Save text-based Godot resource content with overwrite protection
AI agents use resource_save 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 enables creation or modification of Godot resource files, which are persistent project assets. While the 'overwrite protection' suggests safeguards against accidental overwrites, the fundamental capability is to modify project state irreversibly. It does not delete data (which would be Destructive), but it can corrupt or alter critical game assets.
From the tool's definition Tool name 'resource_save' and description 'Save text-based Godot resource content with overwrite protection' indicate modification of persistent data.
Documented attack patterns abuse exactly the kind of access resource_save 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 resource_save:
{
"version": "1",
"default": "deny",
"tools": {
"resource_save": {
"limits": [
{
"counter": "resource_save_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}resource_save 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.

Save text-based Godot resource content with overwrite protection. 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 resource_save: 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.
resource_save 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 resource_save 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 resource_save. 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.
resource_save 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.
