Chapter 1

The AI no longer just sits in the chat window

Until recently the AI talked. Now it is allowed to touch things.

Yesterday: you ask, it answers, you paste the result in yourself.
Today: you connect it once — and it does that part too.
MCP is the standard plug for it. USB-C for AI.
Not a product, not a company, nothing to buy — an agreement.
Open to all: Claude, ChatGPT and Gemini use the same plug.

The difference is not the speed. The difference is the access.

One plug, many models

That is the whole trick of MCP: not every AI needs its own connection to your website. There is one agreement they all keep.

Implement the agreement once and you can change the model without starting again. That is precisely why the standard spread so quickly — it saves work for everyone involved.
