6 Must-Have MCP Servers (and How to Use Them)
The era of AI agents has arrived, and with it, a new standard for how they connect to tools: the Model Context Protocol (MCP). MCP unlocks powerful, flexible workflows by letting agents tap into external tools and systems. But with thousands of MCP servers (including remote ones) now available, it’s easy to ask: Where do… ⌘ Read more

Docker + Unsloth: Build Custom Models, Faster
Building and Running Custom Models Is Still Hard Running AI models locally is still hard. Even as open-source LLMs grow more capable, actually getting them to run on your machine, with the right dependencies, remains slow, fragile, and inconsistent. There’s two sides to this challenge: Model creation and optimization: making fine-tuning and quantization efficient. Model… ⌘ Read more
