## Why get_index is rated Low

This tool retrieves information about a Firestore index. It performs a read-only query operation with no side effects, no data modification, and no resource deletion. The blast radius of misuse is minimal—an attacker could only learn about index configurations, not alter or destroy data. This is a straightforward Read operation.

From the tool's own definition: "Tool name is 'get_index' and description states 'Get a Firestore index.' The verb 'Get' indicates retrieval without modification."

## Use case

AI agents call get_index to retrieve information from Mcp 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 Mcp:

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