The Short Answer
Only if your layover is long, at least 14 to 16 hours. Agra is roughly 230 km from Delhi airport, about 3.5 to 4 hours each way, and you need time for immigration, the Taj and getting back for check-in. Shorter than that and the sensible plan is a Delhi city tour instead.
Most passport holders also need an Indian visa (an e-visa works) to leave the airport; check yours before you book. Every tour below is a real listing you can message about before you pay: WhatsApp +91 84495 38716 or email, and a person answers.
