Create a new Godot scene file
AI agents use create_scene to create or update resources in Godot MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot MCP environment.
The tool creates a new scene file in a Godot project, which is a Write operation (data creation/modification). Severity is medium because while scene files can be deleted if created by mistake, creating scenes is a normal part of development workflow and the impact is limited to the Godot project workspace. The operation is reversible and does not trigger Financial, Destructive, or Execute-class risks.
From the tool's definition Tool description states 'Create a new Godot scene file' — this is a reversible creation operation that writes data to the file system without permanently destroying existing data.
Documented attack patterns abuse exactly the kind of access create_scene gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Godot MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for create_scene:
{
"version": "1",
"default": "deny",
"tools": {
"create_scene": {
"limits": [
{
"counter": "create_scene_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_scene 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.

Create a new Godot scene file. It is categorised as a Write tool in the Godot MCP 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 create_scene: 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 MCP. Nothing to install.
create_scene 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 create_scene 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 create_scene. 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.
create_scene is provided by the Godot MCP server (leesinliang/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Godot MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
