## Why demo_vid_list is rated Low

The tool name pattern 'list' strongly indicates a data retrieval operation with no side effects. In the context of a video pipeline, this would retrieve metadata about existing demos or pipeline resources. The empty description prevents full certainty, but the semantic meaning of 'list' and the absence of keywords like 'delete,' 'create,' or 'execute' support classification as Read.

From the tool's own definition: "Tool name 'demo_vid_list' suggests a listing/enumeration operation typical of Read category tools. Description is empty, limiting certainty."

## Use case

AI agents call demo_vid_list to retrieve information from Demo Vid 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 Demo Vid:

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