Implementation Reference

• server.js:1558-1565 (handler)

  Handler for the 'describe-node' tool. Extracts the 'node' argument, runs 'kubectl describe node <node>', and returns the command output as text content.

  case "describe-node": {
    const { node } = args;
    const cmd = `kubectl describe node ${node}`;
    const { stdout } = await execAsync(cmd);
    return {
      content: [{ type: "text", text: stdout || "No node details found" }]
    };
  }

• server.js:234-243 (schema)

  Input schema for the 'describe-node' tool, defining a required 'node' string parameter.

  inputSchema: {
    type: "object",
    properties: {
      node: { 
        type: "string",
        description: "The name of the node to describe"
      }
    },
    required: ["node"]
  }

• server.js:232-244 (registration)

  Registration of the 'describe-node' tool in the tools array, which is returned by the listTools handler. Includes name, description, and input schema.

    name: "describe-node",
    description: "Describe details of a Kubernetes node",
    inputSchema: {
      type: "object",
      properties: {
        node: { 
          type: "string",
          description: "The name of the node to describe"
        }
      },
      required: ["node"]
    }
  },
