create_resource · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_resource does on Godot MCP Server

AI agents use create_resource to create or update resources in Godot MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot MCP Server environment.

WHY IT NEEDS A POLICY

Why create_resource needs a policy

This tool creates new resource files (reversible write operation) but does not execute arbitrary code, delete data, or move money. The severity is medium because creating resources could affect game behavior and structure, but the operation is reversible—files can be deleted or modified later. Confidence is high because the intent and mechanism are clearly documented.

From the tool's definition create_resource creates Godot resource files (.tres); the name explicitly includes 'create' and the description confirms it generates new resource artifacts like shapes and materials.

Verdict

create_resource Rate-limited

create_resource 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.

FAQ

Questions about create_resource

What does the create_resource tool do? +

Create a Godot resource file (.tres) like shapes, materials, or other resources. It is categorised as a Write tool in the Godot MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_resource? +

Register the Godot MCP Server MCP server in PolicyLayer and add a rule for create_resource: 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 Server. Nothing to install.

What risk level is create_resource? +

create_resource is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_resource? +

Yes. Add a rate_limit block to the create_resource 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.

How do I block create_resource completely? +

Set action: deny in the PolicyLayer policy for create_resource. 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.

What MCP server provides create_resource? +

create_resource is provided by the Godot MCP Server MCP server (koltyakov/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
