WHAT IT DOES

What paste_node does on Cocos

AI agents use paste_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 paste_node is rated Medium

Pasting nodes creates new node instances in the scene based on previously copied data. This is a reversible write/create operation (nodes can be deleted after pasting). It does not execute code, destroy existing data, or involve financial transactions.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs paste_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 paste_node, this is the rule to start with:

paste_node Rate-limited

paste_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 paste_node call is checked against it from then on.

FAQ

Questions about paste_node

What does the paste_node tool do? +

Paste previously copied nodes. 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 paste_node? +

Register the Cocos MCP server in PolicyLayer and add a rule for paste_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 paste_node? +

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

Can I rate-limit paste_node? +

Yes. Add a rate_limit block to the paste_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 paste_node completely? +

Set action: deny in the PolicyLayer policy for paste_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 paste_node? +

paste_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.
