关于MCP协议最值得看的一篇：起源、架构优势和未来

Core Viewpoint - The MCP (Model Context Protocol) has gained significant attention in the AI field due to the rise of Manus and Agent, with major companies like OpenAI, Microsoft, and Google supporting it, alongside domestic players like Alibaba Cloud and Tencent Cloud launching rapid deployment platforms [1][2]. Group 1: MCP Overview - MCP is designed to facilitate the integration of external services and functionalities into AI applications, acting as a universal interface for communication between AI applications (clients) and various external extensions (MCP servers) [5][6]. - The protocol emphasizes interaction patterns and aims to make AI applications more extensible, akin to a USB-C interface for connecting to an ecosystem [7][8]. - The concept of MCP was inspired by an internal project called LSP (Language Server Protocol), aiming to standardize communication between AI applications and extensions [8][10]. Group 2: Development and Design Principles - The MCP team focused on simplifying the server construction process, allowing for rapid development and iteration using AI-assisted coding [8][12]. - The design principles of MCP include ensuring that tools are controlled by the model rather than the user, allowing for a more seamless integration of functionalities [31][32]. - MCP is not in opposition to open APIs; rather, they are complementary, with each serving different purposes depending on the task at hand [33][34]. Group 3: Future Directions and Innovations - The future of AI applications and agents is expected to lean towards statefulness, which is a topic of ongoing debate within the MCP core team [56]. - There is potential for innovative applications that go beyond simple API wrappers, such as memory MCP servers that allow LLMs to retain information across interactions [34][35]. - The MCP protocol is designed to be flexible, allowing for the integration of various functionalities and the potential for recursive interactions between different MCP servers [50][51]. Group 4: Security and Authorization - The next version of the MCP protocol will include authentication specifications, focusing on user-to-server authorization using OAuth 2.1 or its modern subsets [57][58]. - The design aims to be minimalistic, addressing real pain points without overcomplicating the protocol, ensuring backward compatibility [58][59]. - The protocol's programming language agnosticism allows for a standardized interface, reducing the need for separate SDKs for different programming languages [62].
