Abstract
We exhibit gluing properties of cluster tilting subcategories in exact -categories within the framework of perverse schobers on surfaces with boundary. These results are based on a study of the restriction functors from global sections of perverse schobers to local sections and their adjoint induction functors. New examples include cluster tilting subcategories in higher rank topological Fukaya categories related to higher Teichm\"uller theory, and cluster tilting subcategories arising from marked surfaces with punctures.
