MLE is usually considered frequentist. See for example the table in https://en.wikipedia.org/wiki/Frequentist_inference https://en.wikipedia.org/wiki/Frequentist_inference Bayesian inference uses the likelihood function but I wouldn't say that this fact alone makes MLE "close to Bayesian". MLE neither considers a (prior) probability distribution nor produces a (posterior) probability distribution for the parameter of interest.
