The present study investigates the heat and mass transfer of MHD viscoelastic (Walters’ B’ model) nanofluid flow over a stretching sheet embedded in a saturated porous medium subject to thermal slip and temperature jump. A simulation model is established through the analysis on relevant constraints such as stretching of bounding surface keeping the origin fixed and thermal slip and temperature jump on the boundary. The numerical solutions are obtained by Runge-Kutta fourth order method with shooting technique. The affects of important thermo-physical parameters on the velocity, temperature, concentration and surface criteria are displayed and analyzed through graphs and tables. As a result of the analysis, the following observations are made. Elasticity of the base fluid in the presence of nanoparticle acts adversely to the growth of velocity as well as thermal boundary layers. Brownian diffusion, thermophoresis and heat source enhance the fluid temperature resulting the cooling of the stretching surface. Further, positive values of heat and mass fluxes for different values of elastic, magnetic and permeability parameters indicate that heat and mass transfer occur from the stretching surface to the fluid. These recommendations are useful to limit the parameters to design viable heat exchangers
