FAQ from MCP Server Kubernetes

What are the prerequisites to use MCP Server Kubernetes?

You need kubectl installed and in your PATH, a valid kubeconfig file with configured contexts, and access to a Kubernetes cluster (e.g. minikube, Rancher Desktop, GKE). Helm v3 is optional but required for Helm features.

How do I verify the connection to my cluster?

Run kubectl get pods in a standard terminal to check connectivity. If successful, ask Claude to list pods or create a test deployment.

What is non-destructive mode?

Non-destructive mode restricts the server to read and create/update-only operations, preventing destructive actions. It is enabled via the ALLOW_ONLY_NON_DESTRUCTIVE_TOOLS environment variable (see ADVANCED_README.md).

Does MCP Server Kubernetes support Helm?

Yes, it supports Helm v3 for installing charts with custom values, uninstalling releases, upgrading existing releases, and working with namespaces, version specification, and custom repositories.

What runtime does MCP Server Kubernetes require?

The server is built with Bun and can be run via npx (Node.js) or directly with Node after building. Local development requires Bun installed.
