set_map_dependencies · Loenn MCP: Risk & Policy

WHAT IT DOES

What set_map_dependencies does on Loenn

AI agents use set_map_dependencies 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 set_map_dependencies needs a policy

The verb 'set' combined with 'dependencies' suggests creating or modifying map dependency relationships, which is a reversible write operation. This affects map structure but is not destructive (can be undone) or execute-level (doesn't run arbitrary code). Medium severity reflects potential for breaking map functionality if dependencies are misconfigured, but the action is reversible.

From the tool's definition Tool name 'set_map_dependencies' indicates modification of map configuration/metadata. Server description states it enables 'edit' operations on .bin map files. No description provided for this specific tool.
