stop_burst · So Dsc MCP: Risk & Policy

WHAT IT DOES

What stop_burst does on So Dsc

AI agents invoke stop_burst to trigger actions in So Dsc. 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 stop_burst needs a policy

This tool executes a command that interrupts an in-flight camera operation (burst shooting). While not destructive—burst photos are preserved—it does control external hardware behavior and interrupt a running process. This is Execute rather than Write because it triggers an action on a remote device whose effect (stopping vs continuing burst) depends on timing and current state.

From the tool's definition Tool name 'stop_burst' stops an ongoing burst shooting operation on a remote camera. The description indicates it terminates an active camera action and returns postview URLs as a result.
