Forge reads OPC UA from 23 OEM families and emits the same canonical JSON for every one of them. No per-vendor parser, no per-vendor schema.
One MCP endpoint serves every protocol adapter — there is no per-protocol URL to configure.
Each links to its own mapping reference with vendor-specific tag shapes.
Sampled from the live corpus — one example per vendor, so you can see the same canonical field arriving from different raw tag shapes.
