jshookmcp — Claude Code MCP server for JS analysis
Give an agent tools to inspect JavaScript apps, capture browser traffic, analyze WASM modules, and work with live processes.
claude mcp add jshookmcp -- npx -y @jshookmcp/jshookWhat jshookmcp does
jshookmcp provides tools for JavaScript reverse engineering and browser analysis. It can automate Chromium and Camoufox, capture HTTP and WebSocket traffic, and assist with GraphQL and source maps. The search profile helps locate tools; workflow supports composite tasks.
The server also handles WASM disassembly through wabt and bridges to Frida, Ghidra, and IDA. Its process and memory tools support live inspection, while its Android tooling covers APK analysis. Running it through npx requires Node.js 22.22.2 or later, so check your Node.js version before setup.
What it helps with
- capture a page’s HTTP and WebSocket traffic
- locate cryptographic routines in JavaScript
- disassemble a WASM module and inspect its functions
- attach to a browser and examine its targets
- inspect APK manifests and DEX code
Example prompts for the agent
- Inspect this page’s JavaScript and find its cryptographic routines.
- Capture this page’s network traffic and examine its WebSocket messages.
- Disassemble this WASM module and list its functions and strings.
