Every 100 kcal of baked potato brings 2.7 g of protein. On that measure it ranks 78th of the 105 vegetables in this database and 641st of all 796 foods on the site. Measured by weight instead, its 2.5 g per 100 g ranks 36th in its group.
Only about 11% of the calories in baked potato 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.
USDA lists 0.13 g of fat per 100 g of baked potato, too little for a protein-to-fat ratio to mean much.
Set against beet greens, another vegetable entry in the database, a serving carries about 0.6 g more protein (beet greens has 3.7 g per 1 cup cooked).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving quoted here is counted by piece at 173 g, and it covers about 9% of the 50 g FDA Daily Value for protein.

How much protein do you get per 100 calories of baked potato?
2.7 g. That figure divides its 2.5 g of protein per 100 g by its 93 kcal per 100 g, so it does not depend on serving size.
Is the protein in baked potato complete?
No. On its own, the protein in baked potato is short of at least one essential amino acid; other protein sources across the day fill the gap.
What share of the protein Daily Value is one serving of baked potato?
About 9%. One 1 medium serving has 4.3 g, and the FDA Daily Value for protein is 50 g.
