Implementation Reference

• server.js:1980-1988 (handler)

  The handler function that executes the "list-endpoints" tool logic by running the kubectl command to list endpoints in the specified or default namespace.

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

• server.js:901-913 (schema)

  The input schema definition for the "list-endpoints" tool, defining an optional namespace parameter.

    name: "list-endpoints",
    description: "List Kubernetes endpoints in a namespace",
    inputSchema: {
      type: "object",
      properties: {
        namespace: { 
          type: "string",
          description: "The namespace to list endpoints from (optional, defaults to current context namespace)"
        }
      }
    }
  },

• server.js:1392-1394 (registration)

  The request handler for listing tools, which includes the "list-endpoints" tool in the returned tools array.

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