What is MCP
A hands-on book: connect your AI like plugging in a fan.
Your AI is like a very clever helper.
But right now, it cannot touch your other apps.
It needs a wire to connect.
The hard way
Imagine you buy a new fan with no plug.
You must call an electrician to wire it into the wall.
That costs time and money.
For apps, the electrician is a computer programmer. This hard way is called an "API".
The easy way
Now imagine the fan already has a plug.
You just push it into the wall. Done!
For apps, this plug is called "MCP".
One plug for everything
Your phone charger today is Type-C.
The same cable charges many phones.
MCP is like Type-C for AI. One plug fits many apps.
Before you pay for any app
Buying an app for your shop, accounts or bank?
First ask one question: "Does it have MCP?"
If yes, your AI can help you with it.
How to check
Open Google.
Type the app's name, then the word "MCP".
If you see it, good. It has the plug.
No plug? Use an adapter
Like travelling overseas, you can use an adapter.
Zapier is an adapter for apps. It is free for small use.
Still nothing?
No plug, no adapter?
Don't worry. Your AI can still use the website for you, like a person clicking and typing.
That is our next book.
Stay safe
Only plug in apps you trust.
Never give your bank password to anyone, not even your AI.
