Model Context Protocol (MCP) is an open standard developed by Anthropic that allows AI assistants like Claude, ChatGPT, and Gemini to securely connect with external applications and live data sources. Instead of relying on pre-trained knowledge, MCP gives AI tools a structured, permission-controlled channel to query real systems. The Magento 2 AI Agent MCP Integration by MageDelight implements this standard to connect your AI assistant directly to your live store data.
