Anthropic's Model Context Protocol (MCP): Origins, Functionality, and Impact
Anthropic's Model Context Protocol (MCP), introduced in late 2024, is presented as an open standard aiming to revolutionize how AI models interact with external data and tools. The MCP provides a unified interface, likened to a "USB port" for AI, enabling models to access diverse resources without custom integrations for each. This new protocol features a client-server architecture with hosts, clients, and servers communicating via structured messages, utilizing primitives like Prompts, Resources, and Tools. The development of MCP was motivated by the need to overcome the isolation of AI models and streamline the integration process, fostering a more collaborative and efficient ecosystem for building context-aware AI applications across various domains like enterprise, software development, and personal productivity.
