measure

Take a measurement on a channel. Common parameters: PKPK (peak-to-peak), FREQ (frequency), RMS, MEAN, RISE (rise time), FALL (fall time), DUTY (duty cycle), ALL (all measurements). Installs the measurement on the scope and returns the value.

What measure does on Siglent Sds

AI agents call measure to retrieve information from Siglent Sds without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why measure needs a policy

The tool reads signal measurements from the oscilloscope and returns values. Although it 'installs the measurement on the scope' (a minor instrument configuration side effect), its primary purpose is to retrieve measurement data. No data is created, modified, or destroyed on any system; the oscilloscope display configuration is a negligible, reversible side effect.

From the tool's definition 'Take a measurement on a channel' and 'returns the value' — this queries instrument data (PKPK, FREQ, RMS, MEAN, etc.) from the oscilloscope

Questions about measure

What does the measure tool do? +

Take a measurement on a channel. Common parameters: PKPK (peak-to-peak), FREQ (frequency), RMS, MEAN, RISE (rise time), FALL (fall time), DUTY (duty cycle), ALL (all measurements). Installs the measurement on the scope and returns the value. It is categorised as a Read tool in the Siglent Sds MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on measure? +

Register the Siglent Sds MCP server in PolicyLayer and add a rule for measure: 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 Siglent Sds. Nothing to install.

What risk level is measure? +

measure is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit measure? +

Yes. Add a rate_limit block to the measure 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 measure completely? +

Set action: deny in the PolicyLayer policy for measure. 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 measure? +

measure is provided by the Siglent Sds MCP server (magnusjohansson/siglent-sds-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
