WinAutoWx is a Python-based automation script leveraging `pywinauto` to interact with the Windows version of WeChat (Weixin/WeChat). It enables users to programmatically launch WeChat, search for specific friends or group chats, and send multiple messages in a loop to various contacts. Designed with support for LLM (Large Language Model) integration via its MCP (Model Context Protocol) compatibility, WinAutoWx provides both a FastAPI-based HTTP API and a fastmcp-compatible stdio server, making it a versatile tool for enhancing personal productivity and automating repetitive WeChat tasks.
