About Iot Go

Iot Go is an MCP server published by sukeesh in the Developer Tools category: mCP Server for Sensors.

The repository has 8 stars and 2 forks, with the last commit a year ago. Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.

Install

From source
git clone https://github.com/sukeesh/mcp-iot-go

This server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

Tools (4)

buzzer_controlControls a buzzer connected to an Arduino pin with optional duration

Parameters not published.

port_listLists all available serial ports

Parameters not published.

read_serial_lineReads a single line of data from a specified serial port

Parameters not published.

write_digitalWrites a digital value (HIGH/LOW) to a pin on a specified port

Parameters not published.

README

MCP for IOT

Go

Overview

MCP for IOT is a Go implementation of the Model Context Protocol (MCP) server that allows AI models like Claude to directly interact with IoT devices, specifically Arduino boards. This server acts as a bridge between Claude and your Arduino hardware, enabling AI-controlled hardware automation.

Features

  • 🔌 List available serial ports
  • 📡 Read data from Arduino's serial port
  • 🚦 Control digital pins (LEDs, relays, etc.)
  • 🔊 Control buzzers with on/off and duration settings
  • 🤖 Seamless integration with Claude AI

Usage

https://github.com/user-attachments/assets/46d7d731-f5d0-4acd-b53e-c00be8b83215

Prerequisites

  • Go (version 1.24 or later)
  • Arduino hardware with USB connection
  • Claude Desktop App or compatible MCP client

Installation

Build from Source

git clone https://github.com/sukeesh/mcp-iot-go.git
cd mcp-iot-go
go install

The binary will be installed to your GOBIN directory, which should be in your PATH.

Arduino Setup

  1. Connect your Arduino to your computer
  2. Upload the provided Arduino firmware: 
    arduino/firmware.ino

This firmware accepts commands via serial communication:

  • M,pin,mode - Sets pin mode (e.g., M,6,OUTPUT)
  • D,pin,value - Controls digital pins (e.g., D,6,HIGH or D,6,LOW)
  • BZ,pin,state - Controls buzzers (e.g., BZ,8,ON or BZ,8,OFF)

Configuration with MCP Client

Configure Claude Desktop:

  1. Open Claude Desktop → Settings → Developer → Edit Config
  2. Add the following to your claude_desktop_config.json:
{
  "mcpServers": {
    "iot": {
      "command": "<path-to-mcp-iot-go-binary>",
      "env": {}
    }
  }
}
  1. Restart Claude Desktop

Available Tools

Tool Description
port_list Lists all available serial ports
read_serial_line Reads a single line of data from a specified serial port
write_digital Writes a digital value (HIGH/LOW) to a pin on a specified port
buzzer_control Controls a buzzer connected to an Arduino pin with optional duration

Usage Examples

After setup, you can interact with your Arduino hardware directly through Claude:

  • "List all available serial ports"
  • "Read data from the Arduino on port /dev/cu.usbmodem12401"
  • "Turn on the red LED on pin 6"
  • "Activate the buzzer on pin 8 for 2 seconds"

Development

Project Structure

  • main.go - MCP server setup and tool definitions
  • internal/tools.go - Tool implementation for Arduino communication
  • arduino/firmware.ino - Arduino firmware for processing commands

Questions

About Iot Go

How do I install Iot Go?

No package has been published for this server, so install it from source: clone the repository and follow its README.

Is Iot Go safe to use with an AI agent?

Its trust score is 41 out of 100 (fair). It passes 3 of the 6 static security checks run so far; the failures are listed above. It has no ConduID identity yet, so agent calls to it are not receipted.

Is Iot Go still maintained?

The last commit was a year ago. That's long enough that you should check whether the maintainer is responding to issues before depending on it.
