Dav Mcp
Gives Claude full CRUD access to any CalDAV, CardDAV, or VTODO server through 26 specialized tools. You can query calendars with server-side filters, update individual contact fields without touching the rest of the vCard, manage tasks with priority and due dates, and even create new calendar collections on the fly. Works with Nextcloud, Baikal, Radicale, and iCloud out of the box, plus Google Calendar via OAuth2. The field-agnostic updates are the real win here since you can modify any RFC property or custom X-* field without reconstructing entire iCal objects. Reach for this when you need AI-driven calendar orchestration beyond simple event creation, or when you want contacts and tasks in the same integration.
