What is the Model Context Protocol (MCP)?

Model Context Protocol (MCP) Server Engineering

Introduction to MCP

Welcome to the future of AI connectivity. The Model Context Protocol (MCP) is an open standard that allows AI models to safely interact with local data sources and remote tools.

Why MCP matters in 2026?

Historically, connecting an LLM to your data required custom, brittle code. MCP provides a standardized interface.

Core Philosophy

  1. Standardization: One protocol for all AI clients (Claude, GPT, local models).
  2. Security: Local control over what the AI can see and do.
  3. Extensibility: Easily add new capabilities (Tools and Resources).

Assignment: Look at the MCP official documentation briefly to identify the three main components: Hosts, Clients, and Servers.
