  We employ the minimal geometric deformation approach to gravitational
decoupling (MGD-decoupling) in order to generate an exact anisotropic and
non-uniform version of the ultracompact Schwarzschild star, or 'gravastar',
proposed by Mazur and Mottola. This new system represents an ultracompact
configuration of radius $R_{S}=2\cal{M}$ whose interior metric can be matched
smoothly to a conformally deformed Schwarzschild exterior. Remarkably, the
model satisfies some of the basic requirements to describe a stable stellar
model, such as a positive density everywhere and decreasing monotonously from
the centre, as well as a non-uniform and monotonic pressure.
