# delete_instance

Delete an instance from a project. The request requires the 'name' field to be set in the format 'projects/{project}/instances/{instance}'. Example: { "name": "projects/my-project/instances/my-instance" } Before executing the deletion, you MUST confirm the action with the user by stating the full instance name and asking for "yes/no" confirmation.

## Why delete_instance is rated Critical

The delete_instance tool performs an irreversible deletion of a Bigtable instance, which cannot be undone. This is a destructive operation with potentially massive blast radius—an AI agent misusing this could wipe out production databases and cause severe data loss and business disruption.

From the tool's own definition: "Tool name is 'delete_instance' and description states 'Delete an instance from a project.' This irreversibly removes a Google Bigtable instance and all associated data."

## Use case

AI agents call delete_instance 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_instance"
  ]
}
```
