Dimensionality reduction and feature selection lead to loss of information which may be useful for classification.

The short answer is that there is not a method in scikit-learn to obtain MLP feature importance - you're coming up against the classic problem of interpreting how model weights contribute towards classification decisions. However, there are a couple of great python libraries out there that aim to address this problem - LIME, ELI5 and Yellowbrick:.
