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

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",

## Why deleteCalendarEvent is rated Critical

This tool permanently removes calendar events, which cannot be undone. Deletion is irreversible data destruction, making it Destructive rather than Write. The severity is high because unauthorized deletion of calendar events could disrupt schedules, meetings, and coordination across an organization, though the blast radius is typically limited to calendar data rather than critical system infrastructure.

From the tool's own definition: "Tool name is 'deleteCalendarEvent' with description 'Delete a calendar event'. The verb 'delete' combined with calendar event data indicates irreversible removal of data."

## Use case

AI agents call deleteCalendarEvent to permanently remove resources in Google Drive, 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 Google Drive:

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