## Description

A WeChat Mini Program automation server that provides programmatic control over WeChat DevTools through the miniprogram-automator library. The FastMCP-based implementation exposes tools for application lifecycle management (launching, connecting, closing), page navigation and interaction, and element manipulation including querying, clicking, typing, and attribute reading. It supports both launch mode for starting new DevTools instances and connect mode for attaching to existing WebSocket endpoints, with comprehensive configuration through environment variables or runtime parameters. The server handles connection management, element resolution with nested selectors, and proper serialization of WeChat-specific data structures, making it useful for automated testing of Mini Programs, UI automation workflows, and integration testing in WeChat development pipelines.
