WHAT IT DOES

What wait_for_window does on Mcp Control Plane

AI agents invoke wait_for_window to trigger actions in Mcp Control Plane. 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.

RISK

Why wait_for_window is rated High

This tool performs a conditional wait operation that depends on external system state (window visibility/title). While it doesn't directly delete, modify, or move money, it executes a blocking/monitoring action whose effects—halting execution flow until a condition is met—can influence the timing and control flow of automated agent actions.

From the tool's definition Tool 'waits until' a window becomes visible matching a title substring—this is a blocking operation that triggers external application monitoring and conditional logic execution based on window state changes.

RECOMMENDED RULE

The rule that runs wait_for_window safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Control Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For wait_for_window, this is the rule to start with:

wait_for_window Rate-limited

wait_for_window 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.
