## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "local_ydb_cleanup_storage",

## Why local_ydb_cleanup_storage is rated Critical

This tool permanently deletes data from storage paths or Docker volumes. While it includes a safeguard (requires confirm=true to actually execute, and returns a plan first), the core function is irreversible destruction of data. This is clearly destructive rather than write (which is reversible) or execute (which may have variable effects).

From the tool's own definition: "'Delete only the explicitly supplied local-ydb host paths or Docker volumes' — the tool explicitly performs deletion of storage paths/volumes, which is irreversible data destruction."

## Use case

AI agents call local_ydb_cleanup_storage to permanently remove resources in Local Ydb, 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 Local Ydb:

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