Playwright MCP-Server 🎭

Schmiedeabzeichen

Ein Model Context Protocol-Server, der Browser-Automatisierungsfunktionen mit Playwright bereitstellt. Dieser Server ermöglicht LLMs die Interaktion mit Webseiten, das Erstellen von Screenshots, das Generieren von Testcode, das Web Scraping der Seite und die Ausführung von JavaScript in einer realen Browserumgebung.

Installation

Sie können das Paket entweder mit npm, mcp-get oder Smithery installieren:

Verwenden von npm:

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

Verwenden von mcp-get:

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

Schmiedekunst verwenden

So installieren Sie Playwright MCP für Claude Desktop automatisch über Smithery :

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

Installation in VS Code

Installieren Sie den Playwright MCP-Server in VS Code mit einer dieser Schaltflächen:

Alternativ können Sie den Playwright MCP-Server mithilfe der VS Code CLI installieren:

# 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"]}'

Nach der Installation steht der ExecuteAutomation Playwright MCP-Server zur Verwendung mit Ihrem GitHub Copilot-Agent in VS Code zur Verfügung.

Konfiguration zur Verwendung von Playwright Server

Hier ist die Claude Desktop-Konfiguration zur Verwendung des Playwright-Servers:

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

Testen

Dieses Projekt verwendet Jest zum Testen. Die Tests befinden sich im Verzeichnis src/__tests__ .

Ausführen von Tests

Sie können die Tests mit einem der folgenden Befehle ausführen:

# 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)

Der Testabdeckungsbericht wird im coverage generiert.

Ausführen von Evaluierungen

Das Evals-Paket lädt einen MCP-Client, der anschließend die Datei index.ts ausführt, sodass zwischen den Tests kein Neuaufbau erforderlich ist. Sie können Umgebungsvariablen laden, indem Sie dem Befehl npx voranstellen. Die vollständige Dokumentation finden Sie hier .

    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.
