Claude Google Calendar connectorWhat Claude can do in your Google Calendar account.
The Claude Google Calendar connector exposes 9 tools. 5 of them read your calendars, 4 change them, and none is undocumented. Below: what Claude sees in your schedule, what it can book or cancel, what it asks first, and why one official page still says it cannot write.

What changes once Claude can see your calendar
Scheduling stops being a back-and-forth between tabs. You ask Claude what your week looks like, or when three colleagues are all free, and it reads your Google Calendar to answer, shared calendars you can access included. Then, if you want, it books the meeting too.
Know what is coming before Monday starts. Claude uses list_events and search_events to pull the week ahead, including shared calendars you can open, and flags the meetings that clash.
Find a slot that works for everyone. suggest_time looks for mutual availability across attendees, then create_event puts the meeting in the calendar once you agree on the time.
Keep the calendar honest. When a meeting moves, update_event changes it; when it dies, delete_event removes it; and respond_to_event accepts, declines or marks an invitation as tentative.
What the connector does not do: it never acts on its own. No tool wakes up when an invitation lands or ten minutes before a meeting; Claude only calls them while it answers you. It also stays inside the calendars your Google account can already open. If you want something to happen automatically on a calendar event, that is a job for an automation platform, covered on our Google Calendar n8n integration and Google Calendar Make integration pages. Different job, not a better one. The Claude gmail connector page covers the email side of the same Google account.
Five words to know before you connect
The vocabulary around this connector, in one minute.
- Connector
- A link you set up once between Claude and an account you already own, so Claude can work in it while it answers you.
- Tool
- One named action a connector hands to Claude. Claude picks the tools it needs by itself; the directory lists every one by name.
- Authorization
- Google's own sign-in and permission screen, where you give Claude its access. Granted once per person, and you can revoke it.
- Approval
- The go-ahead Claude waits for in the conversation before it does something that changes your calendar, like booking a meeting.
- MCP
- The open standard connectors run on: it is what lets an assistant like Claude talk to an outside service such as Google Calendar.
Connect Google Calendar to Claude in three steps
- 01
Open your connectors
In Claude, go to Customize then Connectors and find Google Calendar in the list. On a Team or Enterprise workspace, it only shows up once an Owner or Primary Owner has enabled it for the organization.
- 02
Click Connect and sign in to Google
Click Connect on the Google Calendar row, then sign in to your Google account in the window Google opens. When it works, the button turns into Disconnect, which is also how you reset a broken link.
- 03
Review Google's permission screen
Google lists what the access will cover before you accept. That screen belongs to Google, not to Claude, and it sets the scope. You can remove the access later from your Google account settings too.
The 9 tools, split by what they do
Google Calendar gives Claude 9 tools: 5 that read your account, 4 that change something in it.
Two groups: what Claude reads in your calendars, and what it changes. Tool names stay exactly as Claude shows them.
- 5 read
- 4 write
What Claude reads (5)
5 toolsFive tools that look at your schedule and leave it untouched.
get_event
Opens one event in full: time, place, description and the list of attendees, so Claude can brief you on it rather than guess from the title.
list_calendars
Shows which calendars your account can reach, yours and the shared ones, so Claude knows where to look before it searches.
list_events
Pulls the events over a stretch of time, a day, a week or a month, which is what Claude reads when you ask what your schedule looks like.
search_events
Searches your calendar for events, so Claude can go looking for a meeting you only half remember, across the calendars your account can open.
suggest_time
Looks for mutual availability across several attendees and proposes slots where everyone is free, instead of you comparing calendars by eye.
What Claude changes (4)
4 toolsFour tools that add, edit, remove or answer events. No source details a confirmation per tool, so the general approval rule applies.
create_event
Approval: see the ruleAdds a new event to your calendar with its time, title, guests and details, the step that turns a found slot into a booked meeting.
delete_event
Approval: see the ruleRemoves an event from your calendar. The help center lists deleting alongside creating and updating events.
respond_to_event
Approval: see the ruleAnswers an invitation for you: accept, decline or tentative. These three answers are the ones the help center names.
update_event
Approval: see the ruleChanges an event that already exists: new time, new room, an extra guest, a corrected description.
What Claude asks before it touches your calendar
Four of the nine tools change your calendar, so the approval rule matters here.
By default, every action Claude takes on your behalf waits for your explicit approval, shown in the conversation. The help center gives that rule for Google Workspace as a whole and does not detail it tool by tool for Calendar. On Team and Enterprise workspaces, owners decide whether members may let some actions run without a prompt each time, and they can limit the connector for the whole organization, reading only for instance. Claude also mirrors your Google permissions: a calendar you cannot open stays closed to it.
Which plans include the Google Calendar connector
None of the 819 directory sheets shows plan availability, so a connector-by-connector answer does not exist anywhere in official form.
The published rule is general: remote connectors are open to all users on Claude, Cowork, Claude Desktop and mobile, and desktop extensions install on Claude Desktop. On Team and Enterprise, an Owner or Primary Owner enables the connector for the organization before members can sign in. Official pages about the Google connectors do not all agree on plans, so for the current state on your account, check the Google Calendar sheet in the directory.
What the connector will not do
A connector does not watch your calendar: its tools only run while Claude is answering you, never when an invitation arrives on its own.
The directory's verification badge is not a security audit, and Anthropic says on every sheet that it does not decide which tools a publisher exposes or promise they behave as described. Here the publisher is Google itself, a known name. Beyond that, the limits are practical ones: most are set by Google's side of the connection, the rest by your own access rights. Keep in mind too that the rule for approvals is published for Google Workspace as a whole, not tool by tool for Calendar.
Can Claude create, change or delete events in Google Calendar?
- Developer documentation ↗September 2026Out of dateThe connector only reads: Claude cannot create, modify or delete events, nor send invitations.
- Help center ↗September 2026Claude creates, updates and deletes events, and answers invitations.

What this page followsYes, it writes to your calendar. The help center and the directory's tool list agree, and this page follows them. The developer page describes an older, read-only state, the same mistake it made about Gmail, and is set aside here.
