mtconnect-tap
Read-only CNC machine-tool telemetry via the ot-aiops MCP server. MTConnect is read-only by specification (HTTP REST + XML). Preview — validated against static XML fixtures, NOT a live agent.
When to use
- A machine tool exposing an MTConnect agent (
agent_url, e.g.http://host:5000). - Discover the device model, read current/sample values, OEE inputs, assets.
When NOT to use (routing)
- OPC-UA →
opcua-tap; Modbus →modbus-tap; Siemens →s7-tap; Mitsubishi →mc-tap; MQTT/UNS →sparkplug-tap; cross-protocol triage →industrial-diagnostics. IT/network/Kubernetes/hypervisor/backup → not this tool.
Tools (all read-only)
| Tool | Params | Returns |
|---|---|---|
mtconnect_probe |
endpoint? |
{devices:[{name,uuid,components:[{component,data_items:[{id,type,category,units}]}]}]} |
mtconnect_current |
endpoint? |
{observations:[{data_item_id,type,name,timestamp,value}]} |
mtconnect_sample |
endpoint?, count=100 |
{observation_count, observations:[...]} (bounded) |
mtconnect_assets |
endpoint? |
{assets:[{asset_type,asset_id,timestamp}]} |
mtconnect_oee_snapshot |
endpoint? |
{availability, execution, controller_mode, program, available, running, verdict} |
Call mtconnect_probe first to learn dataItem ids/types, then read values.
Example
mtconnect_oee_snapshot(endpoint="vmc1") →
{"availability":"AVAILABLE","execution":"ACTIVE","program":"O1234","verdict":"running"}
Setup
ot-aiops init (mtconnect: agent_url) · ot-aiops doctor · ot-aiops mcp. Test
against the public MTConnect demo agent. mtconnect_oee_snapshot surfaces OEE
inputs — full OEE % needs planned-time + ideal-cycle context the standard does
not expose. 缺功能提 issue/PR 欢迎留言.
