What build_and_push_image_to_ecr does on Amazon MQ MCP Server

AI agents invoke build_and_push_image_to_ecr to trigger actions in Amazon MQ MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why build_and_push_image_to_ecr needs a policy

This tool executes code operations (container image build) and performs irreversible uploads to a registry.
