The MS2PIP Server is a tool to accurately predict peptide fragment ion intensities for mass spectrometry-based proteomics data. It employs the XGBoost machine learning algorithm and is accessible through a RESTful API.

The MS²PIP Server enables any interested researcher to make use of MS²PIP, regardless of their computational experience. It is the only peak intensity prediction server that can predict peak intensities for multiple fragmentation methods, instruments and labelling techniques. The MS2PIP Server has been used as the benchmark for comparison of other recently published tools for the prediction of MS² peak intensities.

The MS2PIP Server is developed at Ghent University and published in Bioinformatics (original server) and Nucleic Acids Research (update 2015 – update 2019).
