byob

Overview

byob is a comprehensive MCP server that bridges AI coding tools with your actual Chrome browser. It eliminates the need for headless browsers by allowing AI agents to interact with the same browser session where you're already logged into various services. The project provides extensive browser automation tools through MCP, including navigation, interaction, content extraction, and evaluation capabilities. With proper security measures and zero outbound data transmission, byob operates entirely locally.
