Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| wechat_ideA | 微信开发者工具 IDE 生命周期管理。 支持 action: open(打开IDE/项目), login(扫码登录), is_login(检查登录), close(关闭项目), quit(退出IDE), status(环境诊断)。 返回 JSON: {success, data, message, error_code?}。 |
| wechat_buildB | 构建、预览、上传小程序及 npm 管理。 支持 action: compile(编译检查), preview(预览), upload(上传), build_npm(构建NPM), cache_clean(清缓存)。 返回 JSON: {success, data, message, error_code?}。 |
| wechat_automatorA | 小程序自动化交互与运行时查询。 支持 action: start(开启自动化), tap(点击), input(输入), element_info(元素信息), set_data(设置数据), call_method(调用方法), call_wx(调用wx API), mock_wx(Mock wx), evaluate(执行JS), page_stack(页面栈), page_data(页面数据), system_info(系统信息), storage(缓存)。 返回 JSON: {success, data, message, error_code?}。 |
| wechat_inspectorA | 采集小程序运行时日志和异常。 支持 action: console(automator端口采集console日志和JS异常), cdp(通过CDP协议采集WXML警告、渲染层报错、废弃API提示等底层日志)。 cdp action 需先以 cdp_enabled=true 打开项目，确保端口 9222 可用。 返回 JSON: {success, data: {logs, summary}, message}。 |
| wechat_screenshotA | 实时捕获当前小程序模拟器的界面截图。 默认支持截取长图，自动滚动并拼接。 output_path 可选，留空则自动保存到项目目录下 screenshots/ 文件夹。 返回 JSON: {success, data: {path, width, height, segments}, message}。 |
| wechat_navigateA | 跳转到指定页面，等待指定时间，通过 CDP 采集高清日志。 适用于页面生命周期日志检查（onLoad/onShow）、页面错误验证。 需先调用 wechat_automator(action='start') 并以 cdp_enabled=true 打开项目。 返回 JSON: {success, data: {current_page, cdp_logs}, message}。 |
| wechat_fileA | 读取小程序项目文件和结构信息。 支持 action: project_info(项目完整信息), list_pages(页面列表), read_page(读取页面源码), read_file(读取单个文件)。 返回 JSON: {success, data, message, error_code?}。 |

TDQS
Scored across 7 tools
The tools are mostly distinct by domain: IDE lifecycle, build/upload, automation, logging, navigation, file reading, and screenshots each have a clear role. There is some overlap between wechat_inspector and wechat_navigate because both collect CDP logs, and wechat_navigate depends on wechat_automator being started, but the descriptions make the intended boundaries reasonably clear.
All tools use a consistent wechat_ prefix and snake_case style, which makes the set predictable. The suffixes are mostly domain nouns (ide, build, automator, inspector, file) with one verb-like name (navigate), a minor deviation from an otherwise stable pattern.
Seven tools is well-scoped for a WeChat DevTools MCP server. Each tool represents a meaningful capability group with sub-actions, avoiding both a fragmented one-action-per-tool surface and an oversized tool list.
The surface covers the main developer workflow: IDE lifecycle, project/file inspection, build/preview/upload, screenshots, automation, navigation, and log collection. Minor gaps exist, such as no explicit automator stop/teardown action and no targeted element screenshot, but core workflows are well covered.
