## Why GOOGLESUPER_LIST_TABLES is rated Low

This tool retrieves and queries the structure of a Google Spreadsheet to enumerate tables. It performs read-only analysis with no ability to modify, delete, or execute operations. The blast radius of misuse is minimal—an AI agent could discover spreadsheet contents but cannot alter or act upon them.

From the tool's own definition: "Tool name contains 'LIST' and description states 'list all tables' and 'Discover all tables' — purely retrieval operations with no modification or side effects."

## Use case

AI agents call GOOGLESUPER_LIST_TABLES to retrieve information from Google Super 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 Google Super:

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