The trio that demolished LOSC Lille last weekend in Kylian Mbappe, Neymar Junior and Lionel Messi led the line once again as the champions looked to continue their flying start to the season.
Although unlike last Sunday, PSG trailed on 20 minutes after Kevin Volland beat Presnel Kimpembe to a through ball from Aleksandr Golovin and dispatched beyond Gialuigi Donnarumma.
The goal-scorer's evening was cut short five minutes later due to a suspected knock he picked up and was rightfully sacrificed for Maghnes Akliouche.
PSG's first meaningful chance happened before the half-hour mark where Neymar had a clever shot blocked before Mbappe disappointingly nodded the follow-up effort over.
Philippe Clement's side threatened a second in the final minutes of the half when Caio Henrique's promising free-kick flew over the wall and forced a scrambling save from Donnarumma.
The Parisans pushed forward towards halftime and were denied by the woodwork from a smart attempt by Messi which dropped back into play and found Mbappe, who went wide.
Monaco nearly increased their tally just after the break from a poor decision by Donnarumma, but Wissam Ben Yedder curled the inviting chance wide.
Goalkeeper Alexander Nubel kept the host at bay minutes later when he pulled off a point-blank save to parry Neymar's rasping attempt.
PSG showed courage in the last 20 minutes and were given a penalty from a foul on Neymar, which the review team approved and the self-same Neymar picked himself up and converted to level matters.
With time running out, the Parisans looked for a late winner and brought on Pablo Sarabia for Messi as well as Nordi Mukiele for Marquinhos.
There were no late drama that followed though, as the two outfits shared the spoils with PSG's perfect start ended.
