Overview

What is MCP for IOT?

MCP for IOT is a Go implementation of the Model Context Protocol (MCP) server that lets AI models like Claude directly interact with Arduino boards over a serial connection. It acts as a bridge between Claude and your Arduino hardware, enabling AI-controlled hardware automation.

How to use MCP for IOT?

First, build the binary from source with git clone, cd mcp-iot-go, and go install. Upload the provided Arduino firmware (arduino/firmware.ino) to your board. Then configure the MCP client (e.g., Claude Desktop) by adding a server entry to claude_desktop_config.json with the binary’s path. After restarting the client, you can issue natural‑language commands like "Turn on the red LED on pin 6."

Key features of MCP for IOT

List all available serial ports
Read a single line of serial data from a port
Write digital values (HIGH/LOW) to a specified pin
Control a buzzer with on/off and optional duration
Seamless integration with Claude AI

Use cases of MCP for IOT

Turn an LED on or off through a natural‑language request to Claude.
Read sensor data from an Arduino and ask Claude to interpret it.
Activate a relay or buzzer for a set duration via voice or text commands.
Automate hardware responses based on AI analysis of serial readings.

Frequently asked questions

What does MCP for IOT do that alternatives do not?

It provides a direct Model Context Protocol bridge for Arduino hardware, allowing AI assistants like Claude to control digital pins and buzzers using simple serial commands without custom middleware.

What are the runtime dependencies?

You need Go 1.24 or later (to build the binary), an Arduino board with the included firmware uploaded, and a compatible MCP client such as the Claude Desktop App.

Where does data live?

Data is exchanged over the serial port between the Arduino and the MCP server; no cloud storage or external database is used.

What transport and authentication does the server use?

It communicates over USB serial (no authentication). The server does not expose a network endpoint—it runs locally as a subprocess of your MCP client.

Are there any known limits?

The server currently only supports Arduino boards running the provided firmware. It handles digital pin control, buzzer control, and simple serial reads/writes.
