The MCP Architectural Roles
Abstract
At its most basic level, a protocol is a contract. It's a common agreement that lets different systems talk to each other well. To really understand the Model Context Protocol, though, we need to go beyond the specification document and consider it a living, changing system. The Host, Client, and Server are the system's three main parts, each with a vital role, as shown in Figure 4-1.
