Notes

Free and open source; you need access to a cluster. The setup guide first creates a ServiceAccount, a kubeconfig for it (mcp-viewer.kubeconfig) and ~/.config/kubernetes-mcp-server.toml with read_only = true. Runtime flags such as --read-only are no longer accepted. With read_only off, tools can delete pods and change resources. Helm tools are an optional toolset, off by default. Needs Node.js for npx, or use the native binary. Codex setup is not documented.
