Connecting an AI agent to a tool is becoming easier. Letting that agent operate a real business system responsibly is still a different problem.
Imagine an existing commerce system with APIs for reading orders, changing inventory, creating refunds, and disabling staff accounts. OpenAPI can describe the endpoints. A tool protocol can make them discoverable. An agent framework can select an operation and generate arguments.
But those pieces do not, by themselves, answer several business questions:
Which operations may be exposed to an agent-facing surface?
Which invocation must carry a trusted acting subject?
