Access and checks

How we review

Extended accessThe tool runs code or makes network calls and only reads external data.

  • The create and delete tools change events in the user's personal calendar

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

What it does

The Python server connects to Yandex Calendar over CalDAV using a separate app password rather than the main account password. An agent can view upcoming events, create a new event and delete an existing one, with output in text or JSON. The README includes a video and GIF demo.

Who it is for. For Yandex Calendar users who want to manage events through Claude without the web interface.

Good fit when

  • You want a quick look at upcoming Yandex Calendar events
  • You want to create or delete an event by voice or text

Not a fit when

  • You need attendee invites or recurring events: the README does not describe these
  • You are not willing to create a separate app password in Yandex ID

Example request

Show my Yandex Calendar events for tomorrow and create a meeting at 3pm

Transport

Authentication

Environment variables

YANDEX_APP_PASSWORD required, secret
Yandex CalDAV app password, not the main account password

Limitations

The project is maintained by one author, with no pushes for over a year. It needs a CalDAV app password from id.yandex.ru/security/app-passwords, not the main account password. The README does not describe attendee invites or recurring events.

How to disable. Remove the server from your MCP client config and revoke the app password in Yandex ID settings.

FAQ

Can I use my main Yandex password?

No, the README explicitly warns against the main account password; you need a separate CalDAV app password for Calendar.
