Validate current scene for issues

## Facts

- Tool: `validate_scene`
- 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": "validate_scene",
    "arguments": {}
  }
}
```

## Why validate_scene is rated Low

The validate_scene tool performs a diagnostic check on the current scene to identify issues. This is a non-destructive, side-effect-free query operation. It retrieves and analyzes scene data to report problems but does not create, modify, delete, or execute external operations. The tool is purely informational and fits the 'Read' category for operations that retrieve or query data without side effects.

From the tool's own definition: "Tool name 'validate_scene' and description 'Validate current scene for issues' indicate a validation/checking operation. Validation is inherently a read-only operation that inspects the scene state without modifying, deleting, or executing arbitrary code."

## Use case

AI agents call validate_scene 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": {
    "validate_scene": {}
  }
}
```

## 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`
