A WeChat robot server that enables AI agents to send and receive messages.

mcp-wechat-server

基于 MCP(Model Context Protocol)的微信机器人服务器,让任何 AI Agent 都能收发微信消息。

功能

  • 6 个 MCP 工具:登录、消息轮询、文本发送、打字状态
  • 扫码登录:生成终端文本二维码、PNG 图片、URL 链接三种方式
  • 长轮询监听:阻塞等待新消息,最长可等待 7 天
  • 打字状态:Agent 处理消息时自动显示"对方正在输入..."
  • 状态持久化:重启不丢失登录凭证和消息游标
  • 独立运行:无需 OpenClaw 框架,开箱即用

      "args": ["mcp-wechat-server"]
    }
  }
}

  "mcp": {
    "wechat": {
      "type": "local",
      "command": ["bunx", "mcp-wechat-server"],
      "enabled": true
    }

环境要求

使用方法

1. 扫码登录

AI Agent 调用 login_qrcode 生成二维码,你可以通过以下方式扫码:

  • 在终端运行 cat ~/.mcp-wechat-server/qrcode.txt 查看二维码
  • 打开图片文件 ~/.mcp-wechat-server/qrcode.png
  • 将链接复制到微信中打开

提示:如果手机扫码后页面一直加载,请切换到移动数据网络(关闭 WiFi)。

2. 确认登录

Agent 调用 check_qrcode_status 确认登录状态。

3. 开始聊天

登录成功后,Agent 会自动执行以下流程:

  1. 调用 get_messages 轮询新消息
  2. 收到消息后调用 send_typing 显示"正在输入..."
  3. 处理完成后调用 send_text_message 回复
  4. 回复完毕后调用 send_typing 取消打字状态
