Overview

What is MCP Server for sensor device?

MCP Server for sensor device is a Node.js application designed for use with Claude Desktop. It simulates a CO2 sensor device and provides a JSON-RPC server to interact with the device, supporting both simulation mode and real mode where it connects to a Raspberry Pi Pico via USB to read actual CO2 levels.

How to use MCP Server for sensor device?

Install Node.js, clone the repository, run npm install to install dependencies, then configure claude_desktop_config.json with the server command and path. Start the server by running node index.js in the project directory.

Key features of MCP Server for sensor device
