Google Calendar

What Claude can do

• Read calendars, events and availability
• Create or edit an event

No deletion. A write that carries real values (guests, title) waits for your approval in a system window, outside the chat.

Everything the service returns is coded before it reaches Claude.

Before you start

• A Google account.
• The Google access file, with these APIs enabled: Google Calendar API. The same file serves Gmail, Calendar and Drive.

Set up

1. Hidden Tokens dashboard → Connectors.
2. On the Google Calendar row, click Enable.
3. If the access file is not in place yet: Choose the Google access file… and pick it. It stays on this computer.
4. Click Sign in: your browser opens the Google page. Choose your account and accept.
5. Click Test. The status turns to “Ready”.

Try it in Claude

What are my meetings tomorrow?

Claude should use a agenda__… tool and answer with codes. To get the real values back in a text, ask Hidden Tokens to decode it: they come back on your computer, not in the chat.

Switch off the original connector

In Claude, Settings → Connectors and Extensions: switch off Google Calendar. Otherwise the AI can go through it, in clear.

Limits

• No deletion. A write that carries real values (guests, title) waits for your approval in a system window, outside the chat.
• If your Google Cloud project is in “testing” mode, Google expires the sign-in after 7 days: click Sign in again.
• Images and binary attachments are not passed to Claude: a pixel cannot be coded.
• Tried with a real Google account on a Mac (10 November 2026); not yet on Windows.
