Show which Power BI authentication mode is configured without exposing tokens.

Start delegated user device-code login for Power BI REST API. Use only for one-time local setup; service principal is recommended for production.

Poll Microsoft for the pending device-code login and cache the token when authorization is complete.

List all Fabric/Power BI workspaces visible to the authenticated account through the Power BI REST API. Use this first when the user does not provide a workspace name or id.

List semantic models in My workspace or in a specific workspace by id. Use list_workspaces first to resolve workspace ids. If workspace discovery is not authenticated and the user did not name a workspace, ask the user which workspace to use.

Return all visible workspaces and semantic models via Power BI REST API. This is the preferred tool for open-ended questions such as 'which model should I use?' or 'what workspaces can I access?'.

Use Microsoft powerbi-modeling-mcp/XMLA auth to list semantic models inside a known workspace name. This is a fallback when REST workspace discovery auth is unavailable. The workspace name must be explicit; if it is missing, ask the user instead of guessing.
