execute_tool · Korean Stat MCP: Risk & Policy

WHAT IT DOES

What execute_tool does on Korean Stat

AI agents invoke execute_tool to trigger actions in Korean Stat. 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_tool needs a policy

This tool allows arbitrary execution of other registered tools on the server by name, without direct constraints visible in this interface. While the underlying tools (aggregate_statistics, browse_categories, etc.) are primarily Read operations, the ability to dynamically invoke any of them in sequence or with uncontrolled parameters makes this an Execute category tool.

From the tool's definition Tool name 'execute_tool' combined with description stating it calls 'arbitrary registered tools' (임의의 등록된 도구를 호출) as an 'escape hatch' (escape hatch). This is a meta-invocation capability.
