Apple PIM (EventKit, Contacts & Mail)

Overview

Apple provides frameworks and scripting interfaces for personal information management:

• EventKit: Calendars and Reminders
• Contacts: Address book management
• Mail.app: Local email via JXA (JavaScript for Automation) and AppleScript

EventKit and Contacts require explicit user permission via privacy prompts. Mail.app requires Automation permission and must be running.

For detailed API property tables and code examples, see:

• references/eventkit-api.md — EKEvent, EKReminder, EKCalendar, recurrence rules, alarms
• references/contacts-api.md — CNContact, labeled values, groups
• references/mail-jxa.md — JXA message properties, batch fetching, Mail.app vs Fastmail scope

Authorization & Permissions

Permission Model

Each PIM domain requires separate macOS authorization:

Domain	Framework	Permission Section
Calendars	EventKit	Privacy & Security > Calendars
Reminders	EventKit	Privacy & Security > Reminders
Contacts	Contacts	Privacy & Security > Contacts
Mail	Automation (JXA)	Privacy & Security > Automation

Authorization States

State	Meaning	Action
notDetermined	Never requested	Use apple-pim with action authorize to trigger prompt
authorized	Full access granted	Ready to use
denied	User refused access	Must enable in System Settings manually
restricted	System policy (MDM, parental)	Cannot override
writeOnly	Limited write access (macOS 17+)	Upgrade to Full Access in Settings

SSH Sessions

Permissions must be granted on the Mac where the CLI runs. SSH does not inherit GUI-level permission dialogs. Grant permissions locally first.

Configuration (PIMConfig)

The PIM CLIs share a configuration system for filtering calendars/reminder lists and setting defaults.

Config File Locations

Path	Purpose
~/.config/apple-pim/config.json	Base configuration
~/.config/apple-pim/profiles/{name}.json	Named profile overrides

Example Config

{
  "calendars": {
    "enabled": true,
    "mode": "blocklist",
    "items": ["US Holidays", "Birthdays"],
    "default": "Personal"
  },
  "reminders": {
    "enabled": true,
    "mode": "allowlist",
    "items": ["Tasks", "Shopping", "Work"],
    "default": "Tasks"
  },
  "contacts": {
    "enabled": true
  },
  "mail": {
    "enabled": true
  }
}

Domain Filter Config

Field	Type	Description
enabled	boolean	Whether the domain is active (default: true)
mode	string	Filter mode: all, allowlist, or blocklist (default: all)
items	string[]	Calendar/list names for allowlist or blocklist
default	string	Default calendar or list for creating new items

Filter Modes

Mode	Behavior
all	No filtering — all calendars/lists are visible (default)
allowlist	Only calendars/lists named in items are visible
blocklist	All calendars/lists are visible EXCEPT those named in items

Profiles

Profiles allow different configurations for different contexts (e.g., work vs personal).

Selection priority: --profile CLI flag > APPLE_PIM_PROFILE env var > base config only.

Merge semantics: A profile replaces entire domain sections. If a profile defines calendars, it completely replaces the base calendars config (not a field-by-field merge).

Discovery Tools

• apple-pim with action config_show: Returns the current resolved config after profile merging. Shows domains, filters, defaults, and paths.
• apple-pim with action config_init: Lists all available calendars and reminder lists from macOS with their sources and system defaults. Does NOT write any files.

Both accept an optional profile parameter.

Defaults Resolution

When creating events or reminders, the default calendar/list is resolved in this order:

1. Explicit --calendar or --list parameter
2. Config default value for the domain
3. System default calendar/list from EventKit

Note

There is no MCP tool for writing config files. Users must manually create or edit ~/.config/apple-pim/config.json. Use apple-pim with action config_init to discover available calendars/lists, then guide the user on creating the config.

Trusted Senders (auth_check)

The auth_check action verifies sender identity by parsing Authentication-Results headers (DKIM + SPF) against a trusted senders config.

Config file: ~/.config/apple-pim/trusted-senders.json

{
  "version": 1,
  "trustedSenders": [
    {
      "name": "Alice",
      "emails": ["[e-mail]"],
      "expectedDkimDomains": ["example.com"],
      "requireDkim": true,
      "requireSpf": true
    }
  ]
}

Override path with trustedSenders parameter: mail({ action: "auth_check", id: "<msg-id>", trustedSenders: "~/custom/senders.json" })

Best Practices

Calendar Management

1. Use default calendar for new events when user doesn't specify
2. Preserve recurrence rules when updating recurring events
3. Handle .thisEvent vs .futureEvents span for recurring event edits (see EKSpan below)
4. Check allowsContentModifications before attempting writes
5. Use calendar with action batch_create when creating multiple events for efficiency

EKSpan for Recurring Events

EventKit uses EKSpan to control which occurrences are affected by save/delete operations:

Span	Effect	When to Use
.thisEvent	Affects only the single occurrence	Default for delete and update. Use when cancelling one meeting.
.futureEvents	Affects this and all future occurrences	Use when ending a series or changing the pattern going forward.

