WHAT IT DOES

What attach_script does on Cocos

AI agents use attach_script 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 attach_script is rated Medium

This tool modifies a node by attaching a script component to it. It creates/adds data to an existing node, which is a reversible write operation (the component can be removed). However, attaching an arbitrary script could have broader implications if the script executes code, though the tool itself is a write operation that adds a component reference.

RECOMMENDED RULE

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

attach_script Rate-limited

attach_script 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 attach_script call is checked against it from then on.

FAQ

Questions about attach_script

What does the attach_script tool do? +

Attach a script component to 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 attach_script? +

Register the Cocos MCP server in PolicyLayer and add a rule for attach_script: 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 attach_script? +

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

Can I rate-limit attach_script? +

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

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

attach_script 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.
