等待文字消失:
browser_wait_for(text: "加载中...", waitForGone: true)
等待指定时间:
browser_wait_for(timeout: 3000)
锁定/解锁
锁定浏览器(防止误操作):
browser_lock()
解锁浏览器:
browser_unlock()
环境要求
- Node.js 16+
- 支持的操作系统:Linux、macOS、Windows
技术栈
- Puppeteer - 浏览器自动化
- @modelcontextprotocol/sdk - MCP 协议支持
- TypeScript - 类型安全
配置选项
默认使用 Headless 模式运行(无图形界面)。如需可视化模式,可修改 src/browser.ts 中的 headless 选项:
this.browser = await puppeteer.launch({
headless: false, // 改为 false 可启用可视化模式
// ...
});
故障排除
1. 浏览器启动失败
错误信息:Missing X server or $DISPLAY
解决方案:确保使用 Headless 模式(默认已启用)。
2. 找不到模块
错误信息:Cannot find module
解决方案:
cd /home/lpsadmin/work/mcp-cursor-ide-browser
npm install
npm run build
3. 权限问题
错误信息:EACCES: permission denied
解决方案:
chmod +x /home/lpsadmin/work/mcp-cursor-ide-browser/dist/index.js
