playwright-mcp

What This Skill Does

The playwright-mcp skill is a powerful automation engine designed for OpenClaw agents to interact with the web just like a human. By leveraging the Playwright browser automation framework via the Model Context Protocol (MCP), it enables your agent to navigate complex websites, authenticate, perform form-based workflows, and extract structured data from virtually any page. Whether you are automating routine data entry, scraping dynamic content, or testing web application flows, this skill provides a robust, headless or headed browser environment to handle the underlying complexities of modern web technologies.

Installation

To get started, ensure you have Node.js installed in your environment. You can install the server globally using npm:

npm install -g @playwright/mcp

Before running it for the first time, you must install the necessary browser binaries to ensure compatibility:

npx playwright install chromium

You can then run the server via CLI using npx @playwright/mcp. For production environments, ensure the OpenClaw agent has the appropriate path configured to execute the binary securely.

Use Cases

This skill is ideal for:

• Automated Data Harvesting: Navigate to paginated sites, extract table data via JavaScript evaluation, and compile it into clean JSON.
• Complex Form Workflows: Automate registration or submission processes on sites that require multi-step form entry and validation.
• Verification and Testing: Validate page titles, content accessibility, or ensure specific elements appear after asynchronous content loading.
• Agentic Research: Use the agent to browse multiple sources, take snapshots for visual context, and synthesize information into a single report.

Example Prompts

1. "Open https://example.com, find the search box, type 'OpenClaw Documentation', and tell me the first three search result titles."
2. "Go to the dashboard at https://app.example.com/login, fill in the credentials, and extract the latest billing status from the table."
3. "Navigate to https://tech-news.com and take a snapshot of the main article area to help me understand the layout."

Tips & Limitations

• Security: Be mindful that browser automation can access sensitive sites; use --allowed-hosts to restrict access to trusted domains only.
• Resource Usage: Browsers are memory-intensive. Always use the --headless flag for background tasks to conserve system resources.
• Timeouts: If you are working with slow-loading sites, adjust the --timeout-navigation setting to prevent premature failure of your automation scripts.
• Anti-Bot Measures: Some websites employ aggressive websites block automation; while the browser mimics a real user, consider configuring the --user-agent to appear more standard if you encounter access issues.
