## Why PostgreSQL_get_backup_details is rated Low

This tool only queries and returns backup status and WAL archiving information. It has no side effects, does not modify data, execute commands, delete records, or commit financial transactions. It is a straightforward read operation that retrieves diagnostic information about backup state.

From the tool's own definition: "Tool name contains 'get' and description states 'Get last known backup status and WAL archiving info' — purely retrieval of existing backup metadata with no modification, deletion, or execution of operations."

## Use case

AI agents call PostgreSQL_get_backup_details 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_details": {}
  }
}
```
