Jshookmcp

An MCP server that gives AI agents 600+ tools across 34 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. It runs locally over stdio via the published package.

People connecting browser automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

before you install - you'll need

MCP_TOOL_PROFILE

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add vmoranv-jshookmcp -- npx -y @jshookmcp/jshook

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "vmoranv-jshookmcp": {
      "command": "npx",
      "args": [
        "-y",
        "@jshookmcp/jshook"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
