Get all Fabric/Power BI workspaces
AI agents call get_workspaces to retrieve information from Microsoft Fabric MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a list of workspaces without creating, modifying, deleting, or executing any operations. It is a pure read operation with minimal blast radius—an AI agent listing workspaces poses no risk of data loss, code execution, or financial impact.
From the tool's definition Tool name 'get_workspaces' and description 'Get all Fabric/Power BI workspaces' indicate a query/retrieval operation with no data modification or side effects.

get_workspaces is provided by the Microsoft Fabric MCP Server MCP server (snahrup/microsoft-fabric-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_workspaces is one line of Microsoft Fabric MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
