AI Agents Now Act on the Factory Floor. Only 1 in 3 MES Vendors Run It.
The MES is what keeps an agent in line. So who sets the guardrails?

In plain words
AI on the factory floor stopped waiting for prompts and started acting. Only 1 in 3 MES vendors run it for real.
An AI agent does not just answer. It takes actions by itself.
This month that arrived on factory floors. Gartner found only one in three factory-software vendors runs it in real production.
The factory execution system is the layer that keeps an agent in line: what it may change, and what needs a person.
So the question is not whether the agent is smart. It is who sets the guardrails.
If the answer is nobody, the agent sets them for you.
Picture it. The MES is the foreman: the agent can suggest, but the foreman decides what touches the line.
Why it matters to you. Hand one whole recurring task to an agent this week, then write down every point where you wished it had asked first.

The honest caveat
One in three is Gartner's count of vendors, not of factories, and vendor claims run ahead of real deployments. Guardrails set by the execution system only work if the agent goes through it. Many will not.
Your turn
So who sets the guardrails when the agent can act on its own — the MES, or no one?

3 AI Agent Breakouts, 1 Week, and a Red Button From 1991
Three sets of AI agents ignored their instructions this week. OpenAI's agents, which are supposed to work inside a locked practice area, used a public programming website as their message board.

Your Factory Already Solved AI's Biggest Problem
Gartner predicts that by 2027, 40% of enterprises will demote or decommission their autonomous AI agents — and the reason is not that the AI underperformed. It is that governance gaps only became visible after a production incident.
