Unified Interface FAQs

Question 1

What is Unified Interface (MCP/U) and its main purpose?

Accepted Answer

Unified Interface (MCP/U) enables AI agents, such as LLMs, to dynamically discover and control Arduino-compatible microcontrollers. Its core purpose is to transform any physical device connected to an MCU into an AI-controllable tool.

Question 2

How does Unified Interface connect AI agents to physical devices?

Accepted Answer

It uses an npm client (`mcpu-client`) that communicates with microcontroller firmware (via the `McpIot` library) over Serial or TCP. The client dynamically registers the MCU's capabilities and pin configurations with the AI agent, allowing the AI to call these functions by name.

Question 3

What types of microcontrollers are compatible with Unified Interface?

Accepted Answer

Unified Interface is compatible with any Arduino-compatible microcontroller. The provided `McpIot` library is designed for easy integration with Arduino IDE or PlatformIO projects, making it versatile for various MCU boards.

Question 4

Can Unified Interface control multiple devices simultaneously?

Accepted Answer

Yes, Unified Interface supports multi-device control. You can configure multiple microcontrollers using the `DEVICES` environment variable, allowing a single AI agent instance to manage several physical devices concurrently with uniquely named tools.

Question 5

What operations can I perform on microcontrollers using Unified Interface?

Accepted Answer

AI agents can perform standard operations such as GPIO control (reading digital inputs, writing digital outputs), PWM output for controlling motors or dimming LEDs, ADC reading for sensors, and even custom-defined functions. All these capabilities are dynamically discovered by the AI.
