What theme_create does on Godot Breakpoint
AI agents use theme_create 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.
Why theme_create is rated Medium

Writing a new file is reversible (the file can be deleted afterward). The confirmation gate further reduces severity by ensuring the user must approve the action.
From the tool's definition The tool 'theme_create' is described as creating 'a new empty Theme resource and save it to a res:// path' and explicitly noted as '(writes a file)'.
Attacks that exploit this kind of access
The rule that runs theme_create 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 theme_create, this is the rule to start with:
theme_create 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 Godot Breakpoint, apply this rule, and every theme_create call is checked against it from then on.
