Tool — Fabric IQ (preview)
Connect an agent to Microsoft Fabric data — Ontology, Fabric data agents, and Power BI semantic models — through Fabric IQ. The agent delegates natural-language questions; Fabric IQ runs them against the enterprise ontology (NL2Ontology) and returns synthesized answers under the signed-in user's Fabric permissions.

Requirements
- Microsoft Fabric license for both the developer and every calling end-user.
- For Ontology / Power BI: Entra app with delegated Power BI permissions
Item.Execute.All+Item.Read.All; tenant admin consent required. For Data Agent:DataAgent.Execute.All. - Each Fabric item must be published before it can be consumed through Fabric IQ.
- VNet integration is not supported.
- Tip: for Power BI semantic models, use latest models — measure/hierarchy reasoning benefits significantly.
