Implementation Reference

• src/tools/getMessageQuota.ts:14-29 (handler)

  The register method defines and registers the "get_message_quota" tool with the MCP server, including its handler logic that calls the MessagingApiClient to fetch quota and consumption data.

  register(server: McpServer) {
    server.tool(
      "get_message_quota",
      "Get the message quota and consumption of the LINE Official Account. This shows the monthly message limit and current usage.",
      {},
      async () => {
        const messageQuotaResponse = await this.client.getMessageQuota();
        const messageQuotaConsumptionResponse =
          await this.client.getMessageQuotaConsumption();
        const response = {
          limited: messageQuotaResponse.value,
          totalUsage: messageQuotaConsumptionResponse.totalUsage,
        };
        return createSuccessResponse(response);
      },
    );
