OPC UA to Claude, 0 stars: shift leads ask plain questions about a simulated plant and the server, not the AI, computes the numbers

Halliburton data scientists in JPT: a geosteering agent should propose the next move and an engineer should be able to override it

The authors say real-time AI recommendations that affect the well must work inside a management-of-change framework, with a qualified engineer able to review and override each decision and a full record of actions. Their line: "not autonomous drilling but collaborative intelligence."

Modbus MCP: lets an AI agent read Modbus devices, and it refuses to write unless you switch writes on

Writes stay off unless the server is started with them enabled, and a write is sent once and never retried, so a lost reply comes back as "may have been applied, check first." That is how a tool that can touch a live register should behave.

For controls and instrumentation techs: let an agent pull register values and device IDs for troubleshooting without giving it a way to change anything.

uniwire: electrical single-line diagrams written as code, with an MCP server so an agent can edit and check them

A diagram kept in a text file can be changed by an agent and reviewed line by line like any other change. It maps to CIM, IFC and IEC 61850.

For electrical designers and panel builders: describe sources, breakers, cables and loads in one file and get drawings plus rule checks.
