Zeptap is a Mac app that enables AI agents such as Claude Code, Codex, and Cursor to see, tap, swipe, and type on a real physical iPhone. The Mac reads the iPhone screen over USB and sends touch and keyboard input over Bluetooth via AssistiveTouch, with every action returning a screenshot so the agent can verify its work. It runs a local MCP server on loopback only, requiring no cloud connection, no Xcode, no Developer Mode, and nothing installed on the phone. Users can interact through Zeptap's built-in chat using their existing Claude or ChatGPT subscription, or connect any MCP-compatible agent directly.
