An open protocol that standardizes how AI applications connect to external data sources, tools, and services.
Friendly Description: MCP, or Model Context Protocol, is a shared language that lets AI tools plug into the apps and data they need. It's like the USB port of the AI world: instead of every AI tool needing a custom adapter for every service, MCP gives them all a common way to connect. That makes it much easier for AI to safely use your calendar, files, or favorite apps.
Example: An AI assistant that supports MCP can connect to your project tracker, your email, and your document library all through the same standard interface. Developers don't have to invent a new connection method for each tool, which means more useful integrations show up faster.
