Deploy Claude Desktop on 3P with Google Cloud's Agent Platform

 
 The app always requests the `offline_access` scope so that the IdP returns a refresh token for silent renewal. If your IdP rejects `offline_access` on this client (for example, a PingFederate public client without the Refresh Token grant type enabled), set the `omitOfflineAccess` field of `inferenceVertexWorkforceOidc` to `true`. Without a refresh token the app cannot refresh silently, so users will be prompted to sign in again each time the IdP's ID token expires, typically about once an hour.
 
+When your IdP is Microsoft Entra ID, you can run this sign-in through the [OS identity broker](/docs/third-party/claude-desktop/entra-broker) on Windows and macOS instead of the system browser by setting `inferenceVertexWorkforceAuthFlow` to `broker`. The `issuer` in `inferenceVertexWorkforceOidc` must then be `https://login.microsoftonline.com/TENANT_ID/v2.0`, and no loopback redirect URI is needed. The token exchange at `sts.googleapis.com` is unchanged.

 ## Configure the app
 
 With Google Cloud set up and devices prepared, open the [in-app configuration window](/docs/third-party/claude-desktop/in-app-configuration#open-the-configuration-window) (**Developer → Configure Third-Party Inference…**) on an evaluation device. In the **Connection** section, set **Inference provider** to **Vertex AI** and fill in the **Vertex AI credentials** card with the values for whichever authentication approach you chose:
