Console Catcher

Captures browser console errors for AI coding assistants like Claude Code

Console Catcher silently captures browser console errors and makes them available to AI coding assistants like Claude Code, Cursor, and other MCP-compatible tools. The problem: You push code, test in the browser, something breaks. You open DevTools, find the error, copy the stack trace, paste it into your AI coding tool, and explain what happened. Multiple times a day. Console Catcher eliminates this friction. Errors flow automatically from your browser to your AI assistant. How it works: 1. Install the MCP server: npm install -g console-catcher 2. Install this Chrome extension 3. Code normally. When something breaks, your AI already has the error. What it captures: - console.error() calls - Uncaught exceptions - Unhandled promise rejections Each error includes the full stack trace, source URL, line/column numbers, and timestamp. MCP Tools available to your AI: - get_errors: Retrieve captured errors with URL and time filtering - clear_errors: Clear captured errors - get_error_stats: Quick summary of error counts by domain Open source: https://github.com/lewismcgui/console-catcher
