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

```json
{
  "jsonrpc": "2.0",

## Why quick_add_event is rated Medium

This tool creates new calendar events, which is a write operation that modifies calendar state. While calendar event creation is reversible (events can be deleted), the tool operates on user data with side effects. The natural language parsing aspect introduces moderate risk of unintended calendar commitments if the AI misinterprets user intent.

From the tool's own definition: "Tool name 'quick_add_event' and description 'Creates an event' indicate data creation. The tool adds calendar events, which are reversible modifications to calendar data."

## Use case

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