WHAT IT DOES

What scope_set_math_trace does on LeCroy Oscilloscope MCP

AI agents use scope_set_math_trace to create or update resources in LeCroy Oscilloscope MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your LeCroy Oscilloscope MCP environment.

WHY IT NEEDS A POLICY

Why scope_set_math_trace needs a policy

This tool modifies the display state of a math trace on the oscilloscope (showing or hiding it), which is a reversible configuration change. It does not execute code, delete data, or have financial implications. It is a Write operation since it changes the instrument's configuration state.

Verdict

scope_set_math_trace Rate-limited

scope_set_math_trace stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
