I need to typeset a matrix with square brackets as delimiters for math.se (I believe they use MathJaX). How would I do that?

Use {[} as the argument for left delimiter, and similar for the right.
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix}
\begin{document}
\begin{tikzpicture}
\matrix [matrix of math nodes,left delimiter={[},right delimiter={]}]
{
a_8 & a_1 & a_6 \\
a_3 & a_5 & a_7 \\
a_4 & a_9 & a_2 \\
};
\end{tikzpicture}
\end{document}
The matrix was copied directly from the pgf manual (section 38.3 Delimiters), only the delimiters changed. The reason you have to put the braces there is, I suspect, that the delimiter specification is placed within a set of brackets, and you therefore have to separate the delimiter brackets from the brackets for the matrix options.
Can't say about MathJax, but the gauss package does this.
\documentclass{article}
\usepackage{gauss}
\begin{document}
\[
\begin{gmatrix}[p]
1 & 2 & 3 \\
4 & 5 & 6 \\
7 & 8 & 9
\rowops
\swap{0}{1}
\mult{0}{\cdot 7}
\add[5]{1}{2}
\end{gmatrix}
\]
\end{document}
