Core Viewpoint - The emergence of MCP (Model Context Protocol) is seen as a pivotal development in the AI industry, akin to the rise of mobile apps in 2010, enabling more efficient interactions between large models and external tools [1][2]. Group 1: Definition and Importance of MCP - MCP is an open standard that allows large models to interact with external data sources and tools, similar to a universal interface like USB [6][12]. - The adoption of MCP is expected to lead to a significant explosion in AI applications by 2025, as it simplifies the development process for AI applications [5][12]. Group 2: Current Trends and Adoption - Since February 2024, a global wave of MCP adoption has occurred, with major companies like OpenAI, Google, and others announcing support for the protocol [2][16]. - Over 4,000 MCP servers have been launched globally, indicating rapid growth in the ecosystem [12]. Group 3: Developer Experience and Challenges - Prior to MCP, developers faced high barriers in integrating external tools with large models, often requiring extensive coding and adaptation [10][11]. - With MCP, developers can focus on maintaining their applications rather than managing external tool performance, significantly reducing development workload [12][13]. Group 4: Competitive Landscape and Strategic Shifts - The shift towards MCP represents a strategic pivot for major AI companies, moving from isolated development to a more collaborative ecosystem [17][21]. - OpenAI's previous closed strategy has been contrasted with MCP's open approach, highlighting the advantages of a more inclusive development environment [18][21].
