Query the oscilloscope identification string (*IDN?).
AI agents call scope_identify 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 scope_identify tool retrieves device identification metadata only. This is a non-destructive read operation that returns static device information. Even if an agent misuses it by querying identification repeatedly, there is minimal blast radius—no configuration changes, no data loss, no operations triggered.
From the tool's definition Tool performs a 'Query' operation (*IDN?) to retrieve the oscilloscope identification string with no modification of state or triggering of external operations.
Attacks that exploit this kind of access
Query the oscilloscope identification string (*IDN?). It is categorised as a Read tool in the LeCroy Oscilloscope MCP MCP Server, which means it retrieves data without modifying state.
Register the LeCroy Oscilloscope MCP server in PolicyLayer and add a rule for scope_identify: 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_identify is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the scope_identify 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_identify. 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_identify 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.
scope_identify is one line of LeCroy Oscilloscope's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
