From the developer:
MPCluster -Find clusters in your Microsoft® MapPoint® data points.MPCluster identifies groups or clusters in your MapPoint data. MPCluster can then draw a boundary shape around each cluster and/or mark each cluster's center with a pushpin. MPCluster supports most of MapPoint's different dataset types, but is typically used with pushpin (point) datasets or shaded area datasets.
MPCluster lets you set the maximum number of clusters to find.
