SkippyMCP

An MCP server that drives a Rigol MSO/DSO oscilloscope over SCPI/PyVISA, letting an AI assistant configure the scope, run captures, and read measurements. This repo is a small monorepo: SkippyMCP is the project — the stimulus generator and the shared contract below exist to exercise and validate it.

Package

What it is

Runs on

skippy-mcp

SkippyMCP — Rigol oscilloscope control (SCPI/PyVISA)

a network client of the scope

stimpy-mcp

StimpyMCP — GPIO digital-stimulus generator (pigpio); a general-purpose pattern source whose job here is to feed SkippyMCP's logic-analyzer path

a Raspberry Pi

rig-contract

Shared pin map + pattern vector (no hardware deps)

imported by both

rig-contract is the single source of truth tying the two together: StimpyMCP drives the pattern out of the Pi's GPIO, and SkippyMCP asserts the captured logic words against the same rig_contract.PATTERN — a closed loop.

Scope: SkippyMCP is the headline server. StimpyMCP is subordinate test tooling — a pattern generator that earns its keep by exercising Skippy; if it ever grows beyond that role it will fork to its own project.

Develop

python3 -m venv .venv
.venv/bin/pip install -e packages/rig-contract
.venv/bin/pip install -e "packages/stimpy-mcp[dev]"
.venv/bin/pip install -e "packages/skippy-mcp[dev]"

# Per-package checks (mirror CI). The server suites need no hardware — StimpyMCP
# runs on an in-memory simulator, SkippyMCP on a simulated transport:
cd packages/stimpy-mcp        # or rig-contract, or skippy-mcp
../../.venv/bin/python -m pytest -q
../../.venv/bin/ruff check src tests
../../.venv/bin/mypy
