Check FBA stock & restock
Check Amazon's live stock before you act, and run restock, aging and stranded-inventory analysis over your synced inventory reports.
In short
Spot-check live, analyse synced. A live call gives Amazon's numbers right now for a few SKUs; the synced inventory reports answer whole-catalog questions — restock, aging, stranded stock — instantly.
In your daily workflow
Before you create a shipment
fbaInventory_getInventorySummaries returns Amazon's live numbers for the SKUs you are about to send: fulfillable, inbound, reserved and unsellable. Use it when the decision depends on right now.
Restock day
"Which SKUs run out within 3 weeks?" is an analysis over your synced FBA reports — inventory ledger, restock recommendations, aging — through query_report_data. It covers every SKU at once and joins with your sales velocity. See the synced tables.
Stranded and aging audit
The synced stranded-inventory and aging tables show cash quietly stuck in fulfillment centers. Ask for them once a month.
Try asking
"Check live FBA stock for SKU-A and SKU-B in myStore-US."
"Which of my SKUs will run out of FBA stock within 21 days at current sales velocity?"
The spot check, both ways
The same tool and the same arguments — through your AI client, or from your own code.
MCP — you ask: "How many units of SKU-A are fulfillable and inbound right now?" Your agent calls fbaInventory_getInventorySummaries for that SKU and reads the counts back to you.

FAQ
Live or synced — which should I use?
Live is per SKU and counts against Amazon's rate limits; synced covers the whole catalog and answers at once. Spot-check live, analyse synced.
