WHAT IT DOES

What mp_add_synchronizer does on Godot Breakpoint

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

RISK

Why mp_add_synchronizer is rated Medium

This tool creates a new multiplayer synchronizer node in the Godot editor, which modifies the scene tree. The reversibility via undo means it is not destructive. While it affects game state configuration, the blast radius is limited to the current project/scene being edited. Categorized as Write (creates/adds data reversibly) with medium severity due to potential unintended scene modifications if misused by an agent.

From the tool's definition Tool name contains 'add' and description states 'Add a MultiplayerSynchronizer node under a parent'. The '(undoable)' note indicates the action is reversible through undo functionality, confirming this is a write operation rather than destructive.

RECOMMENDED RULE

The rule that runs mp_add_synchronizer safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Godot Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mp_add_synchronizer, this is the rule to start with:

mp_add_synchronizer Rate-limited

mp_add_synchronizer stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
