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

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

## Why drive_restore is rated Medium

This tool creates or modifies data reversibly by restoring a prior version and committing it as a new version. While it changes state, the operation is reversible (prior versions remain accessible) and does not permanently delete data. This qualifies as Write rather than Destructive.

From the tool's own definition: "The tool description states 'Restore a drive to a prior version (commits a new version; nothing is lost).' This operation modifies the state of a drive by reverting it to a prior version, which is a reversible write operation."

## Use case

AI agents use drive_restore to create or update resources in Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp environment.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "drive_restore": {
      "limits": [
        {
          "counter": "drive_restore_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
