Authentication And Credential Management For Caldav

via “caldav protocol implementation with server discovery”

Calendar sync tool & universal calendar MCP server. Aggregate, sync and control calendars on Google, Outlook, Office 365, iCloud, CalDAV or ICS.

Unique: Implements full CalDAV protocol stack with automatic server discovery via DNS SRV and .well-known URIs, treating CalDAV as a first-class provider alongside OAuth2 APIs; includes WebDAV PROPFIND support for calendar enumeration

vs others: Supports self-hosted CalDAV servers natively without requiring cloud connectors, whereas most calendar aggregators (Fantastical, Outlook) require manual CalDAV URL entry and don't support automatic discovery
