Broad accessThe tool can change data, run commands or handle secrets.

  • It creates, edits and deletes events and whole calendars, though deletion requires explicit confirmation
  • Deleting a calendar by a wrong or stale URL could hit the wrong data, so the URL is re-checked against a fresh list

This is third-party code. Review the repository files before installing.

What it does

The plugin talks directly to caldav.yandex.ru with no third-party server from the developer. In its MVP form it lists calendars, reads events for a period up to 366 days, creates a single event with an optional Yandex Telemost link, edits title, time, description and location, deletes an event or a whole calendar only after explicit confirm=true, and detects an ETag conflict to avoid overwriting a newer version of an event changed elsewhere. Editing recurrence rules, replying to invitations, bulk operations and OAuth for arbitrary accounts are deliberately out of the first version. The delete-calendar tool only accepts an exact URL from a fresh list, re-checks it against Yandex, and separately protects the primary and last remaining calendar from deletion.

Who it is for. For Codex users who want local, middleman-free access to Yandex Calendar with careful delete behavior.

Good fit when

  • You want direct access to Yandex's CalDAV with no third-party cloud server between the agent and the calendar
  • You care that deleting an event or calendar requires explicit confirmation
  • The MVP basics are enough: reading, creating, editing and deleting single events

Not a fit when

  • You need recurrence rule editing, invitation replies or bulk operations: none of that exists yet
  • You need listing in the official ChatGPT directory: the author explicitly says that is a separate, not-yet-ready plan

Example request

Show my meetings for today and create a tomorrow 11am event with a Telemost link

Limitations

This is a version 0.1 MVP with a deliberately narrow feature set, no recurrence rules, invitation replies or bulk operations. You need a Yandex app password of the Calendar type; a regular account password does not work. The private credentials file must have 0600 permissions, or the plugin refuses to read it. External HTTP is forbidden; requests go only to the configured caldav.yandex.ru origin.

How to disable. Remove the plugin with codex plugin remove yandex-calendar and, if needed, delete ~/.config/yandex-calendar-plugin/credentials.json.

FAQ

Can an event be deleted without confirmation?

No, deleting an event or calendar requires an explicit confirm=true and is marked as a destructive action.

Can the plugin delete the last remaining calendar?

No, delete_calendar separately protects the primary and last remaining calendar from deletion.
