What Is MCP? How the Model Context Protocol Connects AI to Tools and Data

A lot of companies are adding "​MCP's​" to their services.

It means "Model Context Protocol" but really it should just be called a "connector."

It means you can use ChatGPT or whatever AI to ask questions about all your data inside a service:

For example the email company ​Kit​ (which I'm using to send out this email right now) has an MCP, so I connected it to ChatGPT and now I can ask questions and it'll give me the answer, like this:

And it made me a helpful chart....which I INSTANTLY saw some mega dips in open rate.

I then promoted it to ask why these major dips happened, and it found that it was from including certain types of links that TANKED email deliverability (for example YouTube shortened links vs full links):

Another MCP I've been using with ChatGPT is ​Ahrefs​ (popular keyword research tool I use all the time) and now instead of sifting through complex reports, I can just have ChatGPT do all the work, like this:

Then it pretty much told me what to title and slug my post:

Anyways, this MCP stuff is exciting because more and more companies are allowing you to connect to their services with your AI, so you can do stuff in it quickly.

Imaging instead of logging into Google Calendar you can just tell ChatGPT "Schedule a meeting with John at 11am on Friday about the product" and it'll just do it for you.
