account settings in claude

To open and configure Claude with Microsoft Foundry, use the product’s own configuration flows rather than Windows account settings.

For Claude Code (CLI and VS Code extension):

1. Ensure Claude Code is installed and configured for Microsoft Foundry.
2. To validate configuration and see current settings, open a terminal in a project folder and run:

      claude
   

3. At the Claude prompt, run:

      /status
   

   This shows key settings such as:
   • API provider (should be Microsoft Foundry)
   • Foundry resource name
   • Default model (for example, claude-sonnet-4-6)
4. If there are errors like authorization failures or missing models, use the troubleshooting guidance:
   • For 401/403, run az login again or verify the ANTHROPIC_FOUNDRY_API_KEY value.
   • If models are not found, confirm ANTHROPIC_FOUNDRY_RESOURCE and any ANTHROPIC_DEFAULT_*_MODEL values match the deployment names.
   • If Claude prompts for Anthropic login instead of Foundry, ensure CLAUDE_CODE_USE_FOUNDRY=1 is set before starting Claude.

For Claude Code VS Code extension settings:

1. In VS Code, open Settings (Ctrl+, or Cmd+,).
2. Search for Claude Code: Environment Variables.
3. Select Edit in settings.json and configure:

      {
        "Claude Code: Environment Variables": {
          "CLAUDE_CODE_USE_FOUNDRY": "1",
          "ANTHROPIC_FOUNDRY_RESOURCE": "<your-resource-name>",
          "ANTHROPIC_FOUNDRY_API_KEY": "<optional-for-non-entra-auth>"
        }
      }
   

4. Restart VS Code (preferably launched from a terminal where the environment variables are set) and open the Claude Code panel via the spark icon in the sidebar.

For Claude Desktop with Microsoft Foundry:

1. Open Claude Desktop.
2. Go to Help > Troubleshooting > Enable Developer Mode.
3. Then go to Developer > Configure third-party inference.
4. In the configuration window:
   • Select Connection.
   • Choose Foundry as the inference provider.
   • Enter the Foundry resource name and API key.
   • Add the Foundry model deployment names (first in the list becomes the default model).
5. Select Apply locally; Claude Desktop restarts in 3P mode.
6. On the sign-in screen, choose Start in Cowork on 3P to use Claude with the Foundry deployment.

If settings still do not open or work as expected, verify prerequisites:

• A supported paid Azure subscription type.
• Access to Microsoft Foundry and a Foundry resource with Claude models deployed.
• A valid Foundry project API key when using API-key-based configuration.
