What duplicate_resource does on Godot
AI agents use duplicate_resource 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 |
|---|---|---|---|
dest_path | string | Yes | Destination path |
source_path | string | Yes | Source resource path |
Parameters from the server's own tool schema.
Why duplicate_resource is rated Medium
Duplicating a resource is a write operation that creates new data reversibly. It does not execute code, delete data irreversibly, or move money. While it modifies the project state, the action is non-destructive and can be undone. Severity is medium because uncontrolled duplication could consume disk space or clutter the project, but the impact is localized to resource files and reversible.
From the tool's definition Tool name is 'duplicate_resource' and description states 'Duplicate a resource file'. This creates a copy of an existing resource, modifying the filesystem by adding new data.
Risk signalsAccepts file system path (source_path)
Attacks that exploit this kind of access
The rule that runs duplicate_resource 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 duplicate_resource, this is the rule to start with:
duplicate_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.
The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every duplicate_resource call is checked against it from then on.
Questions about duplicate_resource
Duplicate a resource file. 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.
duplicate_resource accepts 2 parameters: dest_path, source_path. Required: dest_path, source_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 duplicate_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. Nothing to install.
duplicate_resource 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 duplicate_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.
Set action: deny in the PolicyLayer policy for duplicate_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.
duplicate_resource is provided by the Godot MCP server (@keeveeg/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
