What the publisher says

From the Wechat Devtools repository's README, as published. We do not edit it. Read it on GitHub

微信开发者工具 MCP Server (v0.9.18)

把微信开发者工具封装为 MCP 服务，让编辑器里的 AI 直接完成小程序的编译、预览、调试、自动化测试闭环。Windows / macOS，已上架官方 MCP Registry。

<!-- mcp-name: io.github.WaterTian/wechat-devtools-mcp -->

[!IMPORTANT]

「瘦 MCP + 胖 Skill」：MCP Server 只提供 7 个聚合工具，操作流程与最佳实践都在配套的 wechat-devtools Skill 里。两者必须一起装。

🤝 与官方能力的关系

微信开发者工具 2.x 自 2026-08-18 起为官方 Stable（1.06 已下架），IDE 内建 MCP Server（47 个原子工具）。两者互补，不是替代：

⚠ 官方 IDE 把自家 bridge 注册为 wechat-devtools。本文示例统一用 wechat-devtools-mcp 避免撞名；旧名配置仍可用，只在同一 agent 同时接入两者时才需区分。

🚀 快速开始

Step 1 — 安装 MCP Server

pip install uv                                  # 如已装可跳过
uv tool install wechat-devtools-mcp --force
wechat-devtools-mcp --version                   # 确认实际运行版本

[!WARNING]

曾用 pip install 装过旧版的，先 pip uninstall wechat-devtools-mcp，否则旧路径优先于 uv。

≤0.9.10 与 mcp SDK ≥2.0 不兼容（报 ModuleNotFoundError: mcp.server.fastmcp），请升到 ≥0.9.11。

升级前先停掉编辑器里正在跑的 MCP 进程，再 uv tool upgrade wechat-devtools-mcp。

Step 2 — 开启开发者工具服务端口

开发者工具 → 设置 → 安全设置 → 服务端口 → 开启。不开则所有操作报 CLI_TIMEOUT。

Step 3 — 准备两个绝对路径

JSON 里 Windows 路径的 \ 要写成 \\；macOS 的 / 不用转义。

Step 4 — 编辑器配置

标准配置（Claude Desktop / Antigravity / Kiro / Trae / Claude Code .mcp.json 通用）：

{
  "mcpServers": {
    "wechat-devtools-mcp": {
      "command": "uvx",
      "args": ["wechat-devtools-mcp"],
      "env": {
        "WECHAT_DEVTOOLS_CLI": "C:\\Program Files (x86)\\Tencent\\微信web开发者工具\\cli.bat",
        "WECHAT_PROJECT_PATH": "D:\\Your\\Project\\Path"
      }
    }
  }
}
[mcp_servers.wechat-devtools-mcp]
command = "uvx"
args = ["wechat-devtools-mcp"]

[mcp_servers.wechat-devtools-mcp.env]
WECHAT_DEVTOOLS_CLI = "C:\\Program Files (x86)\\Tencent\\微信web开发者工具\\cli.bat"
WECHAT_PROJECT_PATH = "D:\\Your\\Project\\Path"
