AI智能体协议全面综述：从碎片化到互联互通的智能体网络

Core Viewpoint - The article discusses the evolution and categorization of AI agent protocols, emphasizing the need for standardized communication to enhance collaboration and problem-solving capabilities among AI agents across various industries [1][9]. Summary by Sections AI Agent Protocols Overview - The report introduces a systematic two-dimensional classification framework for existing AI agent protocols, distinguishing between context-oriented protocols and inter-agent protocols, as well as general-purpose and domain-specific protocols [1]. Model Context Protocol (MCP) - MCP represents a centralized approach where a core "MCP travel client" agent coordinates all external services, leading to a star-shaped information flow. While it is simple and easy to control, it lacks flexibility and scalability, making it challenging to adapt to complex tasks [2][3]. Agent-to-Agent Protocol (A2A) - A2A promotes a distributed and collaborative model, allowing agents to communicate directly without a central coordinator. This flexibility supports dynamic responses to changing needs but may face challenges when crossing organizational boundaries [4][5]. Agent Network Protocol (ANP) - ANP standardizes cross-domain interactions, enabling agents from different organizations to collaborate effectively. It formalizes the request and response process, making it suitable for diverse and secure environments [6]. Agora Protocol - Agora focuses on translating user natural language requests into standardized protocols for execution by specialized agents. This three-stage process enhances adaptability and allows agents to concentrate on their core functions [7][8]. Future Trends in AI Agent Protocols - The development of AI agent protocols is expected to evolve towards more adaptive, privacy-focused, and modular systems. Short-term goals include establishing unified evaluation frameworks and enhancing privacy protection mechanisms [9][10]. - Mid-term trends may involve embedding protocol knowledge into large language models and developing layered protocol architectures to improve interoperability [11][12]. - Long-term aspirations include creating a collective intelligence infrastructure and specialized data networks to facilitate structured, intent-driven information exchange among agents [13][14][15]. Conclusion - The exploration of AI agent protocols indicates a clear trajectory towards a more intelligent, autonomous, and collaborative future, with significant implications for technology, society, and economic models [16][17].
