Model Context Protocol, often abbreviated to MCP, is an open‑source standard that lets AI tools, such as Copilot, securely connect to business systems like Dataverse in a consistent way. In Power Apps and model‑driven apps, MCP allows AI features to read and update data, understand tables, and carry out actions using approved permissions—without needing custom integrations for each AI tool. In simple terms, it’s the plumbing that lets AI work safely with your app data rather than guessing or working in isolation.
