What Is MCP?

Model Context Protocol (MCP) is the universal standard for connecting AI models to external tools, databases, and APIs.

Why MCP Matters

Before MCP, every AI tool had its own proprietary way to connect to external services. MCP standardizes this into one protocol that works across Claude, ChatGPT, Gemini, and any LLM.

Think of it like USB for AI — one standard connector that works with everything.

How MCP Servers Work

1. Server exposes tools

An MCP server defines what tools and data it can provide (e.g., "search database", "send email", "read spreadsheet").

2. AI connects via protocol

The AI model connects to the MCP server using a standardized JSON-RPC protocol.

3. AI uses tools naturally

The AI can now use these tools as part of its responses, calling them when needed to complete tasks.
