Design

Read-only — only get, describe, logs, and top style operations. No create, update, or delete. If a mutating operation is needed, the server prints the equivalent kubectl command for you to run manually. Safe to use while on-call at night: Claude can never accidentally mutate your cluster, even under prompt fatigue.

Secret-safe — secret values are masked before being sent to the model, so your secrets cannot leak due to misconfiguration or prompt injection.

Token-efficient — responses include only relevant fields (name, status, restarts, etc.) rather than raw Kubernetes API objects, keeping context usage low.

Cluster-aware — every response includes the active context and cluster name, so Claude always knows which cluster it is talking to.

Context-pinned — the server locks to the active kubeconfig context at startup. Switching contexts in another terminal has no effect on the running server.

No extra infra — runs as a local binary or Docker container, connects to whatever kubeconfig context is active at startup.
