Everything You Need

Native macOS PIM integration with 5 MCP tools covering Calendar, Reminders, Contacts, Mail, and system management.

📅

Calendar Management

List calendars, create/read/update/delete events, search by date or title, batch create, and full recurrence rule support.

✅

Reminder Management

List reminder lists, create/complete/update/delete reminders, smart filters (overdue, today, week), and batch operations.

👤

Contact Management

List groups, create/read/update/delete contacts, search by name/email/phone, birthday and relationship support.

📧

Mail Integration

List accounts and mailboxes, read/search/move/delete messages, update flags — all through Mail.app and JXA.

🔒

Per-Domain Control

Enable or disable entire domains independently, allowlist/blocklist calendars and reminder lists. Privacy-first design.

🤖

Multi-Agent Isolation

Per-call config and profile overrides, workspace isolation. Give each agent different PIM access for safe delegation.
