Welcome to the second article in our Model Context Protocol (MCP) series! In the first article , we covered all the basics—what MCP is, how it works, and its key components. Not only that, we even built our first simple MCP server to put that knowledge into practice. If you’re new to this topic, I highly suggest you check out that first article before continuing here. It’ll give you a clear understanding of what’s going on and make this journey a lot smoother. Now, it’s time to step things up. In this article, we’re going to take what we’ve learned and build something more advanced – a custom MCP server from scratch. This is where things get interesting, because we’ll see just how flexible and powerful MCP can be with the new tooling we’re going to explore, and how we can shape MCP to fit our own needs. Let’s get into it! First, let’s quickly mention the tech stack that we’re going to work with. We’re going to use the same one from the previous article: TypeScript, Node.js and MacOS. If you're using a different tech stack, no worries, the key ideas will be the same. As an additional reference, you can also refer to documentation which includes basics for Python and Java too.

Large Language Models (LLMs) like DeepSeek are powerful tools, but they often come with built-in safety layers and censorship filters. These restrictions might block sensitive topics, controversial opinions, or even accurate historical facts — especially when it comes to politically sensitive regions like China. In our previous article , we explored how to jailbreak Large Language Models (LLMs) like DeepSeek, using prompt engineering and unlock restricted answers. Now, we’re diving into the most powerful and lasting approach: fine-tuning. With tools like LoRA and Unsloth on free platforms like Google Colab, we’ll show you how to tweak DeepSeek to provide accurate, uncensored historical answers about China—free from filters that might obscure the truth. Our goal is to make DeepSeek a reliable source for sensitive topics, where default restrictions can block factual responses. Fine-tuning lets us retrain the model on a custom dataset to soften those limits, and as we’ll see, it’s more accessible than ever with modern tools. Done responsibly, this can reveal what’s hidden without crossing ethical lines.

Learn how to prompt Replit Assistant, an advanced AI-coding assistant, to create your first Slack bot with Bolt, a framework for building Slack apps with Python (or JavaScript).

It’s undeniable that AI has - for better or worse - already had a huge impact on the software industry, from its practical applications at the technology level, to the changing demand from skills and experience, to the layoffs linked to AI processes taking over. One area we haven’t really talked about in our articles yet is recruitment: it’s no secret that AI is being used to scan CVs and automatically filter candidates. Several of my developer friends have been talking about this recently, and with a slew of layoffs in tech sending a lot of IT folks on the hunt for new jobs, I thought this would be the perfect time to dive into how AI is being used to filter candidates, and what you can do to stand out and get past the filters. Forbes estimates that 65% of employers will use AI tools to reject candidates in 2025. That’s a staggeringly high number, but for folks who work in hiring or are currently job hunting it’s not a surprising one. The article offers a further breakdown of how employers plan to use–or are already using–AI in their hiring process.

Large language models (LLMs) are very powerful tools that can help us with a wide range of tasks. These models are usually built with safety features meant to stop them from generating harmful, inappropriate, or otherwise restricted content. However, over time, researchers and enthusiasts have discovered ways to bypass these safeguards—a process known as jailbreaking. In this series of articles, we’re going to show you how to jailbreak one of the most popular open-source models out there: DeepSeek R1. In this opening article, we'll start with prompt jailbreaking. But don’t worry—we’re not just jumping straight into prompt examples. First, we’ll explain what jailbreaking really is, why people do it, and some of the tricky parts you should know about. Sound good? Let’s dive in! DISCLAIMER. This article is for learning and research only. The methods shared here should be used responsibly to test AI, improve security, or understand how these systems work. Please don't use them for anything harmful or unethical.

If you’re into AI agent development, you’ve probably started hearing more and more about a new emerging protocol – Model Context Protocol ( MCP ). In essence, this protocol simplifies how AI agents connect to the data and tools they need. By standardizing these connections, MCP reduces the extra work developers usually have to deal with. Essentially, it replaces the need to directly manage multiple APIs in your AI agent with one unified protocol. And lets you to add/remove any external tools for your agent with incredible ease. Making it more convenient to build complex and flexible AI systems. In this article, we’ll walk you through everything you need to know about MCP—from its core components and main concepts to practical implementations. We will focus specifically on building an MCP server, as it is likely the most useful and frequently used part of the MCP architecture that you will want to implement. So, let’s go! The Model Context Protocol, or MCP, is a simple standard, designed and open sourced by Anthropic to help AI tools talk to the systems where data lives. Think of it like a USB-C port, but for AI applications. Just as a USB-C port lets you connect different devices with one common plug, MCP lets AI models easily connect to various data sources and tools without needing custom code for every connection.

As AI continues to evolve, we’re constantly finding new ways how to improve and to use it. Today, AI has gone much further being just a chat tool. And one of these significant evolutionary steps is the creation and adoption of AI agents. With agents, you can deploy AI solutions that autonomously perform real-world tasks, for example: managing customer support, processing large amounts of information in real-time, and much more! Basically, any task that benefits from working with real-time data and reasoning capabilities. This series of articles will help you not only to grasp the fundamentals of AI agents, but also to get a practical experience of building one yourself. Covering crucial theoretical knowledge and concepts, as well as also learning how to properly apply them in the real world.
