What get_waveform does on Siglent Sds

AI agents call get_waveform 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 get_waveform needs a policy

This tool retrieves and reconstructs waveform data from an oscilloscope without modifying any settings, deleting data, or triggering external operations. It is a read-only query operation with minimal blast radius—the worst outcome is retrieval of sensitive measurement data, but no system state changes or destructive actions are possible.

From the tool's definition Tool name 'get_waveform' and description 'Download waveform data from a channel. Returns voltage and time arrays' indicate pure data retrieval with no modification or side effects.

Questions about get_waveform

What does the get_waveform tool do? +

Download waveform data from a channel. Returns voltage and time arrays reconstructed from the raw oscilloscope data. By default returns up to 1000 points (downsampled from full memory depth). 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 get_waveform? +

Register the Siglent Sds MCP server in PolicyLayer and add a rule for get_waveform: 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 get_waveform? +

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

Can I rate-limit get_waveform? +

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

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

get_waveform 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.
