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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "reschedule_maintenance",
    "arguments": {
      "name": "<name>",
      "rescheduleType": "<rescheduleType>"
    }
  }
}
```

## Why reschedule_maintenance is rated Medium

Rescheduling maintenance modifies the scheduled maintenance window for an instance. This is a reversible configuration change (it can be rescheduled again) that doesn't delete data or execute arbitrary code, placing it firmly in the Write category. Misuse could cause unintended maintenance windows affecting availability, hence medium severity.

From the tool's own definition: "Reschedule maintenance for a Memorystore for Valkey instance"

## Use case

AI agents use reschedule_maintenance 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": {
    "reschedule_maintenance": {
      "limits": [
        {
          "counter": "reschedule_maintenance_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
