We place observational constraints on a scalar-tensor gravity theory by comparing the WMAP temperature and polarization angular spectrum with its predictions. We examined the quadratic extension of Brans-Dicke theory and found that, even if the scalar-tensor theory was far from Einstein gravity in early cosmological epochs, CMB can set stringent constraints on the deviations from Einstein gravity.
