What create_world does on Godot
AI agents use create_world 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
path | string | Yes | Output path for World3D .tres (e.g. "environments/main_world.tres") |
environment_path | object | — | Path to Environment .tres to attach |
Parameters from the server's own tool schema.
Why create_world is rated Medium
The tool creates a new World3D resource file, which is a write operation that modifies the project state by adding a new asset. It is reversible (the file can be deleted) and does not execute arbitrary code, delete existing resources irreversibly, or move money.
From the tool's definition Tool name 'create_world' and description 'Create World3D .tres' indicate creation of a new resource file (.tres is Godot's text-serialized resource format). This is a reversible write operation that creates data artifacts in the Godot project.

The rule that runs create_world 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 create_world, this is the rule to start with:
create_world 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 create_world call is checked against it from then on.
Questions about create_world
Create World3D .tres. 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.
create_world accepts 2 parameters: path, environment_path. Required: path. The full parameter table on this page comes from the server's own tool schema.
Register the Godot MCP server in PolicyLayer and add a rule for create_world: 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.
create_world 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_world 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_world. 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_world is provided by the Godot MCP server (@yanhuifair/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
