Medusa
EcosystemOpen-source headless commerce framework whose modular backend could support a custom UCP integration; no public UCP package has been verified.
Medusa is an official UCP ecosystem participant. Source →
Medusa is an open-source headless commerce platform with modular order, inventory, customer, and pricing services. Its extension model makes it a plausible base for a custom UCP service.
As of July 23, 2026, UCPList could not verify a public medusa-plugin-ucp package on npm. Teams should not assume a drop-in module exists: use Medusa's documented module APIs and the official UCP schemas, samples, and conformance tests to evaluate a custom integration.
Why This Matters for UCP
Medusa provides an extensible commerce backend that teams can evaluate as the foundation for a custom UCP implementation.

Good UCP support. Endpoint is stable and well-documented. The only minor friction was rate limits during initial testing — easy to request an increase.

The UCP capabilities are complete and work as advertised. Our shopping agent handles product discovery and checkout end-to-end through this platform.

Reliable endpoint. We run automated conformance checks weekly and they pass consistently. The identity linking spec is fully implemented.

We plugged this into our agent framework and had live product discovery working within a day. The platform integration is clean.
