### Description (declared)

# wechat-mcp-macos

An MCP (Model Context Protocol) server that lets AI assistants read, monitor, and send WeChat messages on macOS. Supports continuous conversation polling — your AI can watch group chats and auto-reply.

Works with Claude Code, Claude Desktop, and any MCP-compatible client.

一个 MCP 服务器，让 AI 助手在 macOS 上读取、监控和发送微信消息。支持持续对话轮询——让你的 AI 盯着群聊自动回复。

## How It Works / 工作原理

**Reading messages**: Decrypts the local WeChat SQLite database (SQLCipher 4, AES-256-CBC) and queries it directly. This is fast, accurate, and doesn't require screenshots or OCR.

**Sending messages**: Uses macOS `osascript` (AppleScript) to automate the WeChat desktop client — sets the clipboard, clicks the input box, pastes, and hits Enter.

**读取消息**：解密本地微信 SQLite 数据库（SQLCipher 4, AES-256-CBC）并直接查询。速度快、准确率 100%，不需要截图或 OCR。

**发送消息**：通过 macOS `osascript`（AppleScript）自动化微信桌面客户端——设置剪贴板、点击输入框、粘贴、回车发送。

## Requirements / 环境要求

- macOS (tested on macOS 15 Sequoia)

## First-Time Setup / 首次配置

The first time you use it, you need to set up WeChat database access:

首次使用需要配置微信数据库访问：

### 1. Re-sign WeChat / 重签名微信

WeChat ships with hardened runtime, which prevents memory scanning for encryption keys. You need to re-sign it:

微信自带 hardened runtime，需要重签名才能提取密钥：

```
# Quit WeChat first! / 先退出微信！
# Then ask your AI to run:
setup("sign")
```

Or manually:
```bash
sudo codesign --force --deep --sign - /Applications/WeChat.app
```

> **Note**: After re-signing, you may need to …
