What is MCP?
MCP by Anthropic 2024 standardizes how assistants connect to external tools. Works as universal port: instead of N×M integrations, you have N+M.
How It Works: Client-Server Model
MCP uses a three-part architecture: a host application runs MCP clients that connect to MCP servers. Each server exposes tools, resources, and prompts. Communication uses JSON-RPC over stdio or HTTP.
The Problem It Solves
Before MCP, connecting assistants to data sources required bespoke integration per pair. MCP reduces this to N+M — the same logic that made USB universal.
