Using Cowork on 3P with Microsoft Foundry
Configure Cowork on 3P to use Claude models on Microsoft Foundry
To use Microsoft Foundry (Azure AI Foundry) as the inference provider, set inferenceProvider to foundry and supply the resource name and credentials (API key, credential helper, or Entra ID sign-in) described below.
[!NOTE] In this preview platform integration, Claude models on Microsoft Foundry run on Anthropic's infrastructure. This is a commercial integration for billing and access through Azure. The data-residency and "no conversation data sent to Anthropic" statements elsewhere in these pages do not apply when using Microsoft Foundry. See the Overview for details.
Configuration keys
| Setting | Required | Description |
|---|---|---|

Azure AI Foundry API keyinferenceFoundryApiKey |
For static auth | API key for the Foundry resource. May be supplied dynamically by an inferenceCredentialHelper executable instead. |
Entra ID tenant IDinferenceFoundryTenantId |
For interactive sign-in | Directory (tenant) ID of the Entra ID app registration that has the Cognitive Services scope. Use with inferenceCredentialKind: "interactive" for per-user device-code sign-in instead of a shared API key. |

You must also set inferenceModels to a list of Foundry deployment names. See the Configuration reference.
Configure in the app
Open the in-app configuration window (Developer → Configure third-party inference). In the Connection section, set Inference provider to Foundry, then fill in the Foundry credentials card:
| Field | Value |
|---|---|
| Azure AI Foundry resource name | your-foundry-resource |
| Azure AI Foundry API key | your API key |
Under Models, add at least one Model list entry using the Foundry deployment name.
Then click Export to produce a .mobileconfig (macOS) or .reg (Windows) file for your MDM. See Installation and setup for the export and deployment workflow.
