Model Context Protocol (MCP)

MCP is a standard protocol that lets AI models connect to external tools, data sources, and services in a structured way.

🧑For teens & curious minds
Model Context Protocol is an open standard (developed by Anthropic) that defines how LLMs communicate with external tools and data sources. It provides a structured interface for context injection, tool calls, and resource access.
💡Visual Analogy

MCP is like USB-C for AI — a universal standard connector that lets any AI plug into any tool or data source cleanly and safely.

Key Terms

Server:An MCP server exposes tools and data to the AI model.
Client:The AI model that connects to MCP servers.
Context:Information passed to the AI to help it understand the task.
