WHAT IT DOES

What powerbi_capabilities_set does on Power BI MCP Server

WHY IT NEEDS A POLICY

Why powerbi_capabilities_set needs a policy

This tool creates or modifies configuration by enabling/disabling a set of capabilities. The action is reversible (capabilities can be re-enabled later), placing it in Write rather than Destructive. However, disabling capabilities could block critical operations if misconfigured, warranting medium severity. The incomplete description limits confidence slightly.

From the tool's definition 'Enable exactly the provided list (all others disabled)' — modifies capability configuration state irreversibly within the Power BI workspace
