reminders-mcp

MCP plugin exposing Apple Reminders to a Claude Code agent. Pure tool-based plugin (no channel events) — the agent calls these tools when it needs to view or modify reminders.

Used today by Mira on Luna for tracking Arshad's personal/work reminders that auto-sync to his iPhone via iCloud.

Tools

• list_lists() — return all Reminders lists on the system (e.g., Luna, Work, Home).
• list_reminders(list, include_completed?) — show reminders in a list (incomplete by default).
• create_reminder(list, title, notes?, due_date?, priority?) — add a reminder.
• complete_reminder(list, title) — mark a reminder done by list + title.
• delete_reminder(list, title) — remove a reminder by list + title.

The plugin wraps macOS Reminders via AppleScript / osascript. Tools that mutate require the macOS Automation permission to be granted to the terminal running Claude Code.

Requirements

• macOS (Reminders.app + AppleScript)
• iCloud signed in on the host (so reminders sync to Arshad's iPhone)
• Bun runtime
• Full Disk Access and Automation permissions for the terminal running Claude Code

Setup

bun install

Claude Code .mcp.json

{
  "mcpServers": {
    "reminders": {
      "type": "stdio",
      "command": "/Users/claudewala/.bun/bin/bun",
      "args": ["/Users/claudewala/luna-plugins/reminders-mcp/server.ts"],
      "alwaysLoad": true
    }
  }
}

No env vars needed — the plugin discovers Reminders lists at runtime.

Scope notes

• Luna-only by design — iCloud Reminders is a macOS-native feature. Linux hosts (titan, ariel, dione, janus) can't access it.
• Currently wired for Mira only. Other luna agents could use it if their workflow needs reminder management, but it's not in their default tool surface.
• The iCloud-Reminders ↔ iPhone sync is one-way visibility — reminders created here show up on Arshad's iPhone within seconds, and vice versa.
