Browser Agent MCP Server

A Model Context Protocol (MCP) server that provides browser automation capabilities through Claude Desktop and other MCP clients.

Features

• 🌐 Browser Automation: Control web browsers programmatically
• 🎯 Multiple Engines: Support for Playwright and Selenium
• 📸 Screenshot Capture: Take screenshots of web pages
• 🔍 Content Extraction: Extract text and HTML content
• 🖱️ Interactive Control: Click, type, scroll, and navigate
• ⚡ Fast Setup: One-click startup with uv
• 🔧 Flexible Configuration: Environment variables and command-line options

Quick Start

1. Install Dependencies

# Install uv if not already installed
curl -LsSf https://astral.sh/uv/install.sh | sh

# Clone and setup the project
git clone <your-repo-url>
cd browser-agent

# Install dependencies and browsers
uv sync
uv run playwright install

2. One-Click Startup

# Start the MCP server
uv run python start.py

Claude Desktop Configuration

1. Install uv

Make sure uv is installed on your system: ``bash curl -LsSf https://astral.sh/uv/install.sh | sh ``

2. Add Browser Agent Server

Option A: From GitHub Repository (Recommended) Use this configuration to run directly from your GitHub repository:

{
  "mcpServers": {
    "browser-agent": {
      "command": "uv",
      "args": [
        "run",
        "--from",
        "git+https://github.com/galilio/browser-mcp.git",
        "python",
        "start.py"
      ],
      "env": {
        "BROWSER_ENGINE": "playwright",
        "BROWSER_HEADLESS": "false",
        "BROWSER_TIMEOUT": "30000"
      }
    }
  }
}

Option B: Generate GitHub Configuration Run the GitHub configuration generator:

uv run python generate_github_config.py

Option C: Generate Local Configuration Run the configuration generator to get the correct local paths:

uv run python generate_config.py

Option D: Manual Local Configuration Add the following configuration to your MCP servers (replace the path with your actual project directory):

{
  "mcpServers": {
    "browser-agent": {
      "command": "uv",
      "args": ["run", "python", "/path/to/your/browser-agent/start.py"],
      "env": {
        "BROWSER_ENGINE": "playwright",
        "BROWSER_HEADLESS": "false",
        "BROWSER_TIMEOUT": "30000",
        "BROWSER_SCREENSHOT_DIR": "/path/to/your/browser-agent/screenshots"
      }
    }
  }
}

3. Alternative Configurations

GitHub Repository - Headless Mode: ``json { "mcpServers": { "browser-agent": { "command": "uv", "args": [ "run", "--from", "git+https://github.com/galilio/browser-mcp.git", "python", "start.py", "--headless" ], "env": { "BROWSER_ENGINE": "playwright" } } } } ``

GitHub Repository - Selenium Engine: ``json { "mcpServers": { "browser-agent": { "command": "uv", "args": [ "run", "--from", "git+https://github.com/galilio/browser-mcp.git", "python", "start.py", "--engine", "selenium" ], "env": { "BROWSER_HEADLESS": "false" } } } } ``

4. Restart Claude Desktop

After adding the configuration, restart Claude Desktop for the changes to take effect.

Usage Examples

Once configured, you can use the browser agent in Claude Desktop:

• "Navigate to https://example.com"
• "Take a screenshot of the page"
• "Click the login button"
• "Type 'hello world' in the search box"
• "Extract all links from the page"
• "Scroll down to the bottom"
• "Fill out a contact form with my information"

Running the MCP Server

Direct Execution

# Basic startup
uv run python start.py

# Headless mode
uv run python start.py --headless

# Using Selenium engine
uv run python start.py --engine selenium

# Custom timeout
uv run python start.py --timeout 60000

# Custom screenshot directory
uv run python start.py --screenshot-dir ./my_screenshots

Environment Variables

Create a .env file based on env.example:

# Browser Configuration
BROWSER_ENGINE=playwright
BROWSER_HEADLESS=false
BROWSER_TIMEOUT=30000
BROWSER_SCREENSHOT_DIR=./screenshots
BROWSER_USER_AGENT=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36
BROWSER_ARGS=--no-sandbox,--disable-dev-shm-usage

# MCP Configuration
MCP_SERVER_NAME=browser-agent

Available Tools

The MCP server provides the following tools:

• navigate_to: Navigate to a URL
• click_element: Click on an element
• type_text: Type text into an element
• get_page_content: Get page content (text or HTML)
• take_screenshot: Take a screenshot
• wait_for_element: Wait for an element to appear
• execute_javascript: Execute JavaScript code
• scroll_page: Scroll the page
• get_elements: Get elements by selector

Troubleshooting

If the server doesn't start:

• Make sure Python 3.10+ is installed
• Verify that uv sync and uv run playwright install completed successfully
• Check that the start.py file is in the correct directory
• Try running uv run python start.py --check-only to verify the environment
• Ensure uv is installed and available in your PATH
• Verify the absolute path in your MCP configuration is correct

For other MCP clients

GitHub Repository Configuration: ``json { "mcpServers": { "browser-agent": { "command": "uv", "args": [ "run", "--from", "git+https://github.com/galilio/browser-mcp.git", "python", "start.py" ], "env": { "BROWSER_ENGINE": "playwright", "BROWSER_HEADLESS": "false" } } } } ``
