Rabbi Yaakov Ariel, the Chief Rabbi of Ramat Gan, has denounced the practice of going to Kabbalist rabbis (Mekubalim) for a special blessing in times of trouble. Instead, Jews should [directly] pray to G-d for assistance, he said.
Rabbi Ariel gave his opinion in response to a question on the Yeshiva web site. A reader asked, “We are married for seven years without children. We went to a certain rabbi to get a blessing for a child.
“Before we went in to the rabbi, we had to sign a form obligating us to pay a certain amount if we get pregnant, and another sum if there is a birth. And to invite the rabbi to be the sandak ["godfather"] at the brit milah [circumcision].
“The rabbi saw us for five minutes and said, ‘Bracha v’hatzlacha’ [‘Blessings and success’]. My husband and I got a very bad feeling from it. What does the rabbi [Rabbi Ariel] think of this?”
Rabbi Ariel answered that experts in halakha (Jewish law) oppose the practice of going to rabbis or “kabbalists” for a blessing. “There are some hidden spiritual giants who, through their righteousness, can give blessing,” he said. “But there are few of them, and their identities are not known.”
He urged those in need of blessing to pray to G-d directly, “without an agent.” Those seeking aid can visit the Kotel (Western Wall) or the Tomb of the Patriarchs in Hevron, he added. Rabbi Ariel told the questioner that the commitment she and her husband were required to give may not be valid.

From 1 Samuel 1
5 But to Hannah he gave a double portion, because he loved Hannah, even though Adonai had kept her from having children.
10 In deep depression she prayed to Adonai and cried.
11 Then she took a vow; she said, “Adonai-Tzva’ot, if you will notice how humiliated your servant is, if you will remember me and not forget your servant but will give your servant a male child, then I will give him to Adonai for as long as he lives; and no razor will ever come on his head.”
12 She prayed for a long time before Adonai (the Lord).
17 Then ‘Eli replied, “Go in peace. May the God of Isra’el grant what you have asked of him.”
From the Brit Chadasha, 1 Timothy 2:5
"For God is one;[echad] and there is but one Mediator [agent] between God and humanity, Yeshua the Messiah (who became a man/human)".
John 14
13 In fact, whatever you ask [pray, daven, to G_d) for in my name, I will do; so that the Father (Hashem) may be glorified in the Son (Yeshua).
14 If you ask me for something in my name, I will do it.
