What is the Claude Google Calendar connector? Connecting your calendar, adding events, pricing and security

You connect Calendar with your Google account from Customize › Connectors; you ask Claude questions like "when am I free this week," and Claude looks at the events, attendees and free time in your calendar. It is an official connection; Claude works only when you ask for something and only within your own calendar permissions, and of shared calendars it sees only those you have access to. Two of Anthropic's pages contradict each other on whether Claude can create, change and delete events and send invitations, and on which plans include it; this guide shows both versions and explains how to check on your account.

What it does: Lets Claude look at your calendar and free time
Type: Official connector (remote MCP)
Writing events: Sources contradict each other

What does Claude's Google Calendar connector do?

The connector is an official connection that gives Claude access to your Google Calendar account. Once connected, you can ask questions like "what meetings do I have tomorrow?", "are there any conflicts next week?" or "who is attending the budget meeting?". Claude also sees shared calendars you have been given access to. Google's remote MCP server runs behind it (MCP is the standard AI programs use to connect to outside services).

The Help Center also lists creating, updating and deleting events, responding to invitations and setting up recurring meetings; Anthropic's pages contradict each other on these, so see the "Does it add events?" section below.

Who it helps: anyone with a packed calendar: consultants, team leads, business owners who work by appointment.

How do you connect Google Calendar to Claude?

You connect once, and the browser asks you to sign in with your Google account. The steps come from Claude's help pages.

Open claude.ai or Claude Desktop and go to Customize then Connectors.
Find Google Calendar and click Connect; sign in with your Google account and approve the permissions.
Once connected, the Connect button turns into Disconnect. In a chat, check that the Google Calendar toggle is on under + › Connectors, then ask a question about your calendar.

First connect your calendar on claude.ai (Customize then Connectors); it cannot be added in Claude Code with claude mcp add.
In Claude Code, sign in with your Claude account (/login); the connectors come over automatically. List them with /mcp.

The Claude Code documentation states that local OAuth is not supported for Gmail and Google Calendar. In sessions running on an API key or a cloud provider sign-in, claude.ai connectors are not loaded; check the active sign-in with /status.

First try"Look at my calendar: which afternoons am I free next week? Find a one-hour open slot between Tuesday and Thursday."

Can Claude add, change or delete calendar events?

Two of Anthropic's pages answer this question differently. The Claude Help Center and the connector directory list creating, updating and deleting events and responding to invitations. The Calendar page in Claude Docs, however, describes the connector as read-only.

Action	Help Center and directory	Claude Docs Calendar page
Viewing events and calendars, shared calendars	Available	Available (only calendars you have access to)
Finding shared free time	Available	Not stated
Creating and updating events, recurring meetings	Available	Says it "cannot create or modify"
Deleting events	In the directory listing (delete_event)	Says it "cannot delete"
Responding to invitations (accept, decline, maybe)	Available	Says read-only
Sending invitations	Attendee list management available	Says it "cannot send invitations"

Check on your own account. Look at the tool list under Customize then Connectors then Google Calendar then Tool permissions. If tools named create_event, update_event, delete_event and respond_to_event are there, write tools are defined on your account.
Turn them off if you don't want them. Set the write tools to "Needs approval" or "Blocked".
Be careful with events that have attendees. The official sources don't say whether an invitation email goes out when attendees are added to an event; for important meetings, check in your calendar yourself that the invitation went out.

Google's own reference page also lists write tools, but the OAuth permission scopes on that page are read-only. This is a detail of Google's own manual setup route; it is not decisive for Claude's ready-made connector.

Of calendars shared with you, only those you have access to
Attendees' free time (if you have access)

Writes and deletes

Tools for creating, updating, responding to and deleting events are in the directory listing; Claude Docs describes the connector as read-only. By default it asks for approval before write actions.

Which account, which permissions

Claude accesses only the calendar data of the Google account you connected and cannot go beyond your existing permissions in Google. It works only when you ask for something and with the minimum information needed.

Model training and retention

Anthropic states that it does not train its models on Gmail, Drive and Calendar connector data; the exception is content you copy and paste into a chat if you allowed training on a consumer plan. Retrieved data is stored on Anthropic's servers with the chat; deleting the chat also deletes the data.

One Google account

Reported by users Users report that connecting a second Google account replaces the first. The official page does not state a limit explicitly.

Both Anthropic and Google warn that an AI session can be steered by instructions hidden in event descriptions or invitations from untrusted sources (prompt injection). When you have Claude process invitations from people you don't know, keep the write tools on approval. This is not a security certification.

Is the Google Calendar connector free?

No official page lists a separate charge for the connector. The sources do, however, contradict each other on which Claude plans include it. A Google account is required.

Source	What it says
Claude Help Center (Google Workspace connectors)	The Gmail, Calendar and Drive connectors are for "all users" on Claude and Claude Desktop
Claude Docs: Calendar page	On Pro, Max, Team and Enterprise plans
Claude pricing page	The "Connectors" row says "Yes" for Free, Pro and Max; the row is general, not specific to Calendar
Google's own MCP route (manual setup)	Requires an Enterprise, Pro, Max or Team plan on the Claude side

Open the Customize then Connectors list on your account and look for Google Calendar.
If you see a Connect button, try connecting.
On Team and Enterprise, if it is not in the list, the Owner or Primary Owner has not enabled the connector for the organization.

This guide does not say whether the Calendar connector is or isn't on the free plan; the sources don't make it clear.

Does the Calendar connector work with Turkish events?

Reading and summarizing Turkish eventsUnclear	The official sources make no connector-specific commitment for Turkish. Claude's help page says in general that it replies in the language you write in.
Claude's interface languageUnclear	Claude's official language page (August 6, 2026) does not list Turkish; the Claude guide notes that a Turkish menu was seen in the settings of a paid account on October 14, 2026.
Access from TurkeyYes	Turkey is on Anthropic's list of supported regions (page dated May 12, 2026).

Common problems and fixes

What happens	What to do
I connected it, but Claude doesn't use my calendar	In each chat, check that the Google Calendar toggle is on under + › Connectors. On a team account, the Owner must have enabled the connector.
"You may need to reconnect with your Google account" error	Customize then Connectors then Google Calendar then Disconnect (Disconnect again in the confirmation). Google will ask you to sign in again next time. If that doesn't fix it, find Claude at myaccount.google.com/connections and choose "Delete all connections".
"Access blocked: your institution's admin needs to review Claude"	The Google Workspace admin must mark Claude as "Trusted" (admin.google.com › Security › Access and data control › API controls › Manage third-party app access); wait about 15 minutes.
Calendar isn't in the list on a team account	The Owner or Primary Owner must enable the connector under Organization settings then Connectors.
Claude can't create events or says it is "read-only"	The sources contradict each other. Check whether create_event and update_event are in the Customize then Connectors then Google Calendar then Tool permissions list; if not, add the event yourself.
Calendar doesn't show up in Claude Code	Connect your calendar on claude.ai, sign in to Claude Code with your Claude account via `/login`, and confirm with `/status` that the active sign-in is your claude.ai subscription. Adding it with `claude mcp add` does not work.

How do you disconnect Calendar?

Disconnect in Claude. Customize then Connectors then Google Calendar then Disconnect; click Disconnect again in the confirmation window.
To turn it off in just one chat, switch off the Google Calendar toggle under + › Connectors in that chat.
Revoke the permission on the Google side. Find the Claude connection at myaccount.google.com/connections, open its settings and choose "Delete all connections".

Once you disconnect, Claude loses access to your calendar; your calendar stays as it is in Google. Retrieved data is stored with the chat, so if you want it deleted, delete the related chats too.
