Kaboom Browser AI Devtools MCP, developed by Brennhill, is an MCP server designed for local-first browser development workflows. Built with Go, it connects to Chrome/Chromium browsers (version 120+) via a browser extension, streaming real-time telemetry to compatible AI coding assistants. This free tool acts as an AI debugger, inspector, and verification toolkit, helping developers understand and improve browser interactions. Its installation involves a single Go binary and a browser extension, offering multiple ways to get started.

What does Kaboom Browser AI Devtools MCP connect to?

Kaboom Browser AI Devtools MCP connects to a Chrome/Chromium browser (version 120+) through a dedicated browser extension. This connection streams real-time browser telemetry directly to AI coding assistants that support the Model Context Protocol (MCP). It operates as an MCP server, serving as an AI debugger, inspector, and verification toolkit. The system is specifically built for local-first browser development workflows, providing detailed analysis of browser behavior and interactions.

Core features and tools

The tool exposes several callable functions, each supporting various sub-modes. These include observe for monitoring browser activity, analyze for deeper inspection, generate for creating content or tests, configure for setting up parameters, and interact for direct engagement with the browser. It supports stdio for initial client connections and an internal HTTP server to proxy MCP JSON-RPC calls, sharing telemetry across multiple connected AI clients efficiently.

Who is it for?

This tool is for developers engaged in local-first browser development workflows and users of AI coding assistants. It also serves vendors creating AI development tools. The system helps with debugging browser issues, automating testing, and analyzing performance across various browser interactions. Compatible AI clients include Claude Code, Cursor, Windsurf, Zed, Claude Desktop, VS Code + Continue, Gemini CLI, OpenCode, and Antigravity. Skip this if you do not use a Chrome/Chromium browser or an MCP-compatible AI coding assistant.

How to get started

No credentials are required. The system is designed to bind to 127.0.0.1 only, and authentication headers are automatically stripped for enterprise safety.

Use cases

• Debugging browser issues by streaming console logs, network failures, and exceptions directly to AI assistants for quick analysis.
• Automated testing and verification, such as generating Playwright tests from real browser sessions and verifying code changes against expected outcomes.
• Performance analysis, including capturing Web Vitals data and automating performance audits to identify areas for improvement.

Kaboom Browser AI Devtools MCP offers a direct link between browser activity and AI coding assistants for local development. Its design prioritizes security by binding to localhost and stripping authentication headers. This free tool provides essential debugging, testing, and performance analysis capabilities for browser-centric projects.
