<Callout title="In short">

<Steps>
  <Step>
    ### Before you create a shipment [#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*.
  </Step>

  <Step>
    ### Restock day [#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](/docs/data).
  </Step>

  <Step>
    ### Stranded and aging audit [#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 [#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-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.

<ToolCall tool="fbaInventory_getInventorySummaries" args="{ details: true, seller_skus: [&#x22;SKU-A&#x22;, &#x22;SKU-B&#x22;] }" />
