# MTConnect Mock Agent

DEV MOCK only. Not prod. Local MTConnect agent + built-in VMC-3Axis simulator producing LIVE CHANGING data. For testing the MTConnect protocol driver.

Image: `ladder99/agent:latest` (C++ cppagent + simulator adapter on :7878).

## Commands

```bash
docker compose up -d          # start agent (detached)
docker compose down           # stop + remove
docker compose logs -f agent  # follow logs
```

Agent serves on http://localhost:5000

## Verify

```bash
curl http://localhost:5000/probe     # device model (MTConnectDevices XML)
curl http://localhost:5000/current   # latest value per data item (MTConnectStreams XML)
curl http://localhost:5000/sample     # historical observations from buffer (MTConnectStreams XML)
```

## Endpoints

- `/probe`   — static device model. Devices, Components, DataItems. Device `VMC-3Axis`.
- `/current` — snapshot: newest value + timestamp per DataItem. Poll repeatedly -> values change (Xact/Yact positions, SpindleSpeed, Execution, Line, Block).
- `/sample`  — stream of observations from ring buffer. Params: `?from=<seq>&count=<n>&path=<xpath>`.

## Proof live

Two `/current` calls ~3s apart: `Position Xact` 0.8996 -> -0.2139, `Yact` -1.1855 -> -1.4569, `Line` 263 -> 271. Simulator runs an NC program on loop.
