DevTool MCP

DevTool MCP is an open-source Model Context Protocol (MCP) server aimed at developers working with AI coding agents such as Claude Code, Cursor, and other MCP-compatible clients. It exposes a suite of browser instrumentation, process management, reverse proxy, project detection, tunneling for device testing, and frontend diagnostics tools, all accessible by AI assistants to greatly enhance real-time development workflows. DevTool MCP integrates deeply with browsers and terminals to empower agents with environment awareness—enabling capabilities like visual debugging, wireframing, real-time error reporting, direct browser-to-agent messaging, process execution and management, structured context sharing, and more.
