execute_sql · Fabric Dw Mcp Cli MCP: Risk & Policy

WHAT IT DOES

What execute_sql does on Fabric Dw Mcp Cli

AI agents invoke execute_sql to trigger actions in Fabric Dw Mcp Cli. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why execute_sql needs a policy

A tool that executes SQL commands can trigger queries, stored procedures, or other database operations whose effects are entirely argument-dependent. SQL execution is classified as Execute rather than Destructive because while the tool CAN execute DELETE/DROP statements, its primary purpose is query execution; the destructive capacity depends on what SQL the agent submits.

From the tool's definition Tool named 'execute_sql' with empty description; in context of a Data Warehouse administration server (fabric-dw-mcp-cli), execute_sql almost certainly runs arbitrary SQL queries against Fabric Data Warehouses and SQL Analytics Endpoints.
