Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

[](https://www.npmjs.com/package/universal-screenshot-mcp) [](https://registry.modelcontextprotocol.io) [](LICENSE)

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

Questions

What is the Screenshot MCP server?

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

What tools does Screenshot expose?

2 in total: 2 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Screenshot safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Screenshot need?

No credential environment variables were found in its source, so it appears to need none.

How does Screenshot run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as universal-screenshot-mcp at 1.4.0.

How current is this page?

The grade is for one exact copy of the source (8364a81f3bbc), read on 2026-10-08. The repository is watched and re-audited when it changes.
