Core Concepts

Understand the fundamentals of the Model Context Protocol. From architecture to authentication, these guides explain the key concepts behind MCP.

What is the Model Context Protocol (MCP)?

A comprehensive guide to the Model Context Protocol (MCP) — the open standard created by Anthropic that enables AI models to securely connect with external data sources and tools.

MCP Architecture Explained

A technical deep dive into the Model Context Protocol architecture — hosts, clients, servers, protocol flow, message types, and capability negotiation.

Tools vs Resources vs Prompts in MCP

Understand the three core primitives of the Model Context Protocol — tools, resources, and prompts. Learn when to use each, how they differ, and see practical examples.

MCP Transport Protocols
