caldav-mcp exposes calendar operations over CalDAV, the open standard most calendar servers implement — including Nextcloud, Radicale, Fastmail, iCloud and Google Calendar through its CalDAV endpoint. Because it speaks the protocol rather than a vendor API, one server works across providers and self-hosted installations. Its tools connect to a CalDAV server with the supplied credentials, list the available calendars on that account, list events within a specified timeframe, and create, update and delete events, with deletion identified by event id. Querying by timeframe rather than fetching everything is the right shape for the usual questions — what is on next Tuesday, is there a free hour on Thursday — since a full calendar export would be both slow and unusable in a context window. The server is TypeScript, published on npm as caldav-mcp with semantic-release automation, and MIT licensed. Its self-hosting appeal is concrete: someone running Nextcloud or Radicale can give an assistant calendar access without routing anything through a third-party service. The audience is people who keep their calendar on a CalDAV server and want scheduling handled in conversation — checking availability, adding an appointment, moving one.
