Let AI assistants read your synced calendars

April 9, 2026 · v2.9.33

Keeper.sh can now be added as a connector in Claude and other assistants that support the Model Context Protocol (MCP). Once connected, the assistant can list the calendars you have linked, look up the events in a date range and timezone you give it, and count how many fall inside it, so "what does my Thursday look like" is answered from your actual calendars.

You approve the connection once, on a consent screen in your browser, and the assistant signs in with OAuth instead of holding a password. You can revoke its access at any time, and revoking it does not touch the calendars themselves.

At launch the connector is read-only: the assistant can look at your calendars but cannot change them.

How to give Claude access to your calendar walks through connecting it.

New

Visitors in the EU, EEA and UK are asked whether Keeper.sh may use analytics and advertising cookies, and the choice is remembered.

Improved

A connected assistant stays signed in considerably longer before it asks you to connect again.
A calendar you sync into that hits a passing error keeps retrying on the normal schedule instead of being switched off.

Fixed

Connecting Keeper.sh from Claude Desktop goes through, instead of failing before the approval screen.
Events no longer appear on your other calendars, vanish on the next sync, and come back again.
Copies of the same event no longer pile up, one more added on every sync.
Calendars that label times the Microsoft way, such as Eastern Standard Time, now arrive at the right hour.
An ordinary hiccup no longer flags a working account as needing to be reconnected.
A calendar deleted at your provider is switched off instead of failing on every run.
An empty or cut-short error from Google no longer stops the whole sync.
Your calendar list still loads when a provider declines to hand it over.
The checkout window on the upgrade page opens instead of coming up blank.
Starting a Microsoft 365 connection takes you to the Microsoft sign-in page instead of failing immediately.
An occurrence of a repeating meeting moved or retitled on a CalDAV calendar now comes across.
CalDAV servers that return unusable data for repeating events, Lark among them, now sync.
One event copied into two Google calendars is no longer treated as a duplicate of itself.
