Multi-Tube-OD-Reader (my_app.classes.device.Device)

Multi-Tube-OD-Reader (my_app.classes.device.Device), adapted from natlabrockies/multi-tube-od-reader. It reads serial_number, port_positions and port_usage; sets name; runs measure_voltage and blink. measure_voltage: measure a DC or RMS voltage on a declared channel or terminal pair and return the value with its sampling timestamp and measurement range. A hardware driver: the market serves its fake backend, so no instrument is needed.

Install

Three ways to run this device. Each one serves its fake backend: no instrument, no simulator install and no upstream checkout.

OpenAI4S (one command)

shell
openai4s lab add labs/natlabrockies__multi-tube-od-reader

Installs the device into the OpenAI4S Lab on its fake backend and starts it. First time? See setup below.

Or, in the workbench, open the Lab tab → Market → Install.

Standalone MHS endpoint

shell
git clone --depth 1 https://github.com/PKU-YuanGroup/OpenMHS.git && cd OpenMHS
PYTHONPATH=MHS/sdk/src python3 -m mhs serve labs/natlabrockies__multi-tube-od-reader --port 7400
# in a second terminal, from the same directory:
PYTHONPATH=MHS/sdk/src python3 -m mhs describe --endpoint http://127.0.0.1:7400

Serves the device as an MHS endpoint on port 7400 from an OpenMHS clone (Python 3.10 or later, standard library only); describe prints what it offers.

Any MCP host (Claude Desktop, Cursor, …)

mcp configuration
{
  "mcpServers": {
    "multi-tube-od-reader": {
      "command": "python3",
      "args": [
        "-m",
        "mhs",
        "serve",
        "labs/natlabrockies__multi-tube-od-reader",
        "--mcp"
      ],
      "env": {
        "PYTHONPATH": "/path/to/OpenMHS/MHS/sdk/src"
      }
    }
  }
}

Add this server to the host's MCP configuration and replace /path/to/OpenMHS with the path of your OpenMHS clone. The host starts the server and talks to it on stdin and stdout.

What it does

Measures

  • serial_number
  • port_positions
  • port_usage

Adjusts

  • name

Actions

measure_voltage
Measure a DC or RMS voltage on a declared channel or terminal pair and return the value with its sampling timestamp and measurement range.
blink
Blink the device indicator LED through the native Device.blink sequence

Names as the driver declares them. Units, limits and the safety declaration are in the package's REFERENCE.md.

First-time setup

The OpenAI4S workbench with the OpenMHS lab, from a source checkout:

shell
# OpenAI4S workbench with the OpenMHS lab (source checkout)
git clone --recursive https://github.com/PKU-YuanGroup/OpenAI4S.git
cd OpenAI4S && ./setup.sh && source .venv/bin/activate
openai4s lab add labs/natlabrockies__multi-tube-od-reader
openai4s serve        # open the Lab tab

The standalone endpoint and the MCP server need only an OpenMHS clone and Python 3.10 or later. More in the market's getting-started guide and on the OpenAI4S host page.
