No, it's not an alcohol.
Alcohols = R-OH
When R= alkyle

MgXOH or (X-Mg-OH) typically refers to a Grignard's Reagent.

It's more correct to represent it as R-Mg-OH. R is so polarised by magnesium that R is effectively an anion. R is an alkyl group.

Grignard reagents are always carbon based.  This would just be a magnesium halide hydroxide salt.

OK. I never encountered such a salt (in textbook and lab) before.
