What resource_duplicate does on Godot Breakpoint
AI agents use resource_duplicate to create or update resources in Godot Breakpoint, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot Breakpoint environment.
Why resource_duplicate is rated Medium
Although the description says 'DESTRUCTIVE (writes a file)', the actual operation is creating/writing a duplicate to a new path, not deleting or overwriting irreplaceable data. File creation/copying is reversible (the new file can be deleted). The confirmation gate further mitigates risk. This is Write rather than Destructive because no existing data is lost; the operation is reversible via file deletion.
From the tool's definition The tool "duplicates" a resource and "saves the copy to a new path." It creates new file content (a copy) rather than irreversibly destroying existing data. The description explicitly warns it is gated by confirmation.
Attacks that exploit this kind of access
The rule that runs resource_duplicate safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For resource_duplicate, this is the rule to start with:
resource_duplicate 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 Breakpoint, apply this rule, and every resource_duplicate call is checked against it from then on.
Questions about resource_duplicate
Load a resource, duplicate it (optionally deep, cloning subresources), and save the copy to a new path. DESTRUCTIVE (writes a file) — gated by confirmation. It is categorised as a Write tool in the Godot Breakpoint MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Godot Breakpoint MCP server in PolicyLayer and add a rule for resource_duplicate: 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 Breakpoint. Nothing to install.
resource_duplicate 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_duplicate 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_duplicate. 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_duplicate is provided by the Godot Breakpoint MCP server (jlivingston-Cipher/godot-breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
