Wechat Server — Model Context Protocol server
README
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
快速开始
Claude Desktop
在 claude_desktop_config.json 中添加:
{
"mcpServers": {
"wechat": {
"command": "bunx",
"args": ["mcp-wechat-server"]
}
}
}
OpenCode
在 opencode.json 中添加:
{
"mcp": {
"wechat": {
"type": "local",
"command": ["bunx", "mcp-wechat-server"],
"enabled": true
}
}
}
Cursor / 其他 MCP 客户端
{
"command": "bunx",
"args": ["mcp-wechat-server"]
}
bunx会自动从 npm 下载并运行,无需手动安装。
环境要求
- Bun >= 1.0.0
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:
- 调用
get_messages轮询新消息 - 收到消息后调用
send_typing显示"正在输入..." - 处理完成后调用
send_text_message回复 - 回复完毕后调用
send_typing取消打字状态
