MCP LEDAPI Intent Controller

This project implements a Model Context Protocol (MCP)-style server using FastAPI to control an Arduino-based LED system via a RESTful interface. For best results, use this together with the MCPForLedAPI project. It interprets high-level intents like TurnOnLed, SetMood, or GetStatus, and translates them into commands for the Arduino LED API.

Features

Supports contextual LED control via structured intents
Communicates with an Arduino LED controller API (/setLedStatus, /status)
Automatically exposes Swagger UI for testing
Extensible architecture for adding new devices or control logic

Intents Supported

Intent	Description	Parameters
TurnOnLed	Turns on a specific LED	`{ "color": "red" }`
TurnOffLed	Turns off all LEDs	`none`
SetPattern	Sets specific LED pattern	`{ "pattern": "1100" }`
SetMood	Uses predefined mood pattern	`{ "mood": "calm" }`
PowerDown	Alias for turning everything off	`none`
GetStatus	Queries the current LED state	`none`

Example Requests

POST /intent
{
  "intent": "TurnOnLed",
  "parameters": {
    "color": "green"
  }
}

POST /intent
{
  "intent": "SetMood",
  "parameters": {
    "mood": "calm"
  }
}
