Human-in-the-Loop Approval
Keep the user in control of server-driven prompts.
Why a Human Belongs Here
A server triggering model calls is powerful and risky. So MCP says there should always be a human able to deny a sampling request.
The Client Is the Gatekeeper
The client sits between your server and the model. It can pause every sampling request and ask the user before anything runs.
