WHAT IT DOES

What replace_role_privileges does on Dataverse MCP Server

AI agents use replace_role_privileges to create or update resources in Dataverse MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Dataverse MCP Server environment.

WHY IT NEEDS A POLICY

Why replace_role_privileges needs a policy

This tool modifies security role permissions in a system-wide manner. While privileges can technically be restored by reassigning them, the bulk replacement of all privileges in a role is a significant structural change to system access control. It does not irreversibly delete data (thus not Destructive) and does not execute code (thus not Execute), but it is a consequential Write operation.

From the tool's definition Tool description states it 'Completely replaces all existing privileges in a security role with a new set of privileges' and includes a WARNING about removing all current privileges.
