jump_to_pattern · Flai MCP: Risk & Policy

WHAT IT DOES

What jump_to_pattern does on Flai

AI agents invoke jump_to_pattern to trigger actions in Flai. 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 jump_to_pattern needs a policy

This tool performs a navigation/UI action in FL Studio by switching the active pattern in the Piano Roll. It doesn't read data, write/create content, or destroy anything — it executes an external operation (changing application state) whose effect depends on the target pattern argument. Severity is low as it only changes UI focus with no data loss risk.

From the tool's definition 'Navigate to a pattern (makes it the active pattern in the Piano Roll)' — triggers an action in FL Studio that changes the active state/focus of the application
