Model Context Protocol (MCP)
The Model Context Protocol (MCP) is an open standard for connecting AI models and agents to external tools, data, and systems in real time.
In commerce, MCP is a transport layer that agents use to read live product data and act on merchant systems. The Universal Commerce Protocol supports MCP as one of its integration options, alongside REST APIs and agent-to-agent communication.
MCP is the connective tissue between an AI agent and the systems it operates. For a brand, supporting MCP means an agent can pull current pricing, inventory, and availability directly — rather than relying on a stale crawl or a static feed.
