# Shadow-CLJS Build Monitor

> Use this tool when you need to monitor ClojureScript builds in real-time and track build progress, providing detailed status information and metrics on compilation, warnings, errors, and file-specific details. It solves problems of build verification and debugging for AI assistants working with ClojureScript codebases. The tool takes a running shadow-cljs instance as input and outputs comprehensive build metrics via a WebSocket connection.

## Description

Shadow-cljs-mcp is a Model Context Protocol server that monitors ClojureScript builds in real-time, providing AI assistants with detailed build status information. Developed by Bill Hedworth, this Node.js implementation connects to a running shadow-cljs instance via WebSocket, tracks build progress, and exposes a tool that returns comprehensive build metrics including compilation status, warnings, errors, and file-specific details. It's particularly valuable for AI assistants working with ClojureScript codebases who need to verify build success after making code changes.
