Machine Control Protocols (MCPs) are structured systems or sets of rules that govern and restrict the actions of machines, particularly AI agents, within digital environments. MCPs define what operations an AI can perform, which resources it can access, and under what circumstances. They are crucial in cybersecurity to prevent unauthorized actions, data breaches, and misuse of computational resources. MCPs can include authentication measures, permission settings, and monitoring mechanisms to ensure compliance with organizational policies. By implementing MCPs, organizations can maintain control over automated systems, reduce risk, and ensure that AI agents act within predefined ethical and operational boundaries.
