In Captain America 2, Agent Sitwell specifically namedrops Dr Stephen Strange.
One could argue that he is not actually a psychic, per se - but that he has psychic abilities via his control of the mystic forces.
Marvel's own page lists his powers:
Doctor Strange is one of the most powerful sorcerers in existence. Like most sorcerers, he draws his power from three primary sources: the invocation of powerful mystic entities or objects, the manipulation of the universe's ambient magical energy, and his own psychic resources. Strange's magical repertoire includes energy projection and manipulation, matter transformation, animation of inanimate objects, teleportation, illusion-casting, mesmerism, thought projection, astral projection, dimensional travel, time travel and mental possession, to name a few. The full range of his abilities is unknown. Doctor Strange's powers are sometimes less effective against strictly science-based opponents, although he can overcome this limitation with effort.
ComicVine has a great writeup about him and explains further:
Dr. Strange uses mystical energy invoked upon by spells/incantations or by the power of divine beings to manipulate forces of the universe including projection of mystic energy as bolts, slashes, binds, shields, or a scattered array of energy appearing like electricity, manipulating matter and various energies (physical or spiritual) even transmutation of matter, controlling the elements, opening or sealing mystical portals to other realms, teleportation or dimensional travel, reality warping and control over dimension, seeing through or casting illusions, invisibility and intangibility through astral projection, vast mental powers such as telepathy and telekinesis, communication with the dead and spiritual entities, seeing the future or past, manipulating dreams, removing spirits or placing them back into bodies, summoning supernatural beings, or using the powers of supernatural items.
The last highlighted portion fits quite well with the typical definition of a "clairvoyant", particularly with the powers that The Clarivoyant reportedly had.
