🤖 What are MCPs
MCP is a Protocol for adding Context to our Models.
It has many use cases. One of the ones we use the most is being able to query the database without having to deal with complex joins.
For example, if we add the Postgres MCP, we could ask our LLM: "Tell me how many Android users registered yesterday between 12pm and 6pm." The MCP gives the LLM the ability to run queries, so it could look at the database structure and give us the expected result without us writing the mega-query.
But the real power of MCPs is unlocked when we create our own servers, since that way other people can interact with them. For example, if I'm an ecommerce I could allow people to buy my products through ChatGPT or Claude.
But MCP isn't just those tools, it also has Resources and Prompts. The specification is quite large (and inconsistent), which is why we read the entire thing before making the MCP in depth: Build your server following best practices course that we've just published in Codely Pro Premium.
This course is the first we've published exclusively for Premium. This is because it required a huge research effort to prepare so the content would be TOP quality. We hope you enjoy it as much as we enjoyed recording it. 😊
Also, if you want to learn more about MCPs and all their components, we've just published a video on YouTube where we explain it step by step.
✅ How to test MCPs
Here we need your help. We've just published a blog post about how to test MCPs, and we've also shared it on some social media platforms. Could you give us your upvote so the post reaches more people? 🙌
Thanks a million and we hope you enjoy the post. 😊
🤖 Last spots for the AI Workshop!
We're about to fill up the 4th edition of the Workshop on November 4th. If we do a next edition, it'll probably be in December, so grab the last spots!
We already did an alpha edition that went great, and the first one, thanks to the feedback we got, turned out even better! 🙌
By the way... Don't forget that tomorrow at 9am CEST, there's Cafe con Codely! where we'll be discussing the tech news of the week. You can follow it on YouTube or Twitch.
And since you've made it this far in the newsletter, here's the joke of the week, which I know you were waiting for:
> Did you know there's a song that predicted the world's largest AI server farm? It's... Old MacDonald had a farm, A-I, A-I, Ohhhhhhhhhhh! 😂
Cheers!
