Why Does the MS SQL Server Node Only Support SQL Authentication Over Entra ID?

Want to use over 200+ MCP servers inside your coding tools like Cursor?
I was reviewing this article that discusses integrating MS SQL Server and suggests authentication might be possible with Microsoft Entra ID.
However, my SQL node and credential configuration only provide options for SQL Server authentication (username/password), as shown in these screenshots:
Am I overlooking a configuration step, or is Entra ID simply not compatible with the SQL node in n8n?
- n8n version: 1.76.1
- Running n8n via (selfhost cloud:
- Operating system: MacOS

It sounds like you’re mixing up two different sets of credentials. The Microsoft Entra ID (OAuth2) credentials are used to authenticate Microsoft services (such as Dynamics, Excel, Outlook, etc.), while the Microsoft SQL node and its corresponding SQL credentials are designed exclusively for SQL Server authentication via username/password (and related settings).
In short, using Entra ID (OAuth2) authentication isn’t supported for the SQL node. The documentation for Microsoft SQL credentials only supports a SQL database connection, meaning you must use SQL Server authentication. This is expected behavior, so you’re not doing anything “wrong” – it’s just that the two integrations use different authentication methods.
