## Why delete_database is rated Critical

This tool irreversibly destroys data at scale (entire database). Misuse by an AI agent could result in permanent loss of all data, schemas, and indices in a production database. This is the most severe risk category—Destructive—as it represents data loss that cannot be reversed through normal means.

From the tool's own definition: "delete_database performs irreversible deletion of an entire Firestore database. The verb 'delete' combined with the scope 'database' indicates a destructive action that cannot be undone."

## Use case

AI agents call delete_database to permanently remove resources in Mcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mcp:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_database"
  ]
}
```
