What is the difference between Docker and NPX usage?
The Docker implementation runs headless Chromium, while the NPX version opens a visible browser window.

Puppeteer is an MCP server that provides browser automation capabilities using Puppeteer, enabling LLMs to interact with web pages, take screenshots, and execute JavaScript in a real browser environment.
You can run Puppeteer via Docker (using headless Chromium) or via NPX. Configure it in your MCP client (e.g., Claude Desktop) with the command and arguments provided in the README.
The Docker implementation runs headless Chromium, while the NPX version opens a visible browser window.
It provides access to console logs via `console://logs` and screenshots via `screenshot://<name>` as PNG images.
You need either Docker or Node.js with NPX installed, along with a compatible MCP client (e.g., Claude Desktop).
Screenshots are stored in memory and accessible via the name specified during capture using the resource URI `screenshot://<name>`.
Yes, when using Docker the browser runs headless, so no display server is required.
