## Why calendar_list_events is rated Low

This tool queries and retrieves calendar event information within a specified date range. It performs a read-only operation that does not create, modify, delete, or execute any actions. The only risk is exposure of calendar data (user schedules, events, attendees), which is sensitive but not high-blast if an agent queries it since reading alone causes no irreversible harm.

From the tool's own definition: "Tool name 'calendar_list_events' and description 'List calendar events in a date range' indicate data retrieval with no modification or side effects."

## Use case

AI agents call calendar_list_events to retrieve information from Apple Apps MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Apple Apps MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "calendar_list_events": {}
  }
}
```
