Documentation
Playwright Server MCP
> 一个基于Playwright的MCP服务器,提供浏览器自动化能力
组件
资源
服务器实现了简单的笔记存储系统:
- 自定义note://URI方案用于访问单个笔记
- 每个笔记资源具有名称、描述和text/plain MIME类型
提示
服务器提供单个提示功能:
- summarize-notes: 创建所有存储笔记的摘要
- 可选"style"参数控制详细程度(brief/detailed)
- 生成结合所有当前笔记与样式偏好的提示
工具
服务器实现以下Playwright相关工具:
会话与导航
- `playwright_new_session`: 创建新的浏览器会话并打开浏览器窗口
- 可选`url`参数(字符串),指定初始访问网址,不填则只打开浏览器
- `playwright_navigate`: 导航到指定网址
- 需要`url`参数(字符串),如不包含http或https前缀将自动添加https://
- 如果没有活跃的浏览器会话,会自动创建一个新会话
页面交互与获取内容
- `playwright_screenshot`: 对当前页面或特定元素进行截图
- 需要`name`参数(字符串),截图文件名称,不需要包含扩展名
- 可选`selector`参数(字符串),CSS选择器用于指定要截图的页面元素,不填则截取整个页面
- `playwright_evaluate`: 在浏览器控制台中执行JavaScript代码
- 需要`script`参数(字符串),需要在浏览器中执行的JavaScript代码
- `playwright_get_text_content`: 获取当前页面中所有可见元素的文本内容
- 无需参数
- 智能过滤重复内容,只返回有意义的文本
- `playwright_get_html_content`: 获取页面中指定元素的HTML内容
- 需要`selector`参数(字符串),CSS选择器用于定位需要获取HTML内容的页面元素
高级交互操作
- `playwright_action`: 支持丰富的元素选择与交互方式
- 必需参数:
- `by`: 选择元素方式,支持get_by_text、get_by_placeholder、get_by_label、get_by_role等
- `by_value`: 选择元素的值
- `action`: 操作类型,如fill、click、dblclick、hover、check等
- 可选参数:
- `value`: 操作的值
- `force`: 是否强制执行动作
- `delay`: 按键之间的延迟(毫秒)
- 以及更多专用参数,参见代码文档
- 必需参数:

安装
Claude Desktop配置
MacOS: `~/Library/Application\ Support/Claude/claude_desktop_config.json`
Windows: `%APPDATA%/Claude/claude_desktop_config.json`
开发/未发布服务器配置
"mcpServers": {
"playwright-server": {
"command": "uv",
"args": [
"--directory",
"C:\\Users\\xxxxx\\Documents\\project\\python\\mcp\\playwright-server",
"run",
"playwright-server"
]
}
}已发布服务器配置
"mcpServers": {
"playwright-server": {
"command": "uvx",
"args": [
"playwright-server"
]
}
}开发
构建与发布
准备发布包:
1. 同步依赖并更新锁定文件:
uv sync2. 构建包分发:
uv build这将在`dist/`目录中创建源代码和wheel分发。
3. 发布到PyPI:
uv publish注意: 您需要通过环境变量或命令参数设置PyPI凭据:
- 令牌: `--token`或`UV_PUBLISH_TOKEN`
- 或用户名/密码: `--username`/`UV_PUBLISH_USERNAME`和`--password`/`UV_PUBLISH_PASSWORD`
调试
由于MCP服务器通过stdio运行,调试可能具有挑战性。为获得最佳调试体验,我们强烈推荐使用MCP Inspector。
您可以通过`npm`使用以下命令启动MCP Inspector:
npx @modelcontextprotocol/inspector uv --directory C:\Users\xxxxx\Documents\project\python\mcp\playwright-server run playwright-server启动后,Inspector将显示一个URL,您可以在浏览器中访问该URL开始调试。
使用示例
基本网页访问与截图
# 创建会话并导航到指定网址
await playwright_navigate(url="example.com")
# 截取整个页面
await playwright_screenshot(name="fullpage")
# 截取特定元素
await playwright_screenshot(name="logo", selector=".logo")高级交互操作
# 点击文本匹配的按钮
await playwright_action(by="get_by_text", by_value="登录", action="click")
# 填充表单字段
await playwright_action(by="get_by_placeholder", by_value="用户名", action="fill", value="test@example.com")
# 检查元素是否可见
await playwright_action(by="get_by_test_id", by_value="submit-button", action="is_visible")Frequently asked questions
