- Simulates a CO2 sensor device with random CO2 levels in simulation mode.
- Connects to a Raspberry Pi Pico via USB to read real CO2 levels.
- Provides device information, sensor data, and network status via JSON-RPC.
- Supports commands to publish data to MQTT, reconnect WiFi, and reconnect MQTT (some functionalities are mocked).
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
CO2 SensorCommand (node, npx, python, etc.)nodeArguments-
Argument 1
...mcp-server-for-sensor-device/index.js
Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.

}MCP Server for sensor device
This project 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. The application can run in both simulation mode and real mode, where it connects to a Raspberry Pi Pico via USB to read CO2 levels.
Features
- Simulates a CO2 sensor device with random CO2 levels in simulation mode.
- Connects to a Raspberry Pi Pico via USB to read real CO2 levels.
- Provides device information, sensor data, and network status via JSON-RPC.
- Supports commands to publish data to MQTT, reconnect WiFi, and reconnect MQTT (some functionalities are mocked).
Installation
You need to have Node.js installed on your machine to run this application. If you don't have Node.js installed, you can download it from the official website.
1. Clone the repository.
2. Install the dependencies using npm:
npm install
Configuration
Ensure that the claude_desktop_config.json file is correctly configured to run the server. Example configuration:
{
"mcpServers": {
"CO2 sensor": {
"command": "node",
"args": [
"...mcp-server-for-sensor-device/index.js"
],
"env": {}
}
}
}
Usage
To start the server, run the following command:
node index.js
JSON-RPC Methods
initialize
Initializes the server and returns server capabilities.
shutdown
Shuts down the server.
resources/list
Lists available resources.
resources/read
Reads the specified resource.
tools/list
Lists available tools.
tools/call
Calls the specified tool.
DeviceState Class
The DeviceState class simulates the device state and provides methods to get device information, sensor data, and network status. It also handles the connection to the Raspberry Pi Pico and reads CO2 levels.
Methods
- getDeviceInfo(): Returns device information.
- getSensorData(): Returns sensor data.
- getNetworkStatus(): Returns network status (mocked functionality).
- publishToMQTT(): Simulates publishing data to MQTT (mocked functionality).
- reconnectWiFi(): Simulates reconnecting to WiFi (mocked functionality).
- reconnectMQTT(): Simulates reconnecting to MQTT (mocked functionality).
Logging
The application logs CO2 levels and other information to a log file located in the user's home directory (co2_level.log).
