WHAT IT DOES

What scene_pack does on Godot Breakpoint

AI agents use scene_pack 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 scene_pack is rated Medium

While the tool writes to the filesystem and creates a new file, it does not delete or irreversibly overwrite existing data. Creating a new file is reversible (the file can be deleted). The description's own caution against 'DESTRUCTIVE' behavior and emphasis on confirmation gates suggests the developers considered and mitigated destructive concerns.

From the tool's definition Tool description states 'Save a node branch... as a new PackedScene file' and 'writes a file'. The description acknowledges it is 'gated by confirmation' and explicitly states 'Does not modify the edited scene', indicating the operation is reversible (a new…

RECOMMENDED RULE

The rule that runs scene_pack 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 scene_pack, this is the rule to start with:

scene_pack Rate-limited

scene_pack 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.

How do I block scene_pack completely? +
