🎮 Nordic Thingy:52 MCP Server

Control your Nordic Thingy:52 IoT device directly from Claude Desktop using the Model Context Protocol (MCP)

Transform your Claude Desktop into an IoT control center! This MCP server enables Claude to discover, connect to, and control Nordic Thingy:52 devices via Bluetooth LE - all through natural language conversation.

✨ Features

• 🔍 Auto-Discovery: Scan for nearby Thingy devices

• 🔌 Easy Connection: Connect via Bluetooth LE with a single command

• 💡 LED Control: Set RGB colors, create lighting effects

• 🔊 Sound Control: Play built-in sounds and tones

• 📊 Sensor Reading: Monitor temperature, humidity, pressure, CO2, and TVOC

• 🤖 AI Integration: Control everything through natural Claude conversations

• 🔄 Real-time Updates: Instant feedback and status monitoring

📋 Prerequisites

Hardware

• Nordic Thingy:52 device (Purchase here)

• Computer with Bluetooth LE support

• Battery or USB power for Thingy

Software

• Python 3.10 or higher

• Claude Desktop app (Download here)

• macOS (tested) or Linux with BlueZ (Windows support via bleak)

🚀 Quick Start

1. Installation

# Clone the repository
git clone https://github.com/yourusername/mcp-server-nordic-thingy.git
cd mcp-server-nordic-thingy

# Create virtual environment
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt

2. Configure Claude Desktop

Add the server to your Claude Desktop configuration:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "nordic-thingy": {
      "command": "python3",
      "args": ["/absolute/path/to/mcp_server_nordic_thingy.py"]
    }
  }
}

3. Restart Claude Desktop

Close and reopen Claude Desktop to load the server.

4. Start Using!

Try these prompts in Claude:

"Find my Nordic Thingy and connect to it"
"Turn the Thingy LED red"
"Check the temperature and air quality"
"Play a beep sound"

📖 Documentation

Available Tools

Sensor Data

The Thingy:52 provides:

• 🌡️ Temperature (°C)

• 💧 Humidity (%)

• 🔽 Pressure (hPa)

• 🌫️ CO2 (ppm) - Air quality

• 🌬️ TVOC (ppb) - Volatile organic compounds

• 🎨 Color sensor (RGB + Clear)

🎯 Example Use Cases

1. Home Office Monitor

"Monitor my office air quality. Check CO2 every 5 minutes and alert me if it's unhealthy (>1000 ppm)"

2. Smart Notifications

"When you detect motion (temperature change), flash the LED blue and beep twice"

3. Temperature Alerts

"If the temperature goes above 25°C, set the LED to red and play sound 5"

4. Mood Lighting

"Create a relaxing atmosphere: set the LED to a calm blue color"

5. Meeting Room Status

"Create a meeting room indicator:
- Green LED: Good air quality, room available
- Yellow LED: Moderate air quality
- Red LED: Poor air quality, needs ventilation"

🐛 Troubleshooting

Thingy Not Found

1. Check Power: Ensure Thingy is powered on (blue LED should pulse)

2. Bluetooth: Enable Bluetooth on your computer

3. Distance: Keep Thingy within 10 meters

4. Interference: Move away from other Bluetooth devices

5. Reset: Hold Thingy button for 5 seconds to reset

Connection Failed

# Check Bluetooth status
hcitool dev  # Linux
system_profiler SPBluetoothDataType  # macOS

# Scan manually
hcitool lescan  # Linux

# Reset Bluetooth (macOS)
sudo pkill bluetoothd

Claude Can't Find Server

1. Check claude_desktop_config.json path is correct

2. Verify Python path: which python3

3. Check server logs in Claude Desktop Developer Tools

4. Restart Claude Desktop
