scope_help
AI agents call scope_help to retrieve information from LeCroy Oscilloscope MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name 'scope_help' strongly suggests this tool retrieves help/documentation information, which is a read-only operation with no side effects. However, the empty description lowers confidence. Given the context of an oscilloscope control server, a help tool is almost certainly informational only. Severity is low as misuse would have minimal impact.
From the tool's definition Tool name is 'scope_help'; description is empty or uninformative.
