This MCP server provides a fast, efficient way to capture web page screenshots optimized for AI vision workflows. It automatically tiles full pages into 1072x1072 chunks for optimal processing by Claude Vision API and other AI models.

Installation

Claude Code

claude mcp add screenshot-website-fast -s user -- npx -y @just-every/mcp-screenshot-website-fast

VS Code

code --add-mcp '{"name":"screenshot-website-fast","command":"npx","args":["-y","@just-every/mcp-screenshot-website-fast"]}'

Cursor

    }
  }
}

Prerequisites

  • Node.js 20.x or higher
  • npm or npx
  • Chrome/Chromium (automatically downloaded by Puppeteer)

Using the Screenshot Tool

Available Tools

take_screenshot

Captures a high-quality screenshot of a webpage.

Parameters:

  • url (required): The HTTP/HTTPS URL to capture
  • width (optional): Viewport width in pixels (max 1072, default: 1072)
  • height (optional): Viewport height in pixels (max 1072, default: 1072)
  • fullPage (optional): Capture full page screenshot with tiling (default: true)
  • waitUntil (optional): Wait until event: load, domcontentloaded, networkidle0, networkidle2 (default: domcontentloaded)
  • waitFor (optional): Additional wait time in milliseconds
  • directory (optional): Directory to save screenshots - returns file paths instead of base64 images

Examples:

Basic usage (returns base64 images):

take_screenshot(url="https://example.com")

Save to directory (returns file paths):

take_screenshot(url="https://example.com", directory="/path/to/screenshots")

Taking Screencasts

take_screencast

Captures a series of screenshots over time to create a screencast.

Parameters:

  • url (required): The URL to capture
  • duration (optional): Total duration in seconds (default: 10)
  • interval (optional): Interval between screenshots in seconds (default: 2)
  • jsEvaluate (optional): JavaScript code to execute at the start
  • waitUntil (optional): Wait strategy: 'load', 'domcontentloaded', 'networkidle0', 'networkidle2'
  • waitForMS (optional): Additional wait time before starting
  • directory (optional): Save as animated WebP to directory (captures every 1 second)

Examples:

Basic screencast (5 frames over 10 seconds):

take_screencast(url="https://example.com")

Custom timing:

take_screencast(url="https://example.com", duration=15, interval=3)

With JavaScript execution:

take_screencast(
  url="https://example.com",
  jsEvaluate="document.body.style.backgroundColor = 'red';"
)

Save as animated WebP:

take_screencast(url="https://example.com", directory="/path/to/output")

CLI Usage

You can also use this tool directly from the command line:

# Full page with automatic tiling (default)
npm run dev capture https://example.com -o screenshot.png

# Viewport-only screenshot  
npm run dev capture https://example.com --no-full-page -o screenshot.png

# Wait for specific conditions
npm run dev capture https://example.com --wait-until networkidle0 --wait-for 2000 -o screenshot.png

CLI Options

  • -w, --width <pixels> - Viewport width (max 1072, default: 1072)
  • -h, --height <pixels> - Viewport height (max 1072, default: 1072)
  • --no-full-page - Disable full page capture and tiling
  • --wait-until <event> - Wait until event: load, domcontentloaded, networkidle0, networkidle2
  • --wait-for <ms> - Additional wait time in milliseconds
  • -o, --output <path> - Output file path (required for tiled output)

Troubleshooting

Puppeteer Issues

  • Ensure Chrome/Chromium can be downloaded
  • Check firewall settings
  • Try setting PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true and provide custom executable

Screenshot Quality

  • Adjust viewport dimensions
  • Use appropriate wait strategies
  • Check if site requires authentication

Timeout Errors

  • Increase wait time with --wait-for flag
  • Use different --wait-until strategies
  • Check if site is accessible

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "screenshot-website-fast" '{"command":"npx","args":["-y","@just-every/mcp-screenshot-website-fast"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "screenshot-website-fast": {
            "command": "npx",
            "args": [
                "-y",
                "@just-every/mcp-screenshot-website-fast"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
  • Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "screenshot-website-fast": {
            "command": "npx",
            "args": [
                "-y",
                "@just-every/mcp-screenshot-website-fast"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
