Developer Resources
Open-source packages for Commerce Gateway, the integration and MCP product. This page covers the OSS distribution from a package/developer perspective; for the product story see Commerce Gateway → Self-hosting.
The underlying technology ships under the @commercegateway/* npm scope, with
the registry protocol published as the unscoped commerce-registry-protocol —
