ESP32 Runs MCP-Enabled Voice Assistant for Home Automation

A tutorial shows how to build a voice-controlled AI assistant using a DFRobot ESP32-S3 AI Cam and Xiaozhi firmware, demonstrating Model Context Protocol (MCP) to safely control hardware and software automations. The guide provides step-by-step CAD and 3D printing files, firmware flashing, wiring, enclosure assembly, and MCP configuration for LED, DHT11 sensor, and Google Calendar integrations. It emphasizes structured JSON tool schemas and server-side validation so the AI issues deterministic, validated commands rather than guesses.
