## Why PostgreSQL_get_backup_status is rated Low

This tool retrieves and queries backup and WAL archiving metadata from the PostgreSQL system. It performs no side effects, does not modify data, execute code, delete anything, or commit financial obligations. It fits the Read category: retrieves or queries data with no side effects.

From the tool's own definition: "Tool name and description indicate it 'Get[s] the last known backup status and WAL archiving information' — purely retrieval of existing status data with no modification, deletion, or execution of operations."

## Use case

AI agents call PostgreSQL_get_backup_status to retrieve information from Postgres 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 Postgres:

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