Why scene_save_as is rated Medium
This tool writes a file to a new path, which is a Write operation. While the description labels it 'DESTRUCTIVE', saving to a new path does not irreversibly delete or overwrite existing data — it creates or writes a new file. The severity is high because it can overwrite files at arbitrary res:// paths, potentially corrupting project assets, but it is gated by confirmation.

The rule that runs scene_save_as safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For scene_save_as, this is the rule to start with:
scene_save_as 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Breakpoint, apply this rule, and every scene_save_as call is checked against it from then on.
