# DevServer Monitor

> Use this tool when you need to streamline debugging workflows for development server processes, such as Vite or npm run dev, and automate error analysis with intelligent categorization and file change correlation. It solves problems like manual console output parsing and error tracking, providing inputs like configurable regex patterns and outputs like structured error categories with severity levels. Ideal for developers working with modern JavaScript frameworks, it enables efficient identification of error causes, tracking of error patterns, and summary analysis of development server issues.

## Description

This MCP server monitors development server processes (Vite, npm run dev, etc.) and provides intelligent error categorization and file change correlation for debugging workflows. Built by Tristan Brotherton with TypeScript and the MCP SDK, it uses configurable regex patterns to parse and classify errors from TypeScript, Svelte, build tools, and runtime sources into structured categories with severity levels. The implementation features file watching with chokidar to correlate errors with recent code changes, shared state management for persistence across sessions, and comprehensive error tracking with history limits and filtering capabilities. Designed for developers working with modern JavaScript frameworks who need automated error analysis and debugging assistance, it enables use cases like identifying which file changes caused specific errors, tracking error patterns over time, and getting structured summaries of development server issues without manually parsing console output.
