clone_room · Loenn MCP: Risk & Policy

WHAT IT DOES

What clone_room does on Loenn

AI agents use clone_room to create or update resources in Loenn — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Loenn environment.

WHY IT NEEDS A POLICY

Why clone_room needs a policy

Based on the tool name 'clone_room' and the server context (editing Celeste .bin map files), this tool likely duplicates/copies an existing room into the map, which is a Write operation (creates new data reversibly). The sibling tools like 'add_room', 'add_entity' confirm a pattern of write operations. Confidence is lowered due to the empty description.

From the tool's definition Tool name 'clone_room'; description is empty and uninformative.
