Browser

A Model Context Protocol (MCP) server for browser automation using Puppeteer. This enables AI assistants like Claude, GPT, and other LLM-powered tools to navigate web pages, take screenshots, click elements, fill forms, and interact with web content.

Features

• Navigation: Navigate to URLs, go back/forward, reload pages
• Screenshots: Capture full-page or viewport screenshots
• Interaction: Click, type, hover, scroll, select dropdown options
• Content Extraction: Get page content, titles, and links
• JavaScript Execution: Run custom scripts in the browser context
• Wait Conditions: Wait for elements or timeouts

Installation

Prerequisites

• Node.js 18+ (LTS recommended)
• npm, pnpm, or bun

Install via npx (Recommended)

You can run the server directly without installation:

npx github:blink-new/browser-mcp

Install Globally

npm install -g github:blink-new/browser-mcp

Install from Source

git clone https://github.com/blink-new/browser-mcp.git
cd browser-mcp
npm install
npm run build

    }
  }
}

User: Go to example.com and take a screenshot
AI: [Uses browser_navigate with url="https://example.com"]
AI: [Uses browser_screenshot]

Fill a Form

User: Fill out the contact form on the page
AI: [Uses browser_type with selector="#name" text="John Doe"]
AI: [Uses browser_type with selector="#email" text="[email protected]"]
AI: [Uses browser_click with selector="#submit"]

User: Get all the links from this page
AI: [Uses browser_links]

Troubleshooting

Linux: Browser fails to launch

If you see errors about missing libraries, install the Chromium dependencies:

sudo apt-get install -y libnss3 libatk1.0-0 libatk-bridge2.0-0 libcups2 libdrm2 libxkbcommon0 libxcomposite1 libxdamage1 libxfixes3 libxrandr2 libgbm1 libasound2

Docker/Root: Sandbox errors

Use the --no-sandbox flag:

BROWSER_MCP_NO_SANDBOX=true npx github:blink-new/browser-mcp

Or in your config:

{
  "environment": {
    "BROWSER_MCP_NO_SANDBOX": "true"
  }
}

macOS: Puppeteer can't find Chrome

The bundled Chromium should work automatically. If not, specify the path:

BROWSER_MCP_EXECUTABLE_PATH="/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" npx github:blink-new/browser-mcp

Windows: Long path errors

Run PowerShell as Administrator and enable long paths:

New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem" -Name "LongPathsEnabled" -Value 1 -PropertyType DWORD -Force
