Connect Google Drive, Calendar, and Gmail

Connect Google Drive, Calendar, and Gmail to Claude Tag so it can read docs, sheets, events, and email. Covers OAuth setup, the service-account option, and what each grants.

Claude Tag is in public beta. Features and behavior described here may change before general availability.

Note: Connections are added inside an Access bundle. At claude.ai/admin-settings/claude-tag, open Access bundles in the left navigation, click into a bundle (or Create one), and go to its Credentials tab.

Connecting Google Drive, Calendar, and Gmail lets Claude read documents, spreadsheets, calendar events, and email from any channel under the bundle's scope. You add it as a connection inside an Access bundle; the credential belongs to the agent, not to any person.

This is an HTTP API connection, not a personal claude.ai connector. A member's own Google connector applies only in DMs.

Choose OAuth or a service account

The connection picker offers two routes:

Route	When to use
OAuth (Connect button)	Fastest path. An admin signs in with a Google account that has access to the content Claude needs.
GCP service-account key	When you want a dedicated non-human identity in Google with auditable access, or need domain-wide delegation across your Workspace.

Both routes create a credential and an allowed-websites rule path-scoped to that Google service (the Drive API path for Drive, the Calendar API path for Calendar, the Gmail API path for Gmail).

Add the connection with OAuth

Warning: Use a dedicated Google account for this connection (for example, claude@yourcompany.example.com), not your own. The connection is shared: anyone in a channel under the bundle's scope can ask Claude to read whatever this account can see in Drive, Calendar, and Gmail. A dedicated account starts with no access until you share the specific folders and calendars Claude needs, and keeps its activity under a separate identity in Google's audit log.

In the bundle, click Connect next to Google Drive, Google Calendar, or Google Gmail. A scope checklist appears with read-only scopes selected by default. Each scope grants a specific permission:

Scope	What it lets Claude do
openid, userinfo.email	Identify the connected account (selected by default)
calendar.readonly	Read events and calendars
calendar.events.readonly	Read events only (narrower than calendar.readonly)
calendar	Create, edit, and delete events
drive.readonly	Read files and folders
drive.file	Create and edit files Claude itself created
gmail.readonly	Read email

Check write scopes only if Claude should create or edit. Click Sign in with Google Calendar (or Sign in with Google Drive, or Sign in with Google Gmail), approve the Google consent screen, and the credential is saved.

The connection's reach is whatever the signed-in Google account can see. Share the relevant folders and calendars with that account in Google before testing.

Add the connection with a service account

In the bundle, click Connect another app at the bottom of the Credentials tab, then choose GCP access token (with Service Account Key).

Field	Value
GCP service account key (JSON)	The JSON key file from Google Cloud Console
Scopes (optional)	The Google API scopes to request (for example https://www.googleapis.com/auth/drive.readonly). The field is labeled optional, but Drive and Calendar calls fail without the matching scope listed here.
Subject (optional)	A user email to impersonate via domain-wide delegation. Set this for Workspace data (Drive, Calendar, Gmail, Docs).
Allowed websites	*.googleapis.com

For Google Workspace data (Drive, Calendar, Gmail, Docs), the service account needs domain-wide delegation configured in your Google Admin console with the matching API scopes. Google's guide is at developers.google.com/identity/protocols/oauth2/service-account.

The Agent Proxy injects the credential at the network boundary; the model and the sandbox are not given the key. See how Agent Proxy works.

Verify the connection

In a channel under the bundle's scope, in a new thread:

@Claude what can you access from this channel?

Google Drive, Calendar, or Gmail appears in the list once the connection is live. Connection changes can take a moment to reach a running thread; testing in a fresh thread is the reliable way to confirm.
