  The handler function that executes the node uncordon operation by patching the Kubernetes node object.

  export async function uncordonNode(args: Record<string, unknown>): Promise<string> {
    const api = getCoreV1Api();
    const name = args.name as string;
    if (!name) throw new Error("Node name is required");
  
    await api.patchNode(
      name,
      { spec: { unschedulable: false } },
      undefined,
      undefined,
      undefined,
      undefined,
      undefined,
      { headers: { "Content-Type": "application/strategic-merge-patch+json" } }
    );
  
    return `Node '${name}' uncordoned — scheduling is re-enabled.`;
  }

• src/tools/kubernetes/index.ts:176-186 (registration)

  The MCP tool registration for 'k8s_uncordon_node', defining its schema and description.

  {
    name: "k8s_uncordon_node",
    description: "Mark a node as schedulable (uncordon) — re-enables pod scheduling",
    inputSchema: {
      type: "object" as const,
      properties: {
        name: { type: "string", description: "Node name" },
      },
