1. What is MCP Architecture?

MCP architecture is the structure that defines:

→ How AI models, tools, and users communicate

→How context is passed and preserved

→How standardized requests and responses work

✓Imagine It’s like the blueprint of how a smart AI ecosystem runs, keeping everything connected and consistent.

2. Core Layers of MCP Architecture

There are three major layers in MCP:

Layer Role

Client Layer

The user or front-end app that sends a request

Server Layer

The MCP Server that manages context, tools,
