scope_auto_setup · LeCroy Oscilloscope MCP: Risk & Policy

WHAT IT DOES

What scope_auto_setup does on LeCroy Oscilloscope MCP

AI agents invoke scope_auto_setup to trigger actions in LeCroy Oscilloscope MCP. 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 scope_auto_setup needs a policy

This tool triggers an automatic configuration operation on a physical oscilloscope, adjusting hardware settings (vertical scale, horizontal scale, and trigger). It executes an external operation with real-world effects on lab equipment. It's not merely reading data, and while it modifies settings, it's an active command execution on a physical device rather than a simple write to a data store.
