The big one is the confirmation flag — it doesn't match what any binary I have actually accepts, and the behavior around it has flipped between versions, which is a bit scary given it's the flag that controls whether writes to your model get a safety prompt.

We’re evaluating the Microsoft Power BI Modeling MCP Server for enterprise use. The license and documentation indicate it is pre-release/Public Preview software.

However, using the exact same Service Principal token to call **GetSemanticModelSchema** via the MCP succeeds.
