📘Introduction

Welcome to this MCP tutorial! In this guide, we’ll walk step-by-step through the Transport Layer in Model Context Protocol (MCP) architecture. By the end, you’ll understand how the transport layer facilitates efficient and reliable communication between clients and servers.

💡What is the Transport Layer?

In the Model Context Protocol (MCP), the Transport Layer is responsible for carrying messages between clients and servers, handling connections, framing, and secure delivery. Specifically, MCP uses JSON-RPC to encode messages, allowing a standardized, model-agnostic format for communication.

🚛 Standard Transport Methods

Model Context Protocol (MCP) defines two standard transport mechanisms for client-server communication: STDIO and Streamable HTTP.

1️⃣ STDIO

STDIO (standard input/output) transport allows clients and servers to communicate directly through input and output streams.
