MCP (Model Context Protocol)
Updated
The Model Context Protocol is an open protocol that lets AI applications connect to external tools and data through one standard interface: a server exposes tools, resources and prompts, and an AI client discovers and calls them.
In practice
An MCP server for IoT connectivity lets an AI agent list SIMs, read usage or order a top-up within the permissions you grant it, instead of a person working in a web console.
