measure_rise_time
AI agents call measure_rise_time 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.
Based on the tool name and server context (PicoScope oscilloscope interface), 'measure_rise_time' likely computes a rise time measurement from already-captured waveform data, which is a read/analysis operation with no side effects. However, confidence is reduced significantly due to the empty description. Severity is low as oscilloscope measurements are typically non-destructive read operations.
From the tool's definition Tool name 'measure_rise_time' suggests a measurement/analysis operation on oscilloscope data. Description is empty and uninformative.
Attacks that exploit this kind of access
measure_rise_time. 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_rise_time: 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_rise_time 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_rise_time 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_rise_time. 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_rise_time 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.
