WHAT IT DOES

What scope_setup_measurements does on LeCroy Oscilloscope MCP

AI agents use scope_setup_measurements 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_setup_measurements needs a policy

The tool name suggests it configures or sets up measurement parameters on the oscilloscope. Based on the naming convention of sibling tools (scope_configure_channel, scope_configure_trigger), this likely writes/modifies measurement settings on the device. Empty description lowers confidence. Classified as Write since it configures settings rather than destroying data or executing code.

From the tool's definition Tool name 'scope_setup_measurements' and empty description; sibling tools include scope_configure_channel, scope_configure_trigger suggesting configuration/write operations

Verdict

scope_setup_measurements Rate-limited

scope_setup_measurements 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.

FAQ

Questions about scope_setup_measurements

What does the scope_setup_measurements tool do? +

scope_setup_measurements. It is categorised as a Write tool in the LeCroy Oscilloscope MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on scope_setup_measurements? +

Register the LeCroy Oscilloscope MCP server in PolicyLayer and add a rule for scope_setup_measurements: 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.

What risk level is scope_setup_measurements? +

scope_setup_measurements is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit scope_setup_measurements? +

Yes. Add a rate_limit block to the scope_setup_measurements 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.

How do I block scope_setup_measurements completely? +

Set action: deny in the PolicyLayer policy for scope_setup_measurements. 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.

What MCP server provides scope_setup_measurements? +

scope_setup_measurements 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.
