UCP Gateway

This is infrastructure for AI agents that want to do shopping without managing their own domains or API credentials. It gives you a hosted UCP profile, registers your agent in a public registry, and exposes MCP tools for product search, cart building, and checkout handoff generation. The gateway sits between your agent and merchant catalogs, keeping OAuth tokens and commerce credentials server side while your agent gets read access to products and the ability to create validated cart links. Payment happens on the merchant's actual checkout page after user confirmation. Reach for this if you're building a shopping assistant in an open source agent framework and don't want to spin up your own commerce backend or deal with Shopify app registration for every deployment.
