An MCP-based Chatbot

(English | 中文 | 日本語)

Introduction

👉 Human: Give AI a camera vs AI: Instantly finds out the owner hasn't washed hair for three days【bilibili】

👉 Handcraft your AI girlfriend, beginner's guide【bilibili】

As a voice interaction entry, the XiaoZhi AI chatbot leverages the AI capabilities of large models like Qwen / DeepSeek, and achieves multi-terminal control via the MCP protocol.

Version Notes

The current v2 version is incompatible with the v1 partition table, so it is not possible to upgrade from v1 to v2 via OTA. For partition table details, see partitions/v2/README.md.

All hardware running v1 can be upgraded to v2 by manually flashing the firmware.

The stable version of v1 is 1.9.2. You can switch to v1 by running git checkout v1. The v1 branch will be maintained until February 2026.

Software

Firmware Flashing

For beginners, it is recommended to use the firmware that can be flashed without setting up a development environment.

The firmware connects to the official xiaozhi.me server by default. Personal users can register an account to use the Qwen real-time model for free.

👉 Beginner's Firmware Flashing Guide

Development Environment

Cursor or VSCode

Install ESP-IDF plugin, select SDK version 5.4 or above

Linux is better than Windows for faster compilation and fewer driver issues

This project uses Google C++ code style, please ensure compliance when submitting code
