Passportsim Overview

The passportsim MCP server lets AI agents operate an emulated FoloToy AI Passport through an ESP32-C3 emulator. It can boot firmware builds, interact with device buttons, wait for serial output, inspect the UI tree, and capture screenshots. Use it to develop or debug unmodified ESP-IDF images when physical hardware is unavailable. The emulator runs in the browser through WebAssembly or as a desktop application on macOS and Windows.

Primary Use Cases for Passportsim:
  • Boot ESP-IDF firmware without physical hardware
  • Debug serial output and UI behavior with an AI agent
  • Press simulated device buttons in automated tests
  • Inspect the UI tree after firmware interactions
