  A uniform hypergraph $H$ is called $k$-Ramsey for a hypergraph $F$, if no
matter how one colors the edges of $H$ with $k$ colors, there is always a
monochromatic copy of $F$. We say that $H$ is minimal $k$-Ramsey for $F$, if
$H$ is $k$-Ramsey for $F$ but every proper subhypergraph of $H$ is not. Burr,
Erd\H{o}s and Lovasz studied various parameters of minimal Ramsey graphs. In
this paper we initiate the study of minimum degrees and codegrees of minimal
Ramsey $3$-uniform hypergraphs. We show that the smallest minimum vertex degree
over all minimal $k$-Ramsey $3$-uniform hypergraphs for $K_t^{(3)}$ is
exponential in some polynomial in $k$ and $t$. We also study the smallest
possible minimum codegrees over minimal $2$-Ramsey $3$-uniform hypergraphs.
