剧作家 MCP 服务器🎭

铁匠徽章

一个使用 Playwright 提供浏览器自动化功能的模型上下文协议 (MLM) 服务器。该服务器使 LLM 能够与网页交互、截取屏幕截图、生成测试代码、从网页中提取网页数据,并在真实的浏览器环境中执行 JavaScript。

安装

您可以使用 npm、mcp-get 或 Smithery 安装该软件包:

使用 npm:

npm install -g @executeautomation/playwright-mcp-server

使用 mcp-get:

npx @michaellatman/mcp-get@latest install @executeautomation/playwright-mcp-server

使用 Smithery

要通过Smithery自动为 Claude Desktop 安装 Playwright MCP:

npx @smithery/cli install @executeautomation/playwright-mcp-server --client claude

在 VS Code 中安装

使用以下按钮之一在 VS Code 中安装 Playwright MCP 服务器:

或者,您可以使用 VS Code CLI 安装 Playwright MCP 服务器:

# For VS Code
code --add-mcp '{"name":"playwright","command":"npx","args":["@executeautomation/playwright-mcp-server"]}'
# For VS Code Insiders
code-insiders --add-mcp '{"name":"playwright","command":"npx","args":["@executeautomation/playwright-mcp-server"]}'

安装后,ExecuteAutomation Playwright MCP 服务器将可与 VS Code 中的 GitHub Copilot 代理一起使用。

使用 Playwright Server 的配置

以下是使用 Playwright 服务器的 Claude Desktop 配置:

{
  "mcpServers": {
    "playwright": {
      "command": "npx",
      "args": ["-y", "@executeautomation/playwright-mcp-server"]
    }
  }
}

测试

该项目使用 Jest 进行测试。测试位于src/__tests__目录中。

运行测试

您可以使用以下命令之一运行测试:

# Run tests using the custom script (with coverage)
node run-tests.cjs

# Run tests using npm scripts
npm test           # Run tests without coverage
npm run test:coverage  # Run tests with coverage
npm run test:custom    # Run tests with custom script (same as node run-tests.cjs)

测试覆盖率报告将在coverage目录中生成。

运行评估

evals 包会加载一个 mcp 客户端,然后运行 index.ts 文件,因此测试之间无需重新构建。您可以通过在 npx 命令前添加前缀来加载环境变量。完整文档可在此处找到。

OPENAI_API_KEY=your-key  npx mcp-eval src/evals/evals.ts src/tools/codegen/index.ts

    B3.3/5.0

    Scored across 32 tools

    Disambiguation4/5

    Most tools have distinct purposes, with clear separation between navigation, interaction, HTTP requests, and code generation functions. However, some overlap exists between playwright_click and playwright_iframe_click, and between playwright_fill and playwright_iframe_fill, which could cause minor confusion about when to use the iframe variants versus regular versions.

    Naming Consistency5/5

    Excellent naming consistency throughout. All tools follow a clear snake_case pattern with 'playwright_' prefix for browser operations and descriptive verb_noun combinations. The three codegen tools also follow a consistent pattern with 'codegen_session' suffix.

    Tool Count3/5

    32 tools is quite large for an MCP server, bordering on heavy. While Playwright is a comprehensive browser automation library, this many tools may overwhelm agents and could potentially be consolidated (e.g., HTTP methods could be a single tool with method parameter).

    Completeness5/5

    The tool surface provides comprehensive coverage of Playwright's core functionality including navigation, element interaction, iframe handling, HTTP requests, debugging (console logs), file operations, PDF/screenshot generation, and code generation. No obvious gaps exist for typical browser automation workflows.
