Tapp — iOS simulator for your coding agent

Copilot has built-in browser tools — open a page, read its structure, click, screenshot. This extension gives it the same powers on the iOS simulator, backed by tapp (tapp-mcp on npm):

Browser (built-in)	iOS (this extension)
`open_browser_page`	`tapp_open_ios_app` — builds the Xcode project in your repo if needed, opens the app
`read_page`	`tapp_read_ios_screen` — structured accessibility snapshot of the rendered screen
`screenshot_page`	`tapp_ios_screenshot` — visual capture, shown inline
`click_element` / `type_in_page`	`tapp_ios_tap` / `tapp_ios_type`
—	`tapp_run_ios_qa` — autonomous QA: deterministic ship/no-ship verdict + evidence + recording

An embedded simulator panel opens beside your editor and mirrors the phone while the agent works — like the browser preview, but for iOS.

Use it

Open an iOS repo and ask Copilot (agent mode):

"Open this iOS app on the simulator and tell me what's on the home screen." "Tap through to Settings and screenshot it." "Run autonomous QA — is this ship-ready?"

No bundle ids, no configuration. Tapp finds the Xcode project, picks the scheme, builds for the simulator, installs, and drives the app through its accessibility surface.

Requirements

macOS with Xcode (simulator runtimes installed) and Node ≥ 18. The engine is fetched automatically via npx tapp-mcp on first use (~2 min one-time harness build).

Everything runs locally on your Mac; nothing leaves it. MIT-licensed, like the engine.
