Hello everyone,

I am trying to connect Claude’s Custom Connector (Remote MCP) to a Databricks Managed MCP Server using a Genie space, but I keep encountering an authentication connection error. I would appreciate guidance on whether this is a configuration issue or a platform limitation.

Environment details:

• Platform: Azure Databricks
• Region: East Asia
• Workspace URL: https://adb-7405618202298753.13.azuredatabricks.net
• MCP Server Type: Managed MCP Server (Genie Space)
• Genie Space ID: 01f11bbc4cc6126eaae20be0e9bdc9cc

MCP Server URL:

https://adb-7405618202298753.13.azuredatabricks.net/api/2.0/mcp/genie/01f11bbc4cc6126eaae20be0e9bdc9...

Steps I completed:

1. Created an Azure Databricks workspace.

2. Created a Genie space called "Sales and Customer Analytics".

3. Assigned a Serverless SQL Warehouse.

4. Verified the Genie space works correctly inside Databricks.

5. Enabled the preview feature: Managed MCP Servers = ON.

6. Verified the MCP server appears under:
   Workspace → Agents → MCP Servers.

7. The MCP server status shows Active, and tools such as query_space and poll_response are available.

OAuth Setup:

I created an OAuth application in the Databricks Account Console:

Account Console → Settings → App Connections → Add connection

Configuration:

Application name: claude-mcp-client

Redirect URLs:
https://claude.ai/api/mcp/auth_callback
https://claude.com/api/mcp/auth_callback

Scopes:
All APIs

Client secret:
Not generated (public client)

Claude Connector Setup:

In Claude:
Settings → Connectors → Add custom connector

I pasted the MCP server URL above.

Error received:

"There was an error connecting to the MCP server. Please check your server URL and make sure your server handles auth correctly."

Additional testing:

Opening the MCP endpoint directly returns:

{
"error_code": 401,
"message": "Credential was not sent or was of an unsupported type for this API."
}

Which appears expected since authentication is required.

However, when I test the OAuth discovery endpoint:

https://adb-7405618202298753.13.azuredatabricks.net/.well-known/oauth-authorization-server

It returns:

HTTP 404

Questions:

1. Does Databricks Managed MCP require the OAuth discovery endpoint for external MCP clients like Claude?

2. Could this be related to my workspace region (East Asia)?

3. Is there a different OAuth discovery endpoint for Azure Databricks MCP servers?

4. Are additional workspace or account-level permissions required for OAuth authentication with MCP?

5. Has anyone successfully connected Claude connectors to a Databricks MCP server in Azure?

Any guidance or troubleshooting suggestions would be greatly appreciated.

Thank you!
