execute_command_structured · LuzzyTool MCP: Risk & Policy

WHAT IT DOES

What execute_command_structured does on LuzzyTool

AI agents invoke execute_command_structured to trigger actions in LuzzyTool. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why execute_command_structured needs a policy

This tool executes arbitrary shell commands, which can trigger external operations with effects dependent on the command arguments. Shell execution is a classic Execute category risk—an AI agent could run destructive, financial, or malicious commands. The structured JSON parsing aspect does not change the fundamental nature of shell execution.

From the tool's definition Tool name contains 'execute_command' and description states '执行 shell 命令' (execute shell commands). This explicitly performs shell command execution with structured output parsing.
