MCP Servers

oscilloscope-mcp

AI-driven USB oscilloscope control via FastMCP, enabling waveform capture, CSV export, and frequency measurements on PicoScope, Hantek, or a built-in simulator.

README

oscilloscope-mcp

AI-driven USB oscilloscope control via FastMCP 3.2. Connect screenless PC scopes (PicoScope, Hantek) or run the built-in simulator for dry-runs. Capture waveforms, export CSV, and compute frequency, Vpp, duty cycle, and rise time from your agent.

How it runs

Mode	Hardware	When
Simulator (default)	None	Development, CI, agent dry-runs
PicoScope	PicoScope 2000/3000/5000/6000 USB	Production bench with PicoSDK + pyPicoSDK
Hantek	Hantek 6022BE/BL	Budget USB scope with PyHT6022 + libusb

The MCP server never bundles oscilloscope drivers or PicoSDK. Install vendor software separately, then point the backend at your device.

Hands-in / Hands-out

Direction	Artifacts	Notes
Hands-in	`device_id`, channel config, trigger settings	Via `scope_device`, `scope_configure`, `scope_trigger`
Hands-out	Waveform preview (downsampled JSON)	`scope_capture(operation="single")`
Hands-out	CSV + JSON summary files	`scope_capture(operation="export_csv")` in `OSCILLOSCOPE_MCP_CAPTURE_DIR`
Hands-out	Measurements (Vpp, freq, duty, rise)	`scope_measure(operation="all")`

Fleet pipelines
