assets · Cocos MCP: Risk & Policy

WHAT IT DOES

What assets does on Cocos MCP

AI agents invoke assets to trigger actions in Cocos MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why assets needs a policy

assets triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Verdict

assets Rate-limited

assets stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Cocos MCP, so you can run agents against it safely.

FAQ

Questions about assets

What does the assets tool do? +

assets. It is categorised as a Execute tool in the Cocos MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on assets? +

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

What risk level is assets? +

assets is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit assets? +

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

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

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