Questions

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`

Platform	Required Tools	Notes
macOS	`screencapture` (built-in)	No additional installation needed
Linux	One of: `maim`, `scrot`, `gnome-screenshot`, `spectacle`, `grim`, or `import` (ImageMagick)	`maim` or `scrot` recommended for full feature support. For window-by-name capture, also install `xdotool`.
Windows	`powershell` (built-in)	Uses .NET `System.Drawing` — no additional installation needed

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.

Parameter	Type	Required	Description
`url`	string	✅	URL to capture (http/https only)
`width`	number	—	Viewport width (1–3840)
`height`	number	—	Viewport height (1–2160)
`fullPage`	boolean	—	Capture the full scrollable page
`selector`	string	—	CSS selector to capture a specific element
`waitForSelector`	string	—	Wait for this selector before capturing
`waitForTimeout`	number	—	Delay in milliseconds (0–30000)
`outputPath`	string	—	Output file path (default: `~/Documents/screenshots`)

Example prompt:

Take a screenshot of https://example.com at 1920x1080

`take_system_screenshot`

Captures the desktop, a specific application window, or a screen region using native OS tools. Works on macOS, Linux, and Windows.

Parameter	Type	Required	Description
`mode`	enum	✅	`fullscreen`, `window`, or `region`
`windowId`	number	—	Window ID for window mode
`windowName`	string	—	App name (e.g. `"Safari"`, `"Firefox"`) for window mode
`region`	object	—	`{ x, y, width, height }` for region mode
`display`	number	—	Display number for multi-monitor setups
`includeCursor`	boolean	—	Include the mouse cursor in the capture
`format`	enum	—	`png` (default) or `jpg`
`delay`	number	—	Capture delay in seconds (0–10)
`outputPath`	string	—	Output file path (default: `~/Documents/screenshots`)

Cross-Platform Feature Support

Feature	macOS	Linux	Windows
Fullscreen	✅	✅	✅
Region	✅	✅ (maim, scrot, grim, import)	✅
Window by name	✅	⚠️ X11 + xdotool	⚠️ best-effort
Window by ID	✅	✅ X11 only	⚠️ HWND
Multi-display	✅	⚠️ tool-dependent	✅
Include cursor	✅	⚠️ tool-dependent	⚠️
Delay	✅	✅	✅

Example prompt:

Take a system screenshot of the Safari window

Configuration

Environment Variables

Variable	Default	Description
`SCREENSHOT_OUTPUT_DIR`	`Documents/screenshots`	Default output directory relative to `~`
`ALLOW_LOCAL`	`false`	Set to `true` to allow screenshotting `localhost`/`127.x.x.x`/`[::1]` (useful for local dev servers)

Output Directories

Screenshots are saved to ~/Documents/screenshots by default (configurable via SCREENSHOT_OUTPUT_DIR). Custom output paths must resolve to one of these allowed directories:

Directory	Description
`~/Documents/screenshots`	Default output location (configurable)
`~/Desktop/Screenshots`	Original default location
`~/Downloads`	User downloads folder
`~/Documents`	User documents folder
`/tmp`	System temp directory

Security

This server implements multiple layers of security hardening:

ID	Threat	Mitigation
SEC-001	SSRF / DNS rebinding	URLs validated against blocked IP ranges; DNS resolved pre-request with IP pinning via `--host-resolver-rules`; navigation redirects re-validated
SEC-003	Command injection	All subprocesses use `execFile` (no shell); app names validated against `SAFE_APP_NAME_PATTERN`
SEC-004	Path traversal	Output paths validated with `fs.realpath()` symlink resolution; restricted to allowed directories
SEC-005	Denial of service	Concurrent Puppeteer instances limited to 3 via semaphore

For full details, see docs/security.md.

Development

Scripts

Command	Description
`npm run build`	Compile TypeScript to `build/`
`npm run watch`	Recompile on file changes
`npm test`	Unit tests (fast, fully mocked)
`npm run test:integration`	Integration tests (real DNS/filesystem)
`npm run test:e2e`	E2E tests (real Puppeteer/native tools)
`npm run test:all`	All test tiers together
`npm run test:linux`	Linux e2e via Docker (requires Docker)
`npm run test:watch`	Run tests in watch mode
`npm run test:coverage`	Run tests with coverage report
`npm run lint`	Lint source with ESLint
`npm run inspector`	Launch MCP Inspector for debugging

Testing

Tests use Vitest in three tiers:

Unit (npm test) — Full dependency injection, no real I/O. Fast feedback loop.
Integration (npm run test:integration) — Real DNS resolution, real filesystem with temp directories, real Puppeteer against a local HTTP server.
E2E (npm run test:e2e) — Real native screenshot tools. macOS tests run natively; Linux tests run in Docker via npm run test:linux.

npm test                 # Unit tests (~300ms)
npm run test:linux       # Linux provider tests in Docker
npm run test:all         # Everything
