Most of us have used AI chatbots—ask “What’s the weather?” and they tell you. But what if you want AI to actually do something for you, like save a file or add a calendar event? Today’s post explains why AI needs a standard way to connect to tools, and how MCP (Model Context Protocol) makes it simple.
How AI Chat Works Today
When you type a question into an AI chat, here’s what happens:
You send a request, for example “What’s the weather today?”
The AI’s brain (a Large Language Model, or LLM) reads your text and checks its own stored knowledge.
It replies with an answer, like “It’s 28 °C and sunny.”
That back-and-forth is great for chatting, but it can’t reach out to your own apps or files on its own.
Why AI Needs Tool Access
Imagine asking AI to:
- “Add a dentist appointment at 3 PM tomorrow to my calendar.”
- “Email today’s meeting notes to the team.”
AI doesn’t automatically have access to your calendar, your Drive, or your email. To make it work right now, a developer must build a custom “plugin” or connector for each service. Want Slack integration? Write another connector. Want GitHub? Yet another one. Pretty soon, you’ll have dozens of special plugins—just like carrying many different phone chargers.
The Charger Problem & USB-C Analogy
Think about phone chargers: years ago, every device had its own plug, and you needed a different cable for each gadget. USB-C changed all that by giving us one standard plug that fits nearly everything.
MCP does the same for AI. It’s the “USB-C” of AI tools: one universal connector that AI can use to talk to any app—calendar, Drive, mail, databases, and more.
A Simple Example: Saving to Google Drive
Let’s say you ask your AI assistant:
“Save this conversation as conversation.txt on my Google Drive.”
- Without MCP, the AI has no built-in way to talk to Drive. Developers must write a special connector just for Google Drive. To add Dropbox tomorrow? Another connector. It gets messy fast—like needing a different charger for each device.
- With MCP, the AI calls one MCP Server—a one-stop connector that already knows how to talk to Drive. MCP handles all the login, the file format, the upload, and any errors behind the scenes. Your file appears in Drive instantly. And the same MCP setup works for any other tool you need.
Key Benefits of MCP
Simplicity
One connector for every tool. No more dozens of custom plugins.Speed
Add or swap services in minutes, not weeks of coding.Power
AI can chain tasks—fetch data, analyze it, then save results—all in one go.Security
MCP uses standard checks so AI can only do what you’ve allowed it to do.
