🤖 Model Context Protocol (MCP)

Overview

The Model Context Protocol (MCP) is an open standard that enables Artificial Intelligence (AI) models to securely communicate with external tools, applications, databases, APIs, and services through a standardized interface. It allows Large Language Models (LLMs) to access real-time information, execute functions, and interact with external systems beyond their built-in knowledge.

MCP separates AI reasoning from tool execution by providing a consistent protocol for exposing capabilities such as tools, resources, and prompts. This makes AI applications more modular, reusable, and easier to integrate with different services.
