Nabo MCP Lite
Provides tools for controlling a Chrome browser, including tab management (list, switch, open, close), navigation, page reading (DOM, text, screenshots), and page interaction (click, input, select, send keys, scroll, execute scripts).
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Nabo MCP Litelist all open tabs"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Nabo MCP Lite
一个精简的本地 MCP 浏览器控制桥接项目。它保留 Nanobrowser 操作 Chrome 网页所需的核心能力,移除了模型、Agent 编排、语音、界面和遥测等非必要模块。
架构
MCP Client(Claude / Codex / 其他客户端)
│ stdio MCP
▼
server/single-session-server.cjs
│ WebSocket 127.0.0.1:9876
▼
Nabo MCP Lite Chrome Extension
│ Chrome API / CDP

Chrome 网页标签页Related MCP server: Chrome MCP Server
功能
提供 14 个 MCP 工具:
标签页:
list_tabs、switch_tab、open_tab、close_tab导航:
navigate页面读取:
get_dom、get_page_text、screenshot页面操作:
click_element、input_text、select_option键盘和滚动:
send_keys、scroll脚本执行:
execute_script
get_page_text 最多返回 50,000 字符,并提供 truncated 和 originalLength,避免大型网页占满 Agent 上下文。
环境要求
Node.js 18+
pnpm
Google Chrome
支持 stdio MCP 的客户端
安装与构建
git clone https://github.com/kaleburannengsha-hue/nabo-mcp-lite.git
cd nabo-mcp-lite
pnpm install
pnpm test
pnpm type-check
pnpm build构建产物位于 dist/。
加载 Chrome 扩展
打开
chrome://extensions。开启“开发者模式”。
点击“加载已解压的扩展程序”。
选择项目的
dist目录。每次重新构建后,点击扩展卡片上的刷新按钮。
MCP 配置
Claude Desktop 示例见:
config/claude-desktop.example.json核心配置:
{
"mcpServers": {
"nanobrowser": {
"command": "node",
"args": [
"D:\\path\\to\\nabo-mcp-lite\\server\\single-session-server.cjs"
]
}
}
}Claude Code:
claude mcp add nanobrowser -- node D:\path\to\nabo-mcp-lite\server\single-session-server.cjs其他客户端可参考 config/mcp-stdio.example.json。
测试真实连接
确保 Chrome 已加载并刷新扩展,且没有其他进程占用 9876:
$env:IDLE_WAIT_MS = "2000"
node scripts/runtime-test.cjs成功输出应包含:
FIRST_CALL_OK
DOM_OK
PAGE_TEXT_OK
SECOND_CALL_OK
RUNTIME_TEST_OK使用限制
当前为单 Session 服务,同一时间只能有一个服务端监听 9876。
多个 MCP 客户端同时启动服务端会产生端口冲突。
chrome://内部页面受 Chrome 安全策略限制。execute_script可以执行网页脚本,只应连接可信的本地 MCP 客户端。
