Hi there,

I've got a copilot studio agent, adding a "Data Agent MCP Server" as a tool to connect to a Fabric data agent. The connection required by the tool is connected as shown, but...

When testing the MCP connection to return data from the Fabric data agent, I get a 400 error.

Error Message: The connector 'Fabric data agent' returned an HTTP error with code 400. Inner Error: The request URI is not in the expected format Error Code: ConnectorRequestFailure Conversation Id: cb68ed48-97f4-4771-b8ec-e7de5e23af8a Time (UTC): 2025-07-11T20:30:35.696Z

I have no further context, I can't see the URI to even test it separately, and the documentation is vapor. Is there a way to get more information on the error? Or are these known issues with the state of copilot things?

Many thanks,
