OAuth authentication is required for MCP servers hosted on Databricks Apps

Hi all.

I'm deploying an agent with a custom MCP using Databrikcs.

Unfortunately when I try to test the MCP connectivity I receive this error:

OAuth authentication is required for MCP servers hosted on Databricks Apps. Your current authentication method is not supported. Please use OAuth authentication instead. For more information: https://docs.databricks.com/aws/en/generative-ai/mcp/custom-mcp

I already assigned the CAN USE permission to the app but I still have this error.

Cna you help me with this "stupid" error? Thank you

I found the issue. I missed to create the OAuth token into Identity & user. I was using the SP secret.
