FastMCP-Sensor-Controller

# FastMCP Sensor Controller This project is an experimental server for controlling sensors and LEDs via MCP using ESP32 (MicroPython) and MQTT. By replacing the MQTT server with Azure IoT Hub, you can also communicate with the microcontroller over the internet. FastMCP documentation: https://gofastmcp.com/getting-started/welcome ## ✅ Configuration  - ESP32 (MicroPython): - Microcontroller - ESP32-DevKit (※ with technical certification mark) - https://amzn.to/4iWmr4s - Parts - DHT11 temperature and humidity sensor ※DHT11 module - https://amzn.to/43jR2n8 - RGB LED (GPIO 13, 12, 16) ※KY-016 - https://amzn.to/4mbcnYp - Role - Receive and respond to commands via MQTT - FastMCP: - Send commands to MQTT via SSE - Can acquire sensor data and control LEDs ## 🚀 Startup Method (MCP Server & MQTT Broker) ```bash docker compose up -d ``` ## 💾 Writing to MicroPython Refer to the following for installing MicroPython on ESP32. https://zenn.dev/kotaproj/articles/d969fb39100da443f41f Upload `main.py` in the `esp32_micropython` folder to ESP32. (It is convenient to use an IDE such as Thonny) ## 🧪 ClaudeDesktop (MCP Client) Settings ```json { "mcpServers": { "sensorController": { "command": "npx", "args": [ "mcp-remote", "http://127.0.0.1:8888/sse" ] } } } ```
