Kubernetes MCP Server

Instructions

Implementation Reference

• server.js:1441-1447 (handler)

  The execution handler for the 'list-nodes' tool. It runs the kubectl command 'kubectl get nodes -o wide' and returns the stdout output as text content.

  case "list-nodes": {
    const cmd = `kubectl get nodes -o wide`;
    const { stdout } = await execAsync(cmd);
    return {
      content: [{ type: "text", text: stdout || "No nodes found" }]
    };
  }

• server.js:69-74 (schema)

  The tool schema definition for 'list-nodes', including name, description, and input schema (no required parameters). This is part of the tools list returned by the ListToolsRequestHandler.

  name: "list-nodes",
  description: "List all Kubernetes nodes",
  inputSchema: {
    type: "object",
    properties: {}
  }

• server.js:1392-1394 (registration)

  The ListToolsRequestHandler that registers all tools, including 'list-nodes', by returning the complete tools array.

  server.setRequestHandler(ListToolsRequestSchema, async () => {
    return { tools };
  });
