js-reverse-mcp-debugging

Skill by ara.so — MCP Skills collection.

Overview

js-reverse-mcp is an MCP server that gives AI agents full JavaScript debugging capabilities: breakpoints, call stacks, scope inspection, network analysis, and WebSocket message capture. Built on Patchright (CDP protocol anti-detection) with optional CloakBrowser (49 C++ fingerprint patches) for strong anti-bot sites.

Key features:

• Headful debugging — visible browser, breakpoints, step-through, call stacks
• Persistent sessions — cookies/localStorage survive restarts
• Dual anti-detection — Patchright (protocol layer) + optional CloakBrowser (binary patches)
• 21 MCP tools — script analysis, breakpoint control, network inspection, WebSocket analysis
• Zero JS injection — no Object.defineProperty hacks that leak automation signals
