Description

This MCP exposes tools to take full-page or element-specific screenshots in PNG/JPEG/WebP, return images as base64, and support authenticated workflows via manual login and cookie persistence. It can launch Puppeteer's Chromium or connect to the system default browser (visible) for manual interaction and session reuse. Features include configurable viewport, image quality, wait/delay options, and saved cookies for multi-step workflows, making it useful for agents that need visual verification of web apps.
