# Apple Calendar MCP Server - Implementation Summary
## ✅ Implementation Complete
The Apple Calendar MCP server has been successfully implemented and is ready to use!
## What Was Built
### Core Components
1. **AppleScript Bridge** (`src/applescript/`)
- ✅ `bridge.ts` - Safe AppleScript execution wrapper
- ✅ `calendar-ops.ts` - Calendar CRUD operations (list, create, delete, rename)
- ✅ `event-ops.ts` - Event CRUD operations (create, read, update, delete, move)
2. **Utilities** (`src/utils/`)
- ✅ `date-parser.ts` - Natural language date parsing with chrono-node
- ✅ `conflict-detector.ts` - Smart scheduling algorithms
- Conflict detection
- Free time finding
- Optimal time suggestions
- Schedule analytics
3. **Storage** (`src/storage/`)
- ✅ `database.ts` - SQLite database for:
- Event templates
- Operation history (for undo)
- User settings/preferences
4. **MCP Server** (`src/server.ts`)

## Features
### Natural Language Date Parsing
- ✅ "tomorrow at 3pm"
- ✅ "next Friday"
- ✅ "in 2 hours"
- ✅ "Jan 15 at 10:30am"
- ✅ Common periods: "today", "tomorrow", "this_week", etc.
### Smart Scheduling
- ✅ Conflict detection with time slot overlap checking
- ✅ Free time finding with configurable intervals
- ✅ Business hours filtering (9am-5pm)
- ✅ Optimal time suggestions based on preferences
- ✅ Schedule analytics (meeting density, total time, daily breakdown)
### Data Persistence
- ✅ SQLite database for templates and history
- ✅ Default settings (default calendar: "life", 1-hour event duration)
- ✅ Operation history for undo support (last 100 operations)
## Configuration
### Claude Code Integration
✅ Configured in: `~/Library/Application Support/Claude/claude_desktop_config.json`
```json
{
"mcpServers": {
"apple-calendar": {
"command": "node",
"args": [
"/Users/josii/mcp-servers/calendar/dist/index.js"
]
}
}
}
```
### Default Settings (in SQLite)
- Default calendar: "life"
- Default event duration: 1 hour (3600000 ms)
- Business hours: 9am - 5pm

## Verification Results
All tests passed ✅
```
1. ✅ Apple Calendar access working
Available calendars: life, Home, Random, Scheduled Reminders,
Birthdays, Canadian Holidays, Siri Suggestions
2. ✅ Project built successfully
TypeScript compiled to dist/
3. ✅ Database created and initialized
4 default settings configured
4. ✅ MCP server configured in Claude Code
5. ✅ Natural language date parsing working
Example: "tomorrow at 3pm" → 2026-02-05T20:00:00.000Z
```
## How to Use
### 1. Start Using (Server Auto-Starts)
The server is configured to auto-start when Claude Code launches. Just restart Claude Code and the tools will be available.
### 2. Example Commands
**Calendar Management:**
```
"List my calendars"
"Create a calendar called Work"
"Rename Work to Office"
```
**Create Events:**
```
"Create event 'Team Meeting' tomorrow at 2pm"
"Schedule 'Dentist' next Tuesday at 10am for 1 hour"
"Add 'Coffee with Sarah' at Starbucks tomorrow at 3pm"
```
**Smart Scheduling:**
```
"Find free time tomorrow for a 1 hour meeting"
"Check if I'm free Friday at 3pm"
"Suggest the best time next week, I prefer mornings"
```
**Templates:**
```
"Create a template called 'standup' with 15 minute duration"
"Schedule a standup meeting tomorrow at 9am"
"List my templates"
```
**Analytics:**
```
"Analyze my schedule for this week"
"Show insights for next month"
```
## Technical Highlights
### Security
- ✅ Proper AppleScript string escaping (prevents injection)
- ✅ Input validation for all parameters
- ✅ Error handling for all Calendar operations
### Performance
- ✅ Efficient conflict detection algorithm
- ✅ Smart free time finding with 30-minute intervals
- ✅ Batch operations supported (list all events)
### Type Safety
- ✅ Full TypeScript implementation
- ✅ Strict type checking enabled
- ✅ All interfaces properly defined
### Reliability
- ✅ Comprehensive error handling
- ✅ Transaction support for database operations
- ✅ History tracking for undo support
## What's NOT Implemented (Future Enhancements)
The following were planned but can be added later:
1. **Recurring Events** - RRULE support for recurring patterns
2. **Attendees** - Managing event attendees and responses
3. **Reminders** - Setting custom reminders on events
4. **Bulk Operations** - Bulk delete, bulk move, bulk update
5. **Consolidation** - Calendar consolidation workflow
6. **Undo Command** - Explicit undo tool (history is tracked but no undo tool)
7. **iCal Import/Export** - Import/export .ics files
8. **Advanced Analytics** - ML-based categorization, work-life balance tracking
These can be added incrementally based on user needs.
