fix(auth): ensure OIDC auth plugin is included in compiled binary

[ziadmoubayed]

Summary:

This PR fixes startup failures when the server is pointed at clusters that authenticate with OIDC.
We add a single side-effect import:

import _ "k8s.io/client-go/plugin/pkg/client/auth/oidc"

which registers the OIDC plug-in at init() time so that client-go can recognise the auth-provider: oidc stanza found in many kubeconfigs.

Motivation:

Running npx [email protected] against an OIDC-backed cluster produced:

Failed to initialize MCP server: no Auth Provider found for name "oidc"

I am not a go expert. Please let me know if the import should be place somewhere else

Thx! This is awesome (maybe we want to add other plugins too).

To keep things in the same domain package, maybe it's better if we add the plugin import in between these lines:

kubernetes-mcp-server/pkg/kubernetes/kubernetes.go

Lines 14 to 15 in 2bd12f8

	"k8s.io/client-go/kubernetes"
	"k8s.io/client-go/rest"

and remove it from the cmd/root.go

could you please check if this works too?

LGTM, thx!

Thanks for the review. I did a test today. It works now. Facing #83 unfortunately.

Continued the support in #105
