Digilent WaveForms MCP Server
Wraps the Digilent WaveForms SDK to control oscilloscopes, arbitrary waveform generators, and logic analyzers from Claude. Works with Analog Discovery 2/3, Digital Discovery, and any hardware supported by libdwf. You get tools for analog capture with single or continuous modes, waveform generation (sine, square, triangle), voltage measurement, power supply control, logic analyzer capture, GPIO read/write, and SPI transfers. Ships as a Docker container but requires you to build a derived image that adds Digilent's proprietary runtime and SDK yourself since redistribution isn't allowed. Runs privileged for USB device access. Reach for this when you need Claude to drive test equipment or prototype analog/digital circuits interactively.

dwf-mcp-server
MCP Server for Digilent WaveForms
instruments — oscilloscope, arbitrary waveform generator (AWG), and logic analyzer.
Built on dwfpy, a Python binding for the
Digilent WaveForms SDK (libdwf).
Supported Devices
- Analog Discovery 2 (AD2)
- Analog Discovery 3 (AD3)
- Digital Discovery (DD)
- Any device supported by the Digilent WaveForms SDK
Prerequisites
- Docker installed on the host machine.
- No host-side WaveForms SDK installation is required. The proprietary
libdwf.sois added via a derived Dockerfile layer (see Installation). - USB device permissions — Digilent USB devices default to
root:root 0664. If the container cannot find any devices, add a udev rule on the host:
Then reload:# /etc/udev/rules.d/99-digilent.rules SUBSYSTEM=="usb", ATTRS{idVendor}=="1443", MODE="0666"sudo udevadm control --reload-rules && sudo udevadm trigger
