Can you imagine if your favorite chatbot could read your Google Drive files, send messages via Slack, or even modify documents on your computer without you having to do anything? Well, that is exactly what the Model Context Protocol (MCP) makes possible, a little gem of open-source code created by Anthropic, the same folks behind Claude, that other chatbot you’ve probably heard of. Although it went a bit unnoticed when it was announced back in November, now giants like Google, OpenAI, and Microsoft are jumping on the bandwagon.
Until now, every time you wanted an AI model to interact with an external application, you had to build a custom connector. It was like having to invent a new cable every time you wanted to plug something in. But with MCP, that’s over: it works like a universal connector that opens the door to all kinds of integrations. Want the AI to access your calendar? Done. Your GitHub files? Also done. Your PC? Of course!
The key lies in its structure: a bidirectional connection between client and server. For example, if you use the desktop app of Claude, that would be the MCP “client,” which requests the data. The MCP “server” is the one that delivers it, whether from Google Maps, WhatsApp, Windows, or any other system you configure. And since it is open source, anyone —yes, you too— can create their own MCP server for whatever they want. So if you’re a bit of a geek, you can connect your AI to Spotify, your hard drive, or even Telegram.
But be careful, don’t confuse MCP with an AI agent. It is not a brain that thinks or acts on its own, but the wiring that allows it to do so. It’s like the nervous system of a modern AI, giving it access to senses and limbs. And the best part? By integrating with new protocols like Google’s Agent2Agent (A2A), it is paving the way for a new generation of assistants that not only speak nicely but also do real things.
The most useful (and curious) MCP servers you can try right now
Now that we know what the heck MCP is and why every techie is drooling over it, let’s get to the juicy part: the MCP servers that you can already install and use without complicating your life. And be warned, because we’re not just talking about connecting your AI with Google Drive (though that too). There’s everything, from professional tools to platforms you use every day to procrastinate.
Let’s start with the official ones, those that Anthropic has polished with care. The Google Drive MCP Server allows you to search and access your files directly from Claude, without having to open a single tab. Then you have the Filesystem MCP, which gives the AI full access to your computer: it can read, write, move, delete, or create files. Basically, it’s like your digital assistant could stroll through your hard drive like Pedro in his house.
Want something more communicative? The Slack MCP Server allows your AI to send messages, respond in threads, manage channels, and more. Imagine you’re in a meeting and you ask your chatbot to send a summary to the workgroup. Boom, done. Are you a developer? Then you’ll love the GitHub MCP Server: it lets you manipulate repos, create branches, and perform file operations like a boss.
But wait, the community has also been doing its homework. There are servers for almost everything: Google Calendar, Apple Calendar, Excel, Figma, Notion, Gmail, Spotify, Telegram, Discord, and even Airbnb. Yes, you read that right: you can set up an MCP server that connects your AI with your vacation bookings. And how about one for YouTube or X (the former Twitter)? They exist too. And if you’re curious, there’s a complete list of all existing ones on GitHub that is updated frequently.
The reality is that this is just the beginning. Anyone can build their own MCP server to automate tasks, create custom workflows, or just play around. Because with this technology, chatbots stop being charming chatterboxes and become real productivity tools. And the best part: you decide how far the magic goes.
