window_move · It2 MCP: Risk & Policy

WHAT IT DOES

What window_move does on It2mcp

AI agents use window_move to create or update resources in It2mcp — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your It2mcp environment.

WHY IT NEEDS A POLICY

Why window_move needs a policy

This tool repositions a window on screen, which is a reversible UI state change. It modifies the window's position but does not execute commands, delete data, or have financial implications. The blast radius is low — worst case is a misplaced window that can be moved back.

Verdict

window_move Rate-limited

window_move stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
