What makes jshook different

Most MCP servers for JS analysis expose a handful of hand-rolled tools or wrap a single browser engine. jshook is closer to an operating system for front-end reverse engineering — 36 self-discovered domains, a search-first meta-tool that keeps token cost under control, and runtime recovery that survives broken pages and dropped sessions:

• Search-first, profile-aware. The search profile loads about 3K tokens of tool metadata; the full profile exposes all 736 tools at around 109K tokens (measured 2026-10-10 — this figure scales with the tool count, so re-measure it when the catalog grows). Agents move between them as the task grows — search → workflow → full — instead of drowning in schemas from the first turn.
• Runtime recovery and session isolation. Streamable HTTP sessions restore activated domains, browser attach state, and coverage state after reconnects; per-client browser-side state stays isolated so two agents cannot trample each other's CDP sessions.
• Full-stack browser automation. Chromium and Camoufox via CDP with anti-detection, an explicit-input CAPTCHA solver (no built-in page/feature probing), a self-signed HTTPS interception CA on demand, and HTTP/2 frame building.
• Real reverse engineering, not string searches. WASM disassembly via wabt (wasm2wat / wasm-decompile / wasm-objdump), Frida/Ghidra/IDA bridges, native FFI scanning, hardware breakpoints, PE introspection, GraphQL/Burp Suite proxy bridges, and AST transforms — not a single regex call wrapped as a tool.
• Dynamic extensibility. Hot-reload plugins, declarative workflows, and auto-discovery keep the server growing without a redeploy.
