Hi Gaurav,
GeoServer can do interpolation on point data sets on the fly, based on the
Barnes Surface algorithm,
there is no official documentation but you can read a bit about it here:
https://boundlessgeo.com/2012/08/surface-interpolation-in-geoserver/
And then there is a process to extract contour lines from raster data:
http://docs.geoserver.org/stable/en/user/styling/sld/extensions/rendering-transform.html#contour-extraction
However, we don't have support for going directly from points to contours,
and chaining the two rendering
transformations above is something that is also not officially supported
(we haven't looked into this use case,
I'm guessing it's not going to work).
The software is open, so maybe you can make changes into it to get chaining
rendering trasformations work
(if you do, please share back with the community your fixes), or you can
have someone do it for you as part
of a commercial contract, see here:

Cheers
Andrea
