Prerequisites

Before configuring Claude Code with Microsoft Foundry, ensure you have:

Setup

1. Provision Microsoft Foundry resource

First, create a Claude resource in Azure:

  1. Navigate to the Microsoft Foundry portal
  2. Create a new resource, noting your resource name
  3. Create deployments for the Claude models:

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:
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. This supports a variety of methods for authenticating local and remote workloads.

On local environments, you commonly may use the Azure CLI:

az login

3. Configure Claude Code

Set the following environment variables to enable Microsoft Foundry:

# 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

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:

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'

For current and legacy model IDs, see Models overview. See Model configuration for the full list of environment variables.

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:

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:

{
  "permissions": [
    {
      "dataActions": [
        "Microsoft.CognitiveServices/accounts/providers/*"
      ]
    }
  ]
}

For details, see Microsoft Foundry RBAC documentation.

Troubleshooting

If you receive an error "Failed to get token from azureADTokenProvider: ChainedTokenCredential authentication failed":
