Create a high-level block-based gameplay prototype scaffold in a Godot project
AI agents use create_gameplay_prototype to create or update resources in Godot Devtool — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot Devtool environment.
This tool creates new project content (prototype scaffolds) but does not execute arbitrary code, delete data, or cause irreversible changes beyond what can be undone via version control or project revert. The blast radius is moderate because a mistaken prototype scaffold could bloat the project structure, but it remains reversible.
From the tool's definition Tool name includes 'create', and description states 'Create a high-level block-based gameplay prototype scaffold' — indicates generation and addition of new game assets/code structures to the Godot project.
Documented attack patterns abuse exactly the kind of access create_gameplay_prototype gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Godot Devtool, and nothing reaches the server without passing your rules. This is the rule we recommend for create_gameplay_prototype:
{
"version": "1",
"default": "deny",
"tools": {
"create_gameplay_prototype": {
"limits": [
{
"counter": "create_gameplay_prototype_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_gameplay_prototype 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 high-level block-based gameplay prototype scaffold in a Godot project. It is categorised as a Write tool in the Godot Devtool MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Godot Devtool MCP server in PolicyLayer and add a rule for create_gameplay_prototype: 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 Devtool. Nothing to install.
create_gameplay_prototype 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_gameplay_prototype 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_gameplay_prototype. 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_gameplay_prototype is provided by the Godot Devtool MCP server (wangdiandao/godot-devtool). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
