Universal Screenshot MCP

An MCP (Model Context Protocol) server that provides AI assistants with screenshot capabilities — both web page capture via Puppeteer and cross-platform system screenshots using native OS tools.

Features

• Web Page Screenshots — Capture any public URL using a headless Chromium browser
• Cross-Platform System Screenshots — Fullscreen, window, or region capture using native OS tools (macOS screencapture, Linux maim/scrot/gnome-screenshot/etc., Windows PowerShell+.NET)
• Security-First Design — SSRF prevention, path traversal protection, DNS rebinding defense, command injection prevention, and DoS limiting
• MCP Native — Integrates directly with Claude Desktop, Cursor, and any MCP-compatible client

Requirements

• Node.js >= 18.0.0
• Chromium is downloaded automatically by Puppeteer on first run

Platform-Specific Requirements for take_system_screenshot

Linux Installation Examples

# Ubuntu/Debian (recommended)
sudo apt install maim xdotool

# Fedora
sudo dnf install maim xdotool

# Arch Linux
sudo pacman -S maim xdotool

# Wayland (Sway, etc.)
sudo apt install grim

After installing, you can verify your setup with:

npx universal-screenshot-mcp --doctor

This probes the host and prints copy-pasteable install commands for any missing tools, tailored to your detected distro.

Quick Start

Install from npm

npm install -g universal-screenshot-mcp

Or run directly with npx:

npx universal-screenshot-mcp

Install from Source

git clone https://github.com/sethbang/mcp-screenshot-server.git
cd mcp-screenshot-server
npm install
npm run build

Configure Your MCP Client

Add the server to your MCP client configuration. For Claude Desktop, edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "screenshot-server": {
      "command": "npx",
      "args": ["-y", "universal-screenshot-mcp"]
    }
  }
}

Or if installed from source:

{
  "mcpServers": {
    "screenshot-server": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-screenshot-server/build/index.js"]
    }
  }
}

For Claude Code, register the server with the claude mcp add command:

# Project scope (current directory only)
claude mcp add screenshot-server -- npx -y universal-screenshot-mcp

# User scope (available across all projects)
claude mcp add --scope user screenshot-server -- npx -y universal-screenshot-mcp

Or if installed from source:

claude mcp add screenshot-server -- node /absolute/path/to/mcp-screenshot-server/build/index.js

Verify the server registered with claude mcp list, or check live status from inside a session with /mcp.

For Cursor or other MCP clients, consult their documentation for the equivalent configuration.

Tools

The server exposes two MCP tools:

take_screenshot

Captures a web page (or a specific element) via a headless Puppeteer browser.
