What scene_create does on Godot
AI agents use scene_create to create or update resources in Godot, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot environment.
Why scene_create is rated Medium
This tool creates new scene files, which is a reversible write operation. It modifies the project by adding new scenes but does not execute arbitrary code, delete data irreversibly, or move financial resources. The severity is medium rather than low because uncontrolled scene creation could clutter projects or consume resources, but the operation is reversible through deletion.
From the tool's definition Tool name 'scene_create' and description 'Create a new Godot scene file' directly indicate creation of new data/files within the Godot project.
Attacks that exploit this kind of access
The rule that runs scene_create safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For scene_create, this is the rule to start with:
scene_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, apply this rule, and every scene_create call is checked against it from then on.
Questions about scene_create
Create a new Godot scene file. It is categorised as a Write tool in the Godot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Godot MCP server in PolicyLayer and add a rule for scene_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. Nothing to install.
scene_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 scene_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 scene_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.
scene_create is provided by the Godot MCP server (chanceflow/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
