Before you start

Claude already has a Google Calendar connector

Google's own connector is in the directory, verified, and it manages your schedule. This page's route is a different shape: the whole Google Calendar tool list behind one endpoint, with you choosing which of it Claude can touch.

Google Calendar Verified

14 tools Claude's connector directory with Google Calendar searched, showing the verified Google Calendar entry above a column of community ones.
In Claude: the plus icon, then Connectors, then Manage connectors. Open Discover and search for Google Calendar.

Versus

Connect FloConnector in five minutes

Connecting FloConnector connects Google Calendar, and Google Calendar is one of 60 connectors the same endpoint can carry. You do this setup once, not once per app.

  • Google Calendar tools, not one workflow The listing above does the job its vendor shipped it to do. A profile reaches all of them, and you switch on the handful you actually use.
  • One endpoint, not one app Google Calendar is one of 60 connectors a single profile can carry, so Claude answers across your stack rather than one app at a time.
  • You decide what it can change Reading and writing are separate switches. Leave the writes off and the connection cannot alter a record, however the question is put to it.

Step one

Connect Google Calendar

  1. Sign in to FloConnector and open Connectors, then choose Google Calendar.
  2. Choose Connect. Google's own account chooser opens, you pick the account whose calendars should be reachable and approve the permissions, then it returns you to the dashboard.
  3. Open a profile, or create one, and switch on the Google Calendar tools you want available. Keep the current-date tool on whatever else you choose, because everything about scheduling depends on it.
  4. Copy the profile's endpoint URL. That is the only thing you paste into Claude, and a profile with the booking tools left off gives you a look-but-do-not-touch endpoint.

Step two

Add the endpoint in Claude

  1. In Claude, open Settings, then Connectors.
  2. Choose Add custom connector.
  3. Give it a name you will recognise, such as your workspace name, and paste your profile endpoint as the URL.
  4. Save, then choose Connect. Claude opens the FloConnector sign-in page.
  5. Sign in with the email on your FloConnector account and approve access. Claude loads the profile's tools.

Control

Build the profile, then hand over the URL

A profile carries only the tools you switch on, and the endpoint exposes only that profile. That is the whole permission model, and it is set before anyone connects.

Tick a row to include it, or flip Read only to lock every write off at once.

FloConnector holds the Google Calendar credential, encrypted before it is stored, and calls Google Calendar on the model's behalf. Claude sees the tools and their results, never the credential behind them.

Once it is connected

What to ask Claude

Each of these runs real Google Calendar tools, named underneath so you can see what Claude is actually calling. 11 of the 45 tools are covered here.

Find me an hour with Priya and Sam next week when none of us are booked.

The gaps where all three calendars are clear in that window, worked out from today's real date rather than an assumed one.

  • get_current_date_time
  • list_calendars
  • find_free_slots

What have I got on tomorrow, across all my calendars?

Tomorrow's events from every calendar you subscribe to, merged into one list and shown in your own timezone.

  • get_current_date_time
  • events_list_all_calendars

Book the Meridian kickoff for Thursday at ten, invite the project team and put the dial-in in the description.

The event created with its attendees and description. Google sends the invitations from your account, because that is who the organiser is.

  • get_current_date_time
  • create_event

Move my Friday one-to-ones back an hour, all of them.

Each matching event shifted, one at a time, with the list read back so you can see exactly which ones moved.

  • find_event
  • patch_event

Which recurring meetings eat the most of my week?

Recurring series expanded into the instances that actually fall in the period and totalled by hours, so a fortnightly meeting is not counted as a weekly one.

  • events_list
  • events_instances

Set up a shared calendar for studio bookings and give the team edit access.

A new secondary calendar and one sharing rule per person, at the access level you asked for.

  • acl_insert
  • list_calendars

Troubleshooting

When Claude does not behave

  • Claude Desktop sits on Connect after you signed in

    The sign-in has usually succeeded. Check the profile in your dashboard: if the grant is there the connection is live, and restarting the desktop app clears the stale button. It is a client-side issue, not something the server can fix.

  • The connector saves but no tools appear

    Disconnect and reconnect it once. If it is still empty, check in the dashboard that the connection behind the profile is still connected and that you are an assigned member of that profile.

  • The first load is slow on a very large profile

    A profile exposing hundreds of tools takes longer to load, and a model given too many tools chooses worse. Split the work across two profiles rather than exposing everything at once. This is the failure mode most MCP write-ups name and never solve.

Questions, answered

Does Claude see my Google password?

No. You sign in on Google's own page and approve the permissions there. The token that comes back is encrypted before FloConnector stores it, and Claude only ever sees the tools and what they return.

Will it email people without asking me?

Creating an event with attendees sends Google's own invitation, and it goes out under your name because you are the organiser. That is Google's behaviour rather than a setting of ours. If you want Claude proposing times but not booking them, leave the event-creation tool off and it will tell you the slot instead.

Can it read my email as well?

No. This connector reaches Google Calendar and nothing else in the Google account. Gmail is a separate connector with its own permissions, and whether a profile carries it is your decision.

Can I keep my personal calendar out of it?

Two ways. Connect the work account rather than the personal one, or leave the all-calendars tool off so Claude looks only where you point it. Google's own sharing settings still apply on top of both.

Can my assistant use this on my behalf?

Anyone on the profile acts as the connected Google account and sees what it sees. If that is more than you want to hand over, connect a shared or delegated calendar account instead of your own and put them on that profile.

Does ChatGPT need a separate connection?

No, just the same URL in a different menu. A profile endpoint is a standard hosted MCP server, so nothing about the Google side changes.

The model has no clock of its own

Claude does not know what today is until something tells it, which is why the connector carries a tool that returns the current date and time in your timezone. Leave it switched on whatever else you enable. Without it, next Tuesday is a guess, and it is a guess that goes wrong most often on a Monday.

Finding a time for other people needs their calendars shared

Free and busy slots come back only for calendars the connected account can already see. A colleague who has not shared theirs is simply invisible, and Claude will cheerfully offer a slot that is not free at all. Share the calendars first, or keep the question to your own.

One tool empties a calendar

Clearing a calendar deletes every event on it, and nothing brings them back. It sits in the picker alongside the ordinary event tools and it is needed for nothing routine, so leave it off and there is no route to it.
