If you’ve been following the rapid evolution of AI tools in 2025 and 2026, you’ve probably heard the term MCP more and more often. But what exactly is the Model Context Protocol, and why is it becoming such a big deal for developers and content teams?
In short: MCP is the emerging universal standard that lets AI agents securely and intelligently connect to external tools, data sources, and applications.
Think of it as “USB-C for AI.”
