wtf is go-mdcb?

Tyk's go-mdcb is a Go programming library that lets you talk to a Tyk MDCB server from your own Go code. MDCB is Tyk's control plane, the central hub that manages multiple API gateway instances spread across different locations. This client gives you a simple, pre-built way to ask that hub what's going on: which gateway nodes are currently connected, whether the system is healthy, and deep performance diagnostics when something feels off. At a practical level, the library wraps a handful of HTTP calls so you don't have to construct them yourself. You can retrieve a list of all connected data plane nodes (the individual gateways actually handling traffic), run a health check to see if the control plane is up and responsive, and pull CPU profiling data through Go's built-in pprof tooling for performance debugging. You import the package into your Go project, optionally point it at a specific server URL, and call the functions it exposes. This would be useful for teams already running Tyk as their API gateway across multiple regions or environments. A platform engineer might use it to build a custom dashboard showing which gateway nodes are online at any given moment. An on-call developer could wire it into alerting logic so that when a data plane drops off, a script automatically fetches the current node list and health status to include in an incident report. The profiling endpoints would appeal to someone investigating why a control plane is running hot or slow under heavy load. One thing worth noting is that the library was auto-generated from an OpenAPI specification rather than hand-written. That's a common and legitimate approach, it means the code stays consistent with the API definition and can be regenerated if the API changes, but it also means the code style leans heavily on generated patterns like pointer-based model structures, which is why the package includes helper functions for working with them. The README doesn't claim the endpoints require authentication, which suggests this is intended for internal use within a trusted network rather than over the public internet.
