PHP Debugbar FAQs

Question 1

What is PHP Debugbar and what does it do?

PHP Debugbar (mcp-php-debugbar) connects your existing PHP DebugBar and Laravel Debugbar installations to popular AI assistants. It enables AI-powered debugging by providing concrete, line-numbered code fix suggestions directly within your AI tool for common PHP and Laravel issues.

Question 2

What specific types of issues can PHP Debugbar detect?

PHP Debugbar is designed to detect and help fix critical PHP and Laravel application issues such as N+1 database query problems, slow-running queries, and uncaught exceptions. It analyzes application behavior to pinpoint the exact location and suggest a resolution.

Question 3

How does PHP Debugbar provide AI-powered code fixes?

Accepted Answer

It integrates with your AI assistant via the Model Context Protocol (MCP). The AI receives detailed runtime data (exceptions, SQL queries, timelines, logs) from your running application. It then reads your PHP source files, analyzes detected issues, and suggests precise, line-numbered code fixes that you can apply directly.

PHP Debugbar currently supports a range of leading AI clients, including Cursor, VS Code (with the GitHub Copilot Chat extension), Claude Desktop, and OpenAI Codex. Full native integration for Antigravity is also actively under development.

Accepted Answer

To use PHP Debugbar, you need Node.js 18+, PHP 7.4+ (running a dev server for your app), and either PHP DebugBar v3.5+ or Laravel Debugbar v4.1+ installed in your project. Setup involves configuring the MCP server within your chosen AI client.
