What is MCP and Why Java Developers Should Care

What is MCP and Why Java Developers Should Care Every AI tutorial shows you how to build a chatbot. You give it a system prompt, connect it to an LLM, and it talks back. But the moment you need the AI to do something real, like check inventory or query a payment status, you're writing custom HTTP clients and glue code. MCP (Model Context Protocol) fixes this. It's a standard protocol that lets AI agents discover and call external tools over HTTP. Think of it as USB for AI: one plug, any device.
