Abstract The article explores the first exact solution in a four-dimensional EGB-gravity with an anisotropic matter source. The solution has been found by two assumptions, a metric potential and the MIT-bag equation of state. Further, the solution has been tested with several physical constraints. Finally, using the boundary condition we have also estimated the range of bag constant $$\mathcal {B}$$ B by varying the mass of the structure and the Gauss-Bonnet coupling constant $$\alpha $$ α . This allows us to check the physical viability of the solution by comparing it with the existing accepted range of bag constant $$\mathcal {B}$$ B .
