mine_room · Minecraft Survival MCP Server MCP: Risk & Policy

WHAT IT DOES

What mine_room does on Minecraft Survival MCP Server

AI agents invoke mine_room to trigger actions in Minecraft Survival MCP Server. 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 mine_room needs a policy

This tool executes programmatic commands that alter game world state through block removal. While block mining in Minecraft is reversible (blocks can be replaced), the tool itself performs autonomous execute-class actions - it runs code to remove blocks across a defined area rather than merely reading or writing data.

From the tool's definition Tool performs 'mine all blocks in a rectangular area' - this executes autonomous mining operations that modify the game world state by removing blocks based on specified coordinates.
