kwin_reconfigure · Sysprobe MCP: Risk & Policy

WHAT IT DOES

What kwin_reconfigure does on Sysprobe

AI agents invoke kwin_reconfigure to trigger actions in Sysprobe. 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 kwin_reconfigure needs a policy

This tool triggers an external operation on the KWin window manager, causing it to reload its configuration. This is an Execute-category action as it initiates a system-level operation with effects that depend on the current KWin configuration state. It's not purely destructive (no data deleted) nor a simple write, but it does trigger a real system action with potential side effects on the desktop environment.

Verdict

kwin_reconfigure Rate-limited

kwin_reconfigure stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
