mcp-connected-hearts

this is a MCP tool to control a Wi-Fi-connected ESP32 Heart PCB with AI assistants like Claude

This tool is part of my personal project Connected Heart, which I built for Highway.
It lets AI talk to the heart and make it feel alive!!! yayyyy

What it can do

• Show text on the OLED
• Set RGB lights (named colors or custom values)
• Trigger a buzzer
• Read the state of 4 buttons

Getting Started

Make sure your ESP32 is running the heart firmware and connected to Wi-Fi.

Then run:

npx mcp-connected-hearts

Use it with Claude

1. Open Settings → Developer → Edit Config
2. Add this to your config:

{
  "mcpServers": {
    "hearts": {
      "command": "npx",
      "args": ["mcp-connected-hearts"]
    }
  }
}

3. Save the file and restart Claude

What you can ask Claude

Once everything’s connected, try saying things like:

• Show I love AI on heart
• Make the heart glow blue
• Buzz the heart
• What buttons are being pressed?
• Set the RGB to 255, 100, 50
