WHAT IT DOES

What scene_new does on Godot Breakpoint

AI agents use scene_new 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_new is rated Medium

This tool creates and saves a new scene file. Although the description uses the word 'DESTRUCTIVE', the action is creating/writing a new file rather than deleting or irreversibly overwriting existing data. It is gated by confirmation, reducing risk. The primary effect is a reversible file write (the file can be deleted afterward). Severity is medium due to potential to overwrite an existing file at the given path.

From the tool's definition Create a new scene with the given root class, save it to a path, and open it. DESTRUCTIVE (writes a file) — gated by confirmation.

RECOMMENDED RULE

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

scene_new Rate-limited

scene_new 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.
