What is Serial MCP Server?

Serial MCP Server is a serial communication server developed based on Rust. It provides AI assistants with the serial communication capabilities with hardware devices through the Model Context Protocol (MCP). It supports cross - platform operations and can connect to embedded devices such as STM32 and Arduino to achieve two - way data communication.

How to use Serial MCP Server?

You need to install the Rust environment first, then clone and compile the project. After configuring the MCP client (such as Claude), you can interact with hardware devices through natural language instructions.

Applicable scenarios

Suitable for scenarios that require interaction with hardware, such as embedded development debugging, IoT device control, hardware prototype testing, and industrial automation device communication.

Main features

Cross - platform support
Supports Windows (COMx), Linux (/dev/ttyXXX), and macOS (/dev/tty.xxx) systems, and automatically detects serial port devices.
Hardware integration
Verified to support multiple embedded devices such as STM32, Arduino, and ESP32, and is compatible with common USB - to - serial chips such as CH340 and FTDI.
AI integration
Optimized for AI assistants such as Claude, and can control hardware devices through natural language instructions.
Multiple data formats
Supports multiple data format encodings such as UTF - 8, Hex, and Binary, and can configure timeout processing.
High performance
Built on the Tokio asynchronous runtime, supporting high - concurrency connections and efficient data transmission.
Advantages
A ready - to - use production - level solution that has been verified by actual hardware.
A complete set of 5 serial port tools covering all basic communication needs.
Detailed STM32 demonstration cases to help you get started quickly.
Simple MCP protocol integration for seamless cooperation with AI assistants.
Supported by an active open - source community and continuously updated.
Limitations
Requires basic Rust knowledge for custom development.
Currently only supports serial communication and does not support other hardware interfaces.
Advanced functions require the support of hardware devices.

How to use

Installation preparation
Ensure that the Rust 1.70+ environment is installed, and prepare the hardware device and connection cables.
Get the project
Clone the GitHub repository and compile the project.
Configure the MCP client
Configure the MCP server path in AI assistants such as Claude.
Start using
Interact with hardware devices through natural language instructions.

Usage examples

Device discovery
Find the serial port devices connected to the current system
Device connection
Establish a serial port connection with the STM32 development board
LED control
Control the LED on the development board through the serial port
Data collection
Read data from the sensor
