MCP (Model Context Protocol)
What is MCP (Model Context Protocol)?
MCP is an open standard that lets AI models connect to external tools, data and systems in a uniform way, like a USB port for AI.
A model only becomes useful once it can reach your systems: your CRM, your calendar, your documents, your database. In the past every connection was bespoke. MCP standardizes that: it is an agreement on how an AI model and an external system talk to each other, so you connect tools once and any model can use them.
The comparison with a USB port is useful. Before USB, every device had its own plug, after it everything fit the same port. MCP aims to be that for the connection between AI and the outside world, which makes integrations faster, reusable and less fragile.
For you as a business owner, MCP is not something you need to know yourself, but it is a reason why AI integrations in 2026 are faster and cheaper to build than a year ago. It makes an AIOS layer over your systems more realistic.