• Delete: Default is .thisEvent. Pass --future-events to use .futureEvents.
• Update: Default is .thisEvent. Pass --future-events to apply changes to all future occurrences.
• Remove recurrence: Pass recurrence: { frequency: "none" } with --future-events to convert a recurring event into a single event.

Recurrence Output

When reading events/reminders, the recurrence array includes:

• frequency: daily, weekly, monthly, yearly
• interval: repeat every N periods
• daysOfTheWeek: which days (e.g., ["monday", "wednesday", "friday"])
• daysOfTheMonth: which days of month (e.g., [1, 15])
• endDate or occurrenceCount: when the series ends

Reminder Management

1. Default to incomplete reminders when listing
2. Use filters for focused views: overdue for urgent items, today for daily planning, week for weekly review
3. Set completionDate when marking complete
4. Respect priority levels (1=high is flagged in UI)
5. Use dueDateComponents not absolute dates for better handling
6. Use batch operations (reminder with action batch_complete, batch_delete) when acting on multiple items

Contact Management

1. Use unified contacts for consistent view across accounts
2. Preserve existing data when updating (only modify changed fields)
3. Handle labeled values carefully - don't lose non-primary entries
4. Request minimum necessary keys for performance

Mail Management

1. Mail.app must be running for all operations
2. Use batch operations (mail with action batch_update, batch_delete) for inbox triage
3. Use filters (unread, flagged) for efficient message listing
4. Message IDs are RFC 2822 — stable across mailbox moves
5. Use mailbox/account hints when available for faster lookups
6. Send (mail with action send) uses AppleScript — supports to, cc, bcc, from (account selection), subject, body
7. Reply (mail with action reply) preserves threading — looks up message by RFC 2822 ID, then uses Mail.app's reply verb
8. Auth check (mail with action auth_check) verifies DKIM/SPF against ~/.config/apple-pim/trusted-senders.json — returns verified, suspicious, untrusted, or unknown

Error Handling

1. Check authorization first with apple-pim action status when encountering errors
2. Use apple-pim action authorize to request access for notDetermined domains
3. Guide users to System Settings for denied domains
4. Validate dates before creating events/reminders
5. Check for conflicts when scheduling
6. Provide clear feedback on operation success/failure

Common Patterns

Date Parsing

Support flexible input:

• ISO 8601: 2024-01-15T14:30:00
• Natural language: "tomorrow at 3pm"
• Relative: "in 2 hours", "next Tuesday"

Time Zone Handling

• EventKit stores dates in UTC
• Display in local time zone
• Be explicit about time zones in user output

Searching

• Name search: CNContact.predicateForContacts(matchingName:)
• ID lookup: CNContact.predicateForContacts(withIdentifiers:)
• Date range: eventStore.predicateForEvents(withStart:end:calendars:)

Troubleshooting

Permission Issues

• Use apple-pim with action status to check all domains at once
• Use apple-pim with action authorize to trigger permission prompts
• Check System Settings > Privacy & Security
• Terminal/app must be granted access
• Restart app after granting permission

Configuration Issues

• Unexpected filtering: Use apple-pim with action config_show to verify the active config. Check if an unexpected profile is being applied via APPLE_PIM_PROFILE env var.
• Missing calendars/lists: Use apple-pim with action config_init to see all available calendars/lists from macOS, then compare with action config_show to see what's being filtered.
• Profile not applying: Check profile selection priority: --profile flag > APPLE_PIM_PROFILE env var > base config. Profile files must be at ~/.config/apple-pim/profiles/{name}.json.
• Malformed config: If config.json has invalid JSON, CLIs fall back to default behavior (all domains enabled, no filtering). Use apple-pim with action config_show to verify — it reports the config path and whether it was loaded successfully.

Missing Data

• Ensure keys are requested when fetching contacts
• Check calendar source/account sync status
• Verify iCloud sync is working

Performance

• Limit date ranges for event queries
• Use predicates to filter server-side
• Fetch only needed contact keys
• Use batch operations for multi-item actions
