What is Puppeteer MCP?

Puppeteer MCP is a Model Context Protocol server that leverages Puppeteer (or its Python equivalent, Playwright) to provide robust browser automation capabilities. This server enables LLMs to navigate web pages, take screenshots, fill forms, and execute JavaScript in a real browser environment. It's ideal for automating web testing, scraping dynamic content, and capturing screenshots for documentation.

Key Features of Puppeteer MCP Explained

1. Advanced Browser Automation for Puppeteer MCP

Puppeteer MCP supercharges traditional browser automation by integrating AI capabilities:

• Natural Language Navigation: Instruct LLMs to "Go to GitHub, search for AI repos, and open the top 3 results"
• Smart Form Interaction: Automate complex form submissions with dynamic field detection
• Multi-step Workflows: Chain actions like login → data extraction → report generation in a single command

Pro Tip: Combine with Claude's reasoning to handle CAPTCHAs or consent dialogs intelligently.

2. Puppeteer MCP Intelligent Screenshot Capture

Beyond basic screenshots, Puppeteer MCP enables:

• Context-aware captures: "Take screenshot of pricing table on scroll-triggered lazy-loaded page"
• Visual diffing: Compare screenshots across deployments
• OCR integration: Extract text from images for further processing

Example Use Case: Automatically document UI states for accessibility compliance reports.

3. Dynamic JavaScript Execution using Puppeteer MCP

Unlock next-level automation with:

• LLM-generated scripts: "Write JS to extract all product SKUs from this e-commerce page"
• Real-time DOM manipulation: Modify live pages without manual coding
• Performance monitoring: Track metrics like Lighthouse scores during interactions

Security Note: Sandbox execution with --disable-setuid-sandbox flag for production.

4. Console Log Monitoring with Puppeteer MCP

Transform debugging with:

• AI-powered log analysis: "Find all 404 errors from last session"
• Pattern detection: Identify memory leaks across page navigations
• Automated reporting: Generate bug summaries from console output

5. Configurable Puppeteer MCP's Browser Options

Customize via environment variables:

export PUPPETEER_HEADLESS=false  # Visible browser
export PUPPETEER_SLOWMO=250      # Slow-motion demo mode
export PUPPETEER_TIMEOUT=60000    # Extended timeout

How to Get Started with Puppeteer MCP

Step 1: Install Puppeteer MCP Server

Install Globally via npm:

You can install the Puppeteer MCP server globally using npm:

npm install -g puppeteer-mcp-server

Run Directly with npx:

Alternatively, you can run it without installation using npx:

npx puppeteer-mcp-server

Install from Source:

1. Clone the GitHub repository, install dependencies, build, and run the server manually:

git clone https://github.com/merajmehrabi/puppeteer-mcp-server.git

The file structure should look something like this:

2. get into the project folder:

cd puppeteer-mcp-server

3. install all the projects dependencies:

npm install

4. build the project:

npm run build

5. run the server:

npm start

Step 2: Configure Puppeteer MCP with Claude

Locate Claude Configuration File:

Find the Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Windows: %APPDATA%\Claude\claude_desktop_config.json

Add Puppeteer MCP Configuration:

Open the configuration file and add the following to enable Puppeteer MCP:

{
  "mcpServers": {
    "puppeteer": {
      "command": "puppeteer-mcp-server",
      "args": [],
      "env": {}
    }
  }
}

If using npx:

{
  "mcpServers": {
    "puppeteer": {
      "command": "npx",
      "args": ["-y", "puppeteer-mcp-server"],
      "env": {}
    }
  }
}

Step 3: Test Puppeteer MCP

Launch Claude:

Start the Claude Desktop App.

Verify Puppeteer MCP:

Check if the Puppeteer MCP server is recognized by Claude. You should see it listed in the tools section.

Clicking the icon will review Claudes available MCP servers.

To use Puppeteer MCP's console log resource, click "Choose integration" and select puppeteer mcp's console log resource.

You should see it available your chat.

Run Sample Commands:

Test the server by running sample commands, such as navigating to a URL or capturing a screenshot:

>> Navigate to https://example.com using Puppeteer. Capture a screenshot of the page.

Your commands can be as complex as possible! Claude is able to use the Puppeteer MCP Server to carry out even some of the most complex tasks you could have. For example:

>> Navigate to the website http://Any_Test_Website_Your_Want.com and click the login link. In the login page, enter the username and password as "admin" and "incorrect" respectively and perform login. Then click the Employee List page and click the "Create New" button and enter realistic employee details to create a new employee with the following details: Name, Salary, DurationWorked, and Email. Once created, try to log-out of the site.

Once you run the prompt, Claude will automatically open the browser and navigate to the specified website: "http://Any_Test_Website_You_Want.com". It will then click the login button, enter the credentials (username: "admin", password: "incorrect"), and log in. After successfully accessing the site, it will create a new employee with mock data and then log out.
