Newport Agilis agUC2

Newport Agilis agUC2, adapted from lando1784/pyagilis. It reads x_steps, y_steps, x_at_limit, y_at_limit and 2 more; runs jog, go_to_zero, set_zero and stop_motion. jog: jog axis 1 and axis 2 by signed step counts (relative motion). 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/lando1784__pyagilis

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/lando1784__pyagilis --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": {
    "pyagilis": {
      "command": "python3",
      "args": [
        "-m",
        "mhs",
        "serve",
        "labs/lando1784__pyagilis",
        "--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

  • x_steps
  • y_steps
  • x_at_limit
  • y_at_limit
  • x_last_operation
  • y_last_operation

Adjusts

Nothing declared.

Actions

jog
Jog axis 1 and axis 2 by signed step counts (relative motion)
go_to_zero
Move both axes back to counter zero (the upstream goToZero)
set_zero
Reset both axis counters to zero without moving (the upstream setZero)
stop_motion
Stop both axes (the native stop); the device's safe state

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/lando1784__pyagilis
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.
