Overview

What is MCP Browser Automation?

MCP Browser Automation is an open-source MCP (Model Context Protocol) server that provides browser automation capabilities to external AI systems. It exposes a set of browser control tools through the MCP protocol, enabling AI assistants to navigate websites, interact with DOM elements, and extract web content programmatically.
