Gives Claude full read/write access to macOS Calendar.app across all configured accounts (iCloud, Google, Exchange). Reads are fast SQL queries against Calendar's local SQLite database, including proper recurring event expansion via the OccurrenceCache table. Writes go through AppleScript so changes sync back to your accounts just like manual edits. Seven tools cover the full lifecycle: list and search events, get event details with attendees, create, update, and delete. Requires Full Disk Access and Automation permissions for the host process. Runs entirely local with no network calls or telemetry. Reach for this when you need Claude to schedule meetings, find conflicts, or manage your calendar without leaving the conversation.
