WHAT IT DOES

What duplicate_node does on Cocos

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

RISK

Why duplicate_node is rated Medium

Duplicating a node creates a new copy of an existing node in the scene. This is a reversible write operation (the duplicate can be deleted), not destructive. The blast radius is medium since misuse could clutter the scene with many unwanted duplicates.

RECOMMENDED RULE

The rule that runs duplicate_node safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Cocos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For duplicate_node, this is the rule to start with:

duplicate_node Rate-limited

duplicate_node 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 Cocos, apply this rule, and every duplicate_node call is checked against it from then on.

FAQ

Questions about duplicate_node

Duplicate a node. It is categorised as a Write tool in the Cocos MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on duplicate_node? +

Register the Cocos MCP server in PolicyLayer and add a rule for duplicate_node: 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 Cocos. Nothing to install.

What risk level is duplicate_node? +

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

Can I rate-limit duplicate_node? +

Yes. Add a rate_limit block to the duplicate_node 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 duplicate_node completely? +

Set action: deny in the PolicyLayer policy for duplicate_node. 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 duplicate_node? +

duplicate_node is provided by the Cocos MCP server (caravanglory/cocos-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
