FAQ from Claude Integration with MCP for Microsoft Graph API

What credentials are required to set up the integration?

You need an Azure AD tenant ID, client ID, and client secret from the Azure Portal, plus an Anthropic API key. These are configured in the respective .env files.

How can I test the MCP server after setup?

Use the provided test-client.js script in the mcp-server directory, or send a curl request to http://localhost:3000/api/graph with the appropriate headers and JSON body.

Is the `consistencyLevel` parameter supported?

The consistencyLevel parameter is generally not supported in many Graph API configurations and has been removed from all default requests. You can manually add it to queryParams if needed, but test carefully.

What security considerations are covered?

The MCP server uses Azure AD authentication, and the Claude application should implement proper authentication. Role-based access control, data retention policies, and audit logging are recommended for sensitive operations.

How do I troubleshoot JSON parsing errors?

Ensure requests use valid JSON with double quotes for keys and string values. Do not nest JSON strings improperly or use single quotes. Check the request format in test-client.js for examples.
