WHAT IT DOES

What query_scene_classes does on Cocos

AI agents call query_scene_classes to retrieve information from Cocos without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why query_scene_classes is rated Low

This tool performs a read-only query to enumerate registered classes in the scene. It has no side effects, does not modify data, does not execute operations, and does not affect system state. The blast radius of misuse is minimal—at worst, an AI agent gains visibility into available classes, which is informational only.

From the tool's definition Tool name 'query_scene_classes' and description 'Query all registered classes' indicate a retrieval operation that lists or queries existing data without modification or execution of code.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

query_scene_classes Allowed

query_scene_classes is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "query_scene_classes": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Cocos, apply this rule, and every query_scene_classes call is checked against it from then on.
