# snapshot_restore

Restore a directory to a recorded shadow-git snapshot. DESTRUCTIVE: files modified after the snapshot are overwritten, files created after it are DELETED, and files deleted after it are written back (full revert semantics). The isolated store never touches the project .git. Create a fresh snapshot_create first if you may need the current state.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "snapshot_restore",
    "arguments": {}
  }
}
```

## Why snapshot_restore is rated Critical

Irreversibly overwrites, deletes, and reverts files to a prior snapshot state.

From the tool's own definition: "files modified after the snapshot are overwritten, files created after it are DELETED"

## Use case

AI agents call snapshot_restore to permanently remove resources in Jshookmcp, 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 Jshookmcp:

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