Turn any OPC UA server into an i3X-compliant REST and MCP Enabled API with OpenAPI docs, JSON, and live SSE streams. No OPC UA expertise required.
README
FastAPI gateway implementing the i3X API over OPC UA — exposes OPC UA address spaces as standardized REST and MCP endpoints with JSON responses, OpenAPI docs, and Server-Sent Event subscriptions. Built for teams that do not have deep OPC UA expertise.
The Industrial Information Interoperability Exchange (i3X™) is an open, common API initiative proposed to address a growing interoperability challenge in modern manufacturing architectures: manufacturing data silo proliferation and API chaos. As manufacturers adopt heterogeneous software stacks from multiple vendors, the industry risks repeating past fragmentation seen with protocols, platforms, and namespaces - this time at the API layer.
