Discover how MCP makes Al truly useful — connecting assistants to codebases, databases, workflows, and beyond.
Many developers have heard of MCP (Model Context Protocol), but far fewer understand what it actually does, how to use it safely, and why it has the potential to reshape how we build AI-integrated software. Whether you’re a junior dev starting out, or a senior architect designing large systems, knowing MCP (its design, strengths, limits) is becoming essential.

This article dives deep into what MCP is, its internals, how to use it effectively, real-world examples, potential dangers, and future directions.
