Reset the oscilloscope to factory defaults (*RST).
AI agents call scope_reset to permanently remove resources in LeCroy Oscilloscope MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Resetting to factory defaults irreversibly overwrites all current configuration, calibration settings, trigger setups, channel configurations, and any unsaved state. This action cannot be undone and destroys the current working state of the instrument, qualifying it as Destructive with high severity since it would disrupt any ongoing measurements or experiments.

Attacks that exploit this kind of access
Reset the oscilloscope to factory defaults (*RST). It is categorised as a Destructive tool in the LeCroy Oscilloscope MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the LeCroy Oscilloscope MCP server in PolicyLayer and add a rule for scope_reset: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches LeCroy Oscilloscope MCP. Nothing to install.
scope_reset is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the scope_reset rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for scope_reset. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
scope_reset is provided by the LeCroy Oscilloscope MCP server (lucasgerads/lecroy-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
