Query all registered classes

## Facts

- Tool: `query_scene_classes`
- Server: Cocos (`caravanglory/cocos-mcp-server`) — https://policylayer.com/tools/caravanglory-cocos-mcp-server.md
- Homepage: https://github.com/caravanglory/cocos-mcp-server
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "query_scene_classes",
    "arguments": {}
  }
}
```

## 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 own 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."

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Cocos:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
