## Prerequisites¶
¶
Before configuring Claude Code with Microsoft Foundry, ensure you have:¶
¶
* An Azure subscription with access to Microsoft Foundry¶
* RBAC permissions to create Microsoft Foundry resources and deployments¶
* Azure CLI installed and configured (optional - only needed if you don't have another mechanism for getting credentials)¶
¶
<Note>¶
If you are deploying Claude Code to multiple users, [pin your model versions](#4-pin-model-versions) to prevent breakage when Anthropic releases new models.¶
</Note>¶
¶
## Setup¶
¶
### 1. Provision Microsoft Foundry resource¶
¶
First, create a Claude resource in Azure:¶
¶
1. Navigate to the [Microsoft Foundry portal](https://ai.azure.com/)¶
2. Create a new resource, noting your resource name¶
3. Create deployments for the Claude models:¶
* Claude Opus¶
* Claude Sonnet¶
* Claude Haiku¶
¶
### 2. Configure Azure credentials¶
¶
Claude Code supports two authentication methods for Microsoft Foundry. Choose the method that best fits your security requirements.¶
¶
**Option A: API key authentication**¶
¶
1. Navigate to your resource in the Microsoft Foundry portal¶
2. Go to the **Endpoints and keys** section¶
3. Copy **API Key**¶
4. Set the environment variable:¶
¶
```bash theme={null}¶
export ANTHROPIC_FOUNDRY_API_KEY=your-azure-api-key¶
```¶
¶
**Option B: Microsoft Entra ID authentication**¶
¶
When `ANTHROPIC_FOUNDRY_API_KEY` is not set, Claude Code automatically uses the Azure SDK [default credential chain](https://learn.microsoft.com/en-us/azure/developer/javascript/sdk/authentication/credential-chains#defaultazurecredential-overview).¶
This supports a variety of methods for authenticating local and remote workloads.¶
¶
On local environments, you commonly may use the Azure CLI:¶
¶
```bash theme={null}¶
az login¶
```¶
¶
<Note>¶
When using Microsoft Foundry, the `/login` and `/logout` commands are disabled since authentication is handled through Azure credentials.¶
</Note>¶
¶
### 3. Configure Claude Code¶
¶
Set the following environment variables to enable Microsoft Foundry:¶
¶
```bash theme={null}¶
# Enable Microsoft Foundry integration¶
export CLAUDE_CODE_USE_FOUNDRY=1¶
¶
# Azure resource name (replace {resource} with your resource name)¶
export ANTHROPIC_FOUNDRY_RESOURCE={resource}¶
# Or provide the full base URL:¶
# export ANTHROPIC_FOUNDRY_BASE_URL=https://{resource}.services.ai.azure.com/anthropic¶
```¶
¶
### 4. Pin model versions¶
¶
<Warning>¶
Pin specific model versions for every deployment. If you use model aliases (`sonnet`, `opus`, `haiku`) without pinning, Claude Code may attempt to use a newer model version that isn't available in your Foundry account, breaking existing users when Anthropic releases updates. When you create Azure deployments, select a specific model version rather than "auto-update to latest."¶
</Warning>¶
¶
Set the model variables to match the deployment names you created in step 1.¶
¶
Without `ANTHROPIC_DEFAULT_OPUS_MODEL`, the `opus` alias on Foundry resolves to Opus 4.6. Set it to the Opus 4.7 ID to use the latest model:¶
¶
```bash theme={null}¶
export ANTHROPIC_DEFAULT_OPUS_MODEL='claude-opus-4-7'¶
export ANTHROPIC_DEFAULT_SONNET_MODEL='claude-sonnet-4-6'¶
export ANTHROPIC_DEFAULT_HAIKU_MODEL='claude-haiku-4-5'¶
```¶
¶
Background tasks such as session title generation use the small/fast model, normally a Haiku-class model. On Foundry, Claude Code defaults this to the primary model because not every account has a Haiku deployment. To use Haiku for background tasks, set `ANTHROPIC_DEFAULT_HAIKU_MODEL` to a Haiku deployment that is available in your account, as shown above.¶
¶
For current and legacy model IDs, see [Models overview](https://platform.claude.com/docs/en/about-claude/models/overview). See [Model configuration](/en/model-config#pin-models-for-third-party-deployments) for the full list of environment variables.¶
¶
[Prompt caching](https://platform.claude.com/docs/en/build-with-claude/prompt-caching) is enabled automatically. To request a 1-hour cache TTL instead of the 5-minute default, set the following variable; cache writes with a 1-hour TTL are billed at a higher rate:¶
¶
```bash theme={null}¶
export ENABLE_PROMPT_CACHING_1H=1¶
```¶
¶
## Azure RBAC configuration¶
¶
The `Azure AI User` and `Cognitive Services User` default roles include all required permissions for invoking Claude models.¶
¶
For more restrictive permissions, create a custom role with the following:¶
¶
```json theme={null}¶
{¶
"permissions": [¶
{¶
"dataActions": [¶
"Microsoft.CognitiveServices/accounts/providers/*"¶
]¶
}¶
]¶
}¶
```¶
¶
For details, see [Microsoft Foundry RBAC documentation](https://learn.microsoft.com/en-us/azure/ai-foundry/concepts/rbac-azure-ai-foundry).¶
¶
## Troubleshooting¶
¶
If you receive an error "Failed to get token from azureADTokenProvider: ChainedTokenCredential authentication failed":¶
¶
* Configure Entra ID on the environment, or set `ANTHROPIC_FOUNDRY_API_KEY`.¶
