Rupeezy's default brokerage on commodity futures and options is ₹20 per order. The exact rate depends on the plan on your account — see our pricing page for what applies to yours.
Brokerage is only Rupeezy's own fee. A commodity trade also carries statutory charges set by the exchange and the government — CTT, exchange transaction charges, GST, SEBI charges and stamp duty. Those are listed segment by segment in What are MCX transaction and other charges?, and you can see an estimate for any specific order before you place it with View Charges.
