## Description

Demonstrates the difference between OpenAI function calling and the Model Context Protocol by implementing two approaches to controlling Home Assistant lights. The function calling implementation uses OpenAI's direct function invocation method, while the MCP server provides a standardized protocol for light control that can be used by any MCP-compatible AI assistant. Serves as an educational comparison of different AI interaction paradigms in home automation.
