Model Context Protocol (MCP)

EcosystemVerified

Anthropic's open protocol for connecting AI models to external data sources and tools, complementary to UCP.

Model Context Protocol (MCP) is an open protocol developed by Anthropic that standardizes how AI models connect to external data sources, tools, and systems. While UCP governs commerce interactions (checkout, catalog, orders), MCP governs how AI models access context from databases, APIs, and applications. The two protocols are complementary: MCP helps AI agents gather context, while UCP enables them to execute commerce transactions.

Why This Matters for UCP

MCP complements UCP by providing AI agents with contextual information (user preferences, product data) that informs their UCP-powered shopping decisions and checkout flows.

Integration Example

// MCP and UCP work together in agentic commerce:
// 1. Agent uses MCP to access user preferences and product context
// 2. Agent uses UCP to discover merchants and complete checkout
// The combination enables context-aware, personalized shopping agents.
