Yandex Calendar

List, create, update, RSVP to, move and delete Yandex Calendar events over CalDAV, with attendees, busy status and several calendars.

Good to know before installing

Sends every request to caldav.yandex.ru, or to the HTTPS URL in YANDEX_CALENDAR_BASE_URL if you set one, with your YANDEX_CALENDAR_LOGIN and YANDEX_CALENDAR_APP_PASSWORD read through Hermes; all seven tools, delete included, are offered unless YANDEX_CALENDAR_ACTIONS narrows them; the tools act as your Yandex account, so adding attendees makes Yandex email each of them an invitation from you, and changing, answering, moving or deleting a meeting may notify the people on it; delete removes the event from the server and the plugin keeps no copy; event text written by other people, such as whoever invites you, reaches the agent as tool output; no other endpoint, no telemetry, no file or shell access, no background process. Independent community plugin, not affiliated with Yandex.

From the plugin's catalog listing.

How to install

  1. Install it. Hermes asks for any API keys it needs (this one needs YANDEX_CALENDAR_LOGIN, YANDEX_CALENDAR_APP_PASSWORD), then asks whether to turn it on.
    hermes plugins install yandex_calendar
  2. Said no? Turn it on later:
    hermes plugins enable yandex_calendar
  3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
