Full Analysis
  • [EXTERNAL_DOWNLOADS]: The skill instructs the user to clone source code from an external repository located at https://github.com/NoOne-hub/JSReverser-MCP.git, which is not associated with a known trusted vendor.
  • [REMOTE_CODE_EXECUTION]: The installation instructions require the user to run npm install and npm run build on the downloaded code and then execute the resulting server using node, leading to the execution of untrusted code on the local system.
  • [DATA_EXFILTRATION]: Several tools within the skill, such as dump_session_state, save_session_state, and export_rebuild_bundle, are designed to harvest sensitive browser information, including session cookies and captured network traffic, and save them to local storage.
  • [COMMAND_EXECUTION]: The skill documentation provides instructions to execute shell commands to launch the system's web browser with remote debugging enabled (--remote-debugging-port=9222), which allows the MCP server to programmatically control and inspect the browser environment.
