## What it is
A self-hosted backend server for the xiaozhi-esp32 open-source smart hardware project, implementing the Xiaozhi communication protocol over MQTT+UDP and WebSocket. It supports MCP access points, voiceprint recognition, and knowledge bases, enabling users to run their own ESP32 voice assistant control server.

## Use cases
- self-host a backend server for xiaozhi-esp32 devices
- build a voice assistant server for ESP32 hardware
- control ESP32 devices with a custom AI backend
- add voiceprint recognition to an ESP32 voice assistant
- connect a knowledge base to an ESP32 chatbot
- run an MCP access point for smart hardware

## When to choose
- you own xiaozhi-esp32 hardware and want your own backend instead of the shared public server
- you need privacy and full control over your voice assistant data
- you want to integrate custom LLMs, TTS, or knowledge bases with ESP32 devices

## When to avoid
- you don't have ESP32 hardware or aren't using the xiaozhi-esp32 firmware
- you want a turnkey commercial voice assistant without self-hosting
- you need a backend for other IoT protocols unrelated to the Xiaozhi protocol
