Frequently asked questions

1

What does this server do?

It provides MCP tools to capture screenshots of web pages (full page, viewport, or specific elements) and return them as base64 encoded images, with support for authentication and session persistence.

2

How does authentication work?

Use the `login-and-wait` tool to manually log in through a visible browser window; cookies are saved automatically and reused in subsequent `screenshot-page` or `screenshot-element` calls when `useSavedAuth` is true.

3

What are the runtime requirements?

Node.js is required. The server uses Puppeteer (bundled Chromium) by default, but can also connect to your system’s default browser (Chrome, Edge, or Safari) with `useDefaultBrowser: true`.

4

What is the difference between headless and visible mode?

Headless mode (`visibleBrowser: false`) is faster for automation; visible mode (`visibleBrowser: true`) shows the browser window, required for `useDefaultBrowser` and manual interactions.

5

Where are authentication cookies stored?

Cookies are saved to the `.mcp-screenshot-cookies` directory in your home folder. They can be cleared per domain or globally using the `clear-auth-cookies` tool.
