Compute FFT (Fast Fourier Transform) for frequency domain analysis.
AI agents call compute_fft 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.
FFT computation is a purely analytical/mathematical operation performed on already-captured signal data. It reads/processes existing waveform data to produce frequency domain output with no side effects, no data modification, and no external operations triggered.

Compute FFT (Fast Fourier Transform) for frequency domain analysis. 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 compute_fft: 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.
compute_fft 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 compute_fft 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 compute_fft. 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.
compute_fft 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.
