WHAT IT DOES

What add does on Windows Operations MCP

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

WHY IT NEEDS A POLICY

Why add needs a policy

Without an explicit description, the name 'add' combined with the server's focus on Windows administration and file operations most likely indicates a tool that creates or adds resources (files, users, or configurations) reversibly. This falls under Write category. Severity is high because on a Windows system, unchecked addition of users, files, or configurations could compromise security or system integrity.

From the tool's definition Tool named 'add' on Windows Operations MCP server that enables 'Windows system management' including 'file operations' and administration tasks.
