> Use this tool when you need to automate browser interactions or leverage Chrome's functionality within AI workflows, solving problems such as automating web data extraction or simulating user interactions. It takes JavaScript functions as input and outputs the results of their execution within an authenticated browser session. Use it when you require programmatic access to web pages with full DOM and cookie access.

## Description

Bridges AI coding agents to Chrome browser functionality through a WebSocket connection between an MCP server and Chrome extension. Users define custom JavaScript functions that run inside authenticated browser sessions, exposed as callable MCP tools. The server communicates via stdio with the agent and via WebSocket with the extension, which executes scripts in the page's MAIN world with full DOM and cookie access. Supports dynamic script registration through the extension popup, automatic tab matching by URL pattern, and async execution with 30-second timeouts.
