Gamma-ray burst (GRBs) are primary targets for all modern IACT telescope. The MAGIC collaboration has identified the detection of GRBs in the VHE regime as one of its multi-year key observational programs (KOP). However, the transient and unpredictable nature of GRBs makes pointing and rapid follow-up observations to observe the prompt emission phase difficult for large ground-based Cherenkov facilities. Thanks to its fast pointing speed and low-energy sensitivity, MAGIC is particularly well suited for GRB studies in the VHE range below ~100 GeV during the prompt-to-early afterglow phase. Since beginning operation in 2005, MAGIC has performed 72 follow-up observations that, to date, have yielded no significant detections. However, in the last two years, the MAGIC system upgrade and an improved GRB observation procedure has made possible follow-up of GRBs within ~100s after the event onset, hence opening a new phase in MAGIC GRB monitoring. In this contribution, I will show the achieved MAGIC performance for prompt observations and transient source detection, and will also report results from some GRB MAGIC observations.
