The Model Context Protocol (MCP) incorporates a Transport Layer as a foundational component, facilitating seamless communication between MCP clients (AI models) and MCP servers (tool providers). This layer is critical for enabling AI assistants to effectively utilize external tools and resources. MCP supports both HTTP and WebSocket protocols for message exchange, providing flexibility in connection types for various use cases. It leverages JSON-RPC 2.0 as its messaging format, standardizing the structure for remote procedure calls. The Transport Layer manages the serialization and deserialization of messages, connection establishment, and reliable data transfer, ensuring AI models can interact with external capabilities robustly.
