We are having issues when trying to use the Dremio Cloud MCP integration with Claude.
We are following the documentation, step-by-step.
When we get to the final step - Login into dremio for the URL Callback and authorization inside Claude - The login page gets STUCK with no instructions, no errors.
We tried with multiple users and no success.
Can someone help us?
Thanks.

We managed to make it work by enabling and login via Google account.
But when we use a “Dremio” account, the empty screen appears and we can’t proceed.
But the google account was just a test… Is the Dremio account not available for this? In the documentation, nothing was said about this.
This is an expected behavior, as the MCP Authentication uses OAuth, which by design only supports social login methods (Google, GitHub, Microsoft) and configured Enterprise Identity Providers (OKTA, Microsoft Entra ID, generic OIDC, etc.).
If your organization has disabled all social or enterprise identity providers, then the login screen will appear blank because there are no compatible auth methods to display.
To resolve this: Ensure at least one social login method (Google, GitHub, or Microsoft) or an Enterprise IDP is enabled for your organization in Settings > Authentication in the Dremio Cloud admin console.
Thanks for the answer!
Everything became more clear.
I only think that the documentation should show / mark this explicit situation or something.
We were thinking it was a bug because in the docs there was no mention that local users wouldn’t work.
Instead of a blank screen it should show what you said… “there are no compatible auth methods to display.”
Hi @Mauricio_Macri ,
Thank you for confirming this behavior. We appreciate your feedback and will work with our docs team to update the details regarding the supported authentication methods for the MCP (OAuth) authentication flow.
Best Regards,
