WHAT IT DOES

What control_create does on Godot Breakpoint

AI agents use control_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.

RISK

Why control_create is rated Medium

The tool creates new UI nodes in the Godot scene tree, which modifies the scene state reversibly (described as 'undoable'). This is a Write operation—it adds data structures to the scene but does not execute arbitrary code, delete data, or cause destructive side effects. The undo support confirms reversibility.

RECOMMENDED RULE

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

control_create Rate-limited

control_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 control_create call is checked against it from then on.

Can I rate-limit control_create? +

Yes. Add a rate_limit block to the control_create rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
