## Why get_frame_by_query is rated Low

This tool retrieves and queries existing data (video transcripts and frames) without side effects. It performs a search and content extraction, which are characteristic Read operations. The blast radius of misuse is minimal—an agent could retrieve unintended video content but cannot modify, delete, or execute arbitrary operations.

From the tool's own definition: "Tool description states it 'search[es] a video's transcript and extract[s] a frame' — both read-only operations. Transcript search queries data; frame extraction retrieves visual content. No modifications, deletions, or external executions."

## Use case

AI agents call get_frame_by_query to retrieve information from Mcptube Vision 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 Mcptube Vision:

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