 | `--sse-port`            | Starts the MCP server in Server-Sent Event (SSE) mode and listens on the specified port.                                                                                                                                                                                                      |
 | `--log-level`           | Sets the logging level (values [from 0-9](https://github.com/kubernetes/community/blob/master/contributors/devel/sig-instrumentation/logging.md)). Similar to [kubectl logging levels](https://kubernetes.io/docs/reference/kubectl/quick-reference/#kubectl-output-verbosity-and-debugging). |
 | `--kubeconfig`          | Path to the Kubernetes configuration file. If not provided, it will try to resolve the configuration (in-cluster, default location, etc.).                                                                                                                                                    |

 | `--read-only`           | If set, the MCP server will run in read-only mode, meaning it will not allow any write operations (create, update, delete) on the Kubernetes cluster. This is useful for debugging or inspecting the cluster without making changes.                                                          |
 | `--disable-destructive` | If set, the MCP server will disable all destructive operations (delete, update, etc.) on the Kubernetes cluster. This is useful for debugging or inspecting the cluster without accidentally making changes. This option has no effect when `--read-only` is used.                            |
