Jshook MCP Server

@jshookmcp/jshook

English | 中文

An MCP server that gives AI agents 402 tools across 36 domains for JavaScript analysis and security research — browser automation, CDP debugging, network interception, JS hooks, LLM-powered code analysis, process/memory forensics, WASM reverse engineering, source-map reconstruction, AST transforms, and composite workflows in a single server.

🚀 Quick Start

No global install needed — add to your MCP client config and you're ready:

Claude Desktop / Cursor (claude_desktop_config.json):

{
  "mcpServers": {
    "jshook": {
      "command": "npx",
      "args": ["-y", "@jshookmcp/jshook@latest"],
      "env": { "JSHOOK_BASE_PROFILE": "search" }
    }
  }
}

(Windows: use npx.cmd absolute path if npx is not found)

🌟 Highlights

• 🤖 AI-Driven Analysis — LLM-powered deobfuscation, crypto detection, AST comprehension
• ⚡ Search-First Context Efficiency — search profile ≈ 3K tokens vs full ≈ 40K+ tokens
• 🎯 Progressive Tiers — search → workflow → full, activate on demand
• 🌐 Full-Stack Browser Automation — Chromium/Camoufox + CDP + anti-detection + CAPTCHA handling
• 🔁 Runtime Recovery and Session Isolation — HTTP sessions restore activated domains, browser attach state, coverage state, and isolate browser-side session state per client
• 🧭 Schema-First Meta Tools — describe_tool, validated call_tool, and coverage_report reduce parameter errors and make tool coverage visible
• 📡 Network Interception — HTTP/2 frame building, MiTM capture, GraphQL, Burp Suite bridge
• 🛠️ Reverse Engineering Toolchain — WASM disassembly, binary analysis, Frida, Ghidra/IDA bridges
• 🧰 Process & Memory Forensics — Native FFI scanning, hardware breakpoints, PE introspection
• 🧩 Dynamic Extensibility — Hot-reload plugins, declarative workflows, auto-discovered domains

Recent Runtime Notes

• HTTP transport now multiplexes independent MCP sessions and restores runtime state after reconnects.
• proxy_start auto-generates a local HTTPS interception CA when needed.
• Browser CAPTCHA solving is now explicit-input driven: pass taskKind, siteKey, imageBase64, callbackName, and responseSelector as needed. Built-in widget/page signature probing is intentionally not used.

Architecture

• Runtime Registry — Domains auto-discovered via manifest.ts; add a domain by creating one file
• Lazy Initialization — Handlers instantiated on first call, not at startup
• BM25 + Vector Search — search_tools meta-tool with hybrid ranking and adaptive weights
• MCP ToolAnnotations — Every tool carries readOnlyHint / destructiveHint / idempotentHint / openWorldHint
