Run Server Directly

npm run start

Architecture

This MCP server uses a clean architecture:

  1. MCP Server Layer (index.ts): Handles MCP protocol communication
  2. AppleScript Executor (applescript-executor.ts): Manages all Reminders app interactions
  3. Type Safety: Zod validation and TypeScript for reliability

The AppleScript integration uses osascript for direct system integration, avoiding external dependencies and app translocation issues.

Troubleshooting

Permission Issues

If you get permission errors, ensure:

  1. Terminal (or your app) has Automation permissions for Reminders
  2. Go to System Preferences > Security & Privacy > Privacy > Automation
  3. Enable access for the app running this server

Date Format Issues

Due dates must use the format: "MM/DD/YYYY HH:MM AM/PM"

Examples:

  • "12/25/2025 9:00 AM"
  • "01/01/2026 11:30 PM"

Reminder IDs

Reminder IDs are system-generated Apple URLs (e.g., x-apple-reminder://...). They're not portable across systems but are stable within a single macOS installation.
