DEFINITION
MCP server — A service exposing a system's data (catalog, stock) and actions (quote, order) via the Model Context Protocol, so that any compatible agent can connect to it.
In practice
Technically a thin layer over the merchant's existing APIs, described in a format all compatible models understand. It is the most natural entry point for B2B agentic commerce, where per-account authentication — hence negotiated pricing — is central.
