How to generate the exact output polygon using MinimumBoundingGeometry_management tool using arcpy

[SriHarsha]

I have a point feature class with more than 10 million records, when I give the input to MinimumBoundingGeometry_management  geoprocessing tool using CONVEX_HULL geometry type using arcpy module in arcgis ,i am getting the minimum bounding box polygon as the output.But I want the output polygon vertices to exactly align the input features(points).Can anyone help me in this regard ??

You want a 'Concave Hull' not a 'Convex Hull'

You might want to try rfairhur24‌ 's....  Concave Hull Estimator ..... implementation of Bruce Harold's original.

I don't know if he still maintains it though
