Universal Commerce Protocol (UCP)
A commerce protocol for discovery, purchase, and post-purchase flows.
What is Universal Commerce Protocol (UCP)?
Universal Commerce Protocol (UCP) is part of the commerce protocols vocabulary. In practice, it describes a commerce protocol for discovery, purchase, and post-purchase flows. The exact implementation varies by platform, but the useful meaning stays the same: it helps teams name a specific part of how products, content, AI answers, or commerce operations work.
Why it matters
Universal Commerce Protocol (UCP) matters because agentic commerce needs shared rules for discovery, checkout, authorization, and tool access. Protocols reduce one-off integrations between agents and merchants.
