A typical 1 oz serving of cream cheese contains 1.7 grams of protein (6.15 g per 100 g), which makes it only a minor source of protein. That covers roughly 3% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Only about 7% of the calories in cream cheese come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
Among the 81 dairy foods in the database, cream cheese ranks 76th by protein per serving, and 673rd out of all 796 foods on the site. Set against sweet whey powder, another dairy food entry in the database, a serving carries about 0.7 g more protein (sweet whey powder has 1 g per 1 tbsp).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is measured by weight at 28 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
Cream cheese is mostly fat and water, so it is one of the lowest-protein cheeses.
