Implementation Reference

• src/tools/list-logstores.ts:14-28 (handler)

  The handler function that executes the logic for listing logstores by calling the SLS client.

  export async function handleListLogStores(input: ListLogStoresInput): Promise<string> {
    const logstores = await listLogStores(input.project, input.region);
  
    if (logstores.length === 0) {
      return `No logstores found in project: ${input.project}`;
    }
  
    const lines = logstores.map((l) => `- **${l.logstoreName}**`);
  
    return [
      `Found **${logstores.length}** logstores in project **${input.project}**:\n`,
      lines.join('\n'),
      '\nUse `query_logs` to query log data from a logstore.',
    ].join('\n');
  }

• src/tools/list-logstores.ts:4-10 (schema)

  Input validation schema for the list_logstores tool using Zod.

  export const listLogStoresSchema = z.object({
    project: z.string().describe('SLS project name'),
    region: z
      .string()
      .optional()
      .describe('Alibaba Cloud region ID where the project resides, e.g. cn-hangzhou, cn-shenzhen. Defaults to SLS_REGION env variable.'),
  });

• src/index.ts:25-30 (registration)

  Registration of the 'list_logstores' tool in the main server configuration.

  {
    name: 'list_logstores',
    description:
      'List all logstores within an SLS project. Use this to discover available logstores before querying logs.',
    inputSchema: zodToJsonSchema(listLogStoresSchema) as Tool['inputSchema'],
  },

• src/index.ts:85-88 (handler)

  Tool call handler in the request dispatching logic.

  case 'list_logstores': {
    const input = listLogStoresSchema.parse(args);
    text = await handleListLogStores(input);
    break;
