Summary

The "Agent Protocol Handbook" outlines the critical role of standardized protocols in the emerging AI agent economy, particularly in 2025 and 2026. It highlights the shift from conversational AI to action-oriented agents, emphasizing the need for robust execution infrastructure. Key protocols discussed include the Model Context Protocol (MCP) for standardizing data and tool access, and the Agent Payments Protocol (AP2) for secure, autonomous transactions. The article positions these protocols, formalized by the Agentic AI Foundation (AAIF), as foundational layers enabling interoperability, security, and economic scale for AI systems. It also introduces Hodman Murad, founder of Asaura AI, who is building an AI for executive function and contributing to the understanding of these new agent protocols.

Key takeaway

For AI Engineers and Data Scientists building agentic systems, understanding and implementing the new agent protocols like MCP and AP2 is essential. These standards provide the necessary infrastructure for agents to access tools, manage data, and conduct secure transactions, ensuring interoperability and future-proofing your AI investments. Focus on integrating these foundational layers to build scalable and auditable autonomous AI solutions.
