No, EASA provides the AMOC approval only to the applicant (the AMOC approval holder) that has applied for it and, if relevant, to the authority of state of registry (in case of an application coming directly from an operator).
Therefore EASA does not publish AMOCs to its web site, or add the AMOCs to the AD tool - as it does for PADs and ADs.
Where an AMOC to an EASA AD is of generic nature e.g. not limited to a few aircraft, this should lead to a revision of the affected AD. The AD would then be posted to EASA's website and the alternative method of compliance in that way then made public.
