measure_amplitude
AI agents call measure_amplitude to retrieve information from PicoScope MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name implies a passive measurement operation that reads amplitude data from the oscilloscope without modifying device state. Given the server context (signal acquisition and measurement), this is most likely a read operation. However, confidence is lowered due to the empty description.
From the tool's definition Tool name 'measure_amplitude' suggests reading/measuring a signal amplitude value from the oscilloscope; description is empty and uninformative.
Attacks that exploit this kind of access
measure_amplitude. It is categorised as a Read tool in the PicoScope MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PicoScope MCP Server MCP server in PolicyLayer and add a rule for measure_amplitude: 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 PicoScope MCP Server. Nothing to install.
measure_amplitude 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 measure_amplitude 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 measure_amplitude. 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.
measure_amplitude is provided by the PicoScope MCP Server MCP server (markuskreitzer/picoscope_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
