PWA Debug Layer

Overview

PWA Debug Layer is a Model Context Protocol server that lets you debug progressive web applications directly in your browser. It provides insight into service workers, cache storage, installability checks, and framework state—giving AI assistants like Claude real-time visibility into PWA internals so they can help diagnose and fix issues.

The server runs locally via the npm package @aryanduntley/pwa-debug, installed with npx -y @aryanduntley/pwa-debug. It requires no authentication and works immediately after setup. Version v0.2.0 is available under the MIT license, with full source code at aryanduntley/pwa-debug-layer on GitHub.

PWA Debug Layer belongs in the Development category on mcp.site and integrates with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, and others. If you maintain this project, claim your listing to verify ownership and keep the information accurate.
