Overview

Read events from iCloud calendars via CalDAV. Connect with an Apple app-specific password.

Prerequisites

An Apple ID with iCloud Calendar enabled
Ability to generate an app-specific password (two-factor authentication required)
A stackgate.ai account

Getting credentials

Sign in at appleid.apple.com → Sign-In and Security → App-Specific Passwords.
Generate a new password labeled e.g. "stackgate.ai".
In stackgate.ai, open Integrations → iCloud Calendar.
Click Activate, then Connect iCloud Calendar.
Enter your Apple ID email and the app-specific password (not your main Apple ID password).
After connect, select which calendars MCP may access.

Using with AI clients

Dedicated endpoint: POST /mcp/icloud-calendar
Private gateway: icloud-calendar__* tools

CalDAV runs on the cloud hub - no local CLI required.

Troubleshooting

Authentication failed — use an app-specific password, not your regular Apple ID password.
Slow list-events — large calendars sync many .ics files; narrow the date range when possible.
No calendars shown — open calendar preferences and enable at least one calendar.
