Can I connect Fabric Data Agent With Databricks Genie One as external connection

[RamenBhar]

Hi

I have a fabric semantic model. I have created a fabric data agent (published) on top of the semantic model. Now i have created a unity catalog connection along with service. Is MCP connection is true. I can use this connection in AI playground or genie code to interact with the semantic model data. All is working. Region is uksouth.

But is there any way i can use this connection as data source in genie one? I have checked the documentation but cant see this connection in the more connection list. is this because of the region

Short answer: Not a region issue. Genie One external connections are available in regions where Model Serving is supported, and UKSouth appears supported in your screenshot.

What the docs say:

• Genie One does support custom MCP connections from Unity Catalog via More connections.
• For those connections to appear/usefully work, the workspace needs the Third Party Connectors for Agents preview enabled.

So if you don’t see it in Genie One, the more likely causes are:

1. Preview not enabled in that workspace.
2. Permission / login issue on the UC connection.
3. You may be hitting an older workspace state; Databricks recently fixed an issue that prevented custom MCP servers from being used in Genie One.

So: No, not likely because of UKSouth. Check preview enablement, connection permissions, and workspace version/state first.

Many thanks @Lu_Wang_ENB_DBX .

I have checked all of them. They are all good. Its working with genie code ansld ai playground.

Can you please share the details re your 3rd point. Can you direct me to that thread so that I can check or some details.

The workspace is not too old. I leave created this two months back. I suspected that might be an region issue as the green highlighted note telling me that if workspace created after April 2026 is not supported for custom model serving.

Detail:

• Databricks shipped a June 11, 2026 fix for an issue that prevented custom MCP servers from being used in Genie One.
• Genie One custom/external connections are still Beta and are controlled from the workspace Previews page.

What to check

1. Workspace preview is enabled

   • A workspace admin should go to Workspace > Previews and confirm Third Party Connectors for Agents is enabled.

2. The connection exists and you have access

   • Genie One supports adding a custom MCP connection from Unity Catalog via More connections.
   • After the connection is created, metastore admins and connection owners manage who can use it.

3. You can sign in to it from Genie One

   • In Genie One, click + > More connections > Sign in for that connection.

4. Region is probably not the blocker

   • External connections only require a region where Model Serving is supported.

What to do if it still doesn’t show

• If preview is on and you have connection access, but the connection still does not appear in Genie One, treat it as a workspace/platform issue and open a support ticket referencing the June 11, 2026 “Custom MCP server fix” release note.
• In the ticket, include: workspace URL, region (UK South), connection name, confirmation that it works in AI Playground / Genie Code, and that it is missing only in Genie One.

Ok. Cool many thanks

 I will create a support ticket.

Hi @Lu_Wang_ENB_DBX  - Apologies I forgot to mentioned that I have managed to solve this.

Issue:
I was creating service (MCP Service) under schema. This also creating MCP connection where "

is_mcp_connection=true". This connection was not visible in the Genie One even though the is MCP connection true. On the other hand if you create the connection using UI, there is no such explicit filed which allow you to set is_mcp_connection=true. This is where i was struggling.

Solution:
I realised that the connection need to sit in the metastore level. So I have created a connection using the SQL syntax filling all the required attributes along with "is_mcp_connection=true". This resolved the issue and can now see the connection in Genie One.

Also during this exercise i have also seen that genie code has limited feature in uksouth region. So I have moved to westeurope region and is working fine.

Many thanks for your help.
