NO, I don't consider MDMA a psychedelic!
MDMA is entactogenic-empathogen in the first place; one of the most emotogenic-stimulants. It has a psychedelic ingredient, but that's not the main one. Psychedelic ingredient is there like a spice in culinary sauce or delicacy.
MDMA's mode of action is principally different than psychedelics. Genuine psychedelics are 5HT2a ligands and have primary effects on that receptor... Psychedelics are those tryptamines, phenethylamines and ergolines which cause their effects via mentioned 5HT2a receptor. And MDMA, although phenethylamine, is not 5HT2a ligand as far as I know. It has some effects on that receptor, but as far as I know those are caused metabolic products of MDMA...
I think that MDMA's effects are very unique* It works differently than stimulants, in general and psychedelics. How produces hormone Oxytocin... and especially the way MDMA pumps serotonin flowing into synapse from inside the cell, contrary to its normal way to flow routes by reversing the action of transporter... and then it works also as reuptake inhibitor of serotonine, dopamine and norepinephrine (like usual stimulants ie. cocaine forexample). So, that should be
truly unique way of action. MDMA may just because of these actions produce oxytocin like it does. MDMA is not like psychedelics, but neither like other stimulants.
Similarly, MDMA still contains or includes a stimulant component, but I don't consider it plain stimulant either. In my experience MDMA is still much more a stimulant than psychedelic; it just produce as much feeling as psychedelics (in other mode of action). But stimulant component is present as main ingredient, And, if you could have asked "do you consider MDMA a stimulant?", I would have had harder time while deciding, I would have said, the most probably, "Yes, but do you mean in the strictest sense like plain stimulant? Then I have to say, NO, I don't consider MDMA a strict stimulant, but an empathogenic or emotogenic stimulant, YES! That empathia and emotional component comes from serotonin, and there is that reuptake inhibition there TOO!
MDMA is less a psychedelic than it is a stimulant. Psychedelic drugs or psychedelics are those which profoundly hit the 5HT2a receptor

. And TRUE psychedelics could have, and in fact they indeed contain, differening amounts of other components in them. Mescaline has, for example, as phenethylamine a stimulating component in it, and I could usually walk a country mile on it (or stay still an hour while watching something), but I still feel clearly that energic charge and mescaline is very different substance than psilocin...
Well, MDMA is serotonergic amphetamine, and has untypically strong emotional kick but in different way than psychedelic and other serotonergic amphetamines which are psychedelics: DOB, DOC or DOI and TMA, TMA2... DOB and siblings (so 5HT2a ligands). MDMA is UNIQUE sort of serotonin pump: "Not only does MDMA inhibit the reuptake of serotonin, but it reverses the action of the transporter so that it begins pumping serotonin into the synapse from inside the cell" (
http://www.ncbi.nlm.nih.gov/pubmed/17209801). Some other substituted amphetamines (not psychedelic ones) could inhibit reuptake of serotonin, but MDMA PUMPS SEROTONIN!
Hopefully that very brief presentation, clearuption cleared the matter a little. I just wanted to explain why I don't think MDMA is psychedelic, although it gives the feeling kick and in some degree, MDMA has also psychedelic component. It still feeels very different, AND acts very differently.
With its own sort of action
MDMA is empathogenic-entactogen or emotogenic-stimulant .
* I remember that A. Shulgin was criticizing the way people used the word "unique" in differentiating or identification purposes, when people spoke about how unique some drug was in effects... because all drugs are unique in their effects according Shulgin. But I think it is appropriate to use unique NOW.... because I do it correctly
