What light_create does on Godot Breakpoint
AI agents use light_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 light_create is rated Medium
This tool creates a new 3D light node in the Godot scene graph as a child of a specified parent. Creation of scene objects is a Write-category operation because it modifies the scene state reversibly (can be undone). While it affects the scene structure, it does not execute arbitrary code, delete data, or trigger external operations.
From the tool's definition The tool description states 'Add a 3D light under a parent (undoable)' - indicating it creates a new scene object. The '(undoable)' note confirms this is a reversible modification operation rather than a destructive action.
Attacks that exploit this kind of access
The rule that runs light_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 light_create, this is the rule to start with:
light_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 light_create call is checked against it from then on.
Questions about light_create
Add a 3D light under a parent (undoable). 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 light_create: 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.
light_create 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 light_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.
Set action: deny in the PolicyLayer policy for light_create. 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.
light_create 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.
