DevTool MCP

DevTool MCP (via the agnt tool) is a Model Context Protocol (MCP) server designed to extend the capabilities of AI coding agents like Claude Code and Cursor by providing a real-time, bidirectional integration with the browser. It enables agents to 'see' the browser (screenshots, DOM inspection), receive user feedback, capture errors and network activity, sketch directly on running apps, and streamline debugging and real-time interaction—all in structured, token-efficient formats. It's geared toward developers, researchers, and anyone wanting to supercharge their AI coding assistant with live contextual browser data.
