WHAT IT DOES

What add_break_loop does on RPG Maker MZ MCP Server

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

WHY IT NEEDS A POLICY

Why add_break_loop needs a policy

This tool creates or modifies event command sequences within RPG Maker MZ projects. While it changes game behavior, the modification is reversible (commands can be edited or removed), and it doesn't delete data or execute arbitrary code. It's a Write operation because it adds/modifies game event data structures.

From the tool's definition add_break_loop adds a break loop command to an event, which modifies event logic in RPG Maker MZ projects. The verb 'add' and context of event automation indicates creation/modification of game event structures.
