Get list of PowerBI workspaces
AI agents call get_workspaces to retrieve information from PowerBI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of workspaces without creating, modifying, deleting, or executing any operations. It is a straightforward read operation with minimal risk; the information returned is typically metadata about organizational resources that an authorized user would be able to access.
From the tool's definition Tool name is 'get_workspaces' and description states 'Get list of PowerBI workspaces' — both indicate a retrieval operation with no modification.
