We propose a threshold detector for L\'evy distributed fluctuations based ona Josephson junction. The L\'evy noise current added to a linearly ramped biascurrent results in clear changes in the distribution of switching currents outof the zero-voltage state of the junction. We observe that the analysis of thecumulative distribution function of the switching currents supplies informationon both the characteristics shape parameter $\alpha$ of the L\'evy statisticsand the intensity of the fluctuations. Moreover, we discuss a theoretical modelwhich allows to extract characteristic features of the L\'evy fluctuations froma measured distribution of switching currents. In view of this results, thissystem can effectively find an application as a detector for a L\'evy signalembedded in a noisy background.
