This guide is for Google Workspace accounts (your organization’s Google). Set
your OAuth app’s user type to Internal — an internal app only your organization
can use, which skips Google’s app-verification review entirely.
Connector URLs
Add each service you want as its own connector, using these URLs:
You can use the same Client ID and Secret for all three.
Create the OAuth app
1
Create a Google Cloud project
In the Google Cloud console, create a project
(or reuse one) inside your Workspace organization.
2
Enable the Workspace MCP APIs
Under APIs & Services → Library, enable the APIs for the services you want:
gmailmcp.googleapis.com, drivemcp.googleapis.com, and
calendarmcp.googleapis.com.3
Configure the consent screen as Internal
Under APIs & Services → OAuth consent screen, choose Internal as the user
type and fill in the basic app details.
4
Create an OAuth client
Under APIs & Services → Credentials, create an OAuth client ID. Add the
redirect URI the Hub shows you in the connector setup to the client’s
authorized redirect URIs. Save, then copy the Client ID and Client Secret.
Connect in the Hub
1
Add the connector
Add a connector using the URL for the service you want (Gmail, Drive, or Calendar).
2
Paste your credentials
Enter your Client ID and Client Secret in the connector’s settings, then
click Connect.
3
Approve access
Your browser opens Google’s consent screen. Approve it, and the connector’s tools
load. Repeat for each service you added.
