Detects a potential OS command injection attack targeting AutoGen Studio. The rule correlates a suspicious WebSocket connection to the Model Context Protocol (MCP) endpoint on localhost:8081, specifically containing the 'server_params' parameter, with a subsequent shell process spawning from an AutoGen Studio, Python, or Uvicorn parent process. The shell command line includes common injection characters (e.g., ;, |, &&, ||) and OS enumeration commands (e.g., whoami, id, net user).
