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.Choose OAuth or a service account
The connection picker offers two routes:
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
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:
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 tool and choose GCP access token (with Service Account Key).
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.
