WHAT IT DOES

What whitelist_manage does on Minecraft Server MCP

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

WHY IT NEEDS A POLICY

Why whitelist_manage needs a policy

Whitelist management allows adding or removing players from access control lists, which modifies server state reversibly. Players can be re-added to the whitelist if removed. While this affects server access and player experience, it is not destructive (data loss), financial, or code execution.

From the tool's definition Tool name 'whitelist_manage' and description 'Manage the server whitelist' indicates creation and modification of whitelist entries. Sibling tools like 'ban_player', 'deop_player', and 'execute_command' confirm this is an administrative modification tool.
