Implementation Reference

• server.js:1567-1575 (handler)

  The handler function that implements the core logic for the 'describe-configmap' tool by executing the 'kubectl describe configmap' command with the provided configmap name and optional namespace.

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

• server.js:246-262 (schema)

  The input schema definition for the 'describe-configmap' tool, including parameters for configmap name (required) and optional namespace.

    name: "describe-configmap",
    description: "Describe details of a Kubernetes configmap",
    inputSchema: {
      type: "object",
      properties: {
        configmap: { 
          type: "string",
          description: "The name of the configmap to describe"
        },
        namespace: { 
          type: "string",
          description: "The namespace of the configmap (optional, defaults to current context namespace)"
        }
      },
      required: ["configmap"]
    }
  },

• server.js:1392-1394 (registration)
