What control_set_size_flags does on Godot Breakpoint
AI agents use control_set_size_flags 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 control_set_size_flags is rated Medium
This tool modifies Control node properties (size flags) without deleting data or executing arbitrary code. It falls under Write as it creates or modifies data reversibly. Severity is medium because misuse could break UI layouts or prevent proper rendering, but the effect is confined to a single node's properties and is easily undoable through the editor or script.
From the tool's definition 'Set a Control' indicates modification of Control node properties (size_flags), which alters the state of a UI element in the Godot scene. This is a reversible change to node metadata.
Attacks that exploit this kind of access
The rule that runs control_set_size_flags 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_set_size_flags, this is the rule to start with:
control_set_size_flags 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_set_size_flags call is checked against it from then on.
Questions about control_set_size_flags
Set a Control. It is categorised as a Write tool in the Godot Breakpoint MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Godot Breakpoint MCP server in PolicyLayer and add a rule for control_set_size_flags: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Godot Breakpoint. Nothing to install.
control_set_size_flags is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the control_set_size_flags 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.
Set action: deny in the PolicyLayer policy for control_set_size_flags. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
control_set_size_flags is provided by the Godot Breakpoint MCP server (jlivingston-Cipher/godot-breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
