We present the MARD-Y3 catalog of between 1086 and 2171 galaxy clusters (52\%and 65\% new) produced using multi-component matched filter (MCMF) followup in5000\,deg$^2$ of DES-Y3 optical data of the $\sim$20000 overlapping 2RXS X-raysources. Optical counterparts are identified as peaks in galaxy richness as afunction of redshift along the line of sight toward each 2RXS source within asearch region informed by an X-ray prior. All peaks are assigned a probability\fcont\ of being a random superposition. The clusters lie at $0.02<z<1.1$ withmore than 100 clusters at $z>0.5$. Residual contamination is 2.6\% and 9.6\%for the cuts adopted here. For each cluster we present the optical center,redshift, rest frame X-ray luminosity, $M_{500}$ mass, coincidence with NWAYinfrared sources and estimators of dynamical state. About 2\% of MARD-Y3clusters have multiple possible counterparts, the photo-z's are high qualitywith $\sigma_{\Delta z/(1+z)}=0.0046$, and $\sim$1\% of clusters exhibitevidence of X-ray luminosity boosting from emission by cluster AGN. Comparisonwith other catalogs (MCXC, RM, SPT-SZ, Planck) is performed to test consistencyof richness, luminosity and mass estimates. We measure the MARD-Y3 X-rayluminosity function and compare it to the expectation from a fiducial cosmologyand externally calibrated luminosity- and richness-mass relations. Agreement isgood, providing evidence that MARD-Y3 has low contamination and can beunderstood as a simple two step selection-- X-ray and then optical-- of anunderlying cluster population described by the halo mass function.
