands:

claude mcp add --transport http usemymac https:////mcp
codex mcp add usemymac --url https:////mcp

The token lives in the URL so no client needs custom headers. `Authorization: Bearer ` against `https:///mcp` works too.

Permissions

macOS grants Screen Recording and Accessibility per app, and the app is whichever terminal launched `usemymac`. The first run triggers both prompts. Screen Recording only takes effect after that terminal is fully quit and reopened. Without it, screenshots are black and window titles are empty. Check with:

usemymac check

What is exposed

By default: screenshot, mouse, keyboard, clipboard, windows, app launch, and the accessibility tree. Not exposed unless you ask:

• --allow-shell adds computer_run_command
• --allow-files adds file read, write, and delete tools

Other flags: `--no-tunnel` for LAN or SSH-forwarded use, `--widt
