Walmart Marketplace MCP. Control your full catalog, inventory, and pricing lifecycle.

This server gives your agent direct control over everything you do selling on Walmart Marketplace. Forget manually clicking through dashboards or messing with spreadsheets. You manage your catalog items, set prices, and adjust physical inventory levels using secure tools that talk straight to the platform’s APIs.

Setting Product Pricing:
When you need to update pricing, you've got a few ways to handle it. For setting a single item's price limit, run wm_set_price—it maps structured retail boundaries directly to an item. If you gotta change prices for hundreds of products at once, use wm_bulk_price_update; this tool lets you upload entire batches of pricing payloads and tracking parameters matrices for mass changes.

You also manage sales structures with promotions using wm_setup_promotions, which executes markdown or clearance rule payloads, letting you control your promotional pricing safely.

Syncing Inventory Levels:
Controlling stock is straightforward. When you need to allocate physical units across multiple fulfillment centers and evaluate unit counts in real time, run wm_update_inventory. This keeps your reported stock levels accurate with what's actually on the shelf.

Managing Your Product Catalog:
This suite lets you control every SKU you list. To start, you can use wm_list_items to extract clean arrays of all active third-party seller catalog items currently published on the marketplace. If you need to know what a specific item is worth—like checking buy-box limits or error codes—you run wm_get_item_status.

Before listing anything, you might need Walmart's category structure; for that, use wm_get_taxonomy to retrieve their dynamic category nodes and map necessary structural trees for correct product placement. If an item is done selling or needs to be taken off the market, run wm_retire_item; this unpublishes a specific SKU array and immediately masks it from public view.

Putting It All Together:
Your agent handles the whole seller lifecycle. You can get a complete picture of your product offerings using wm_list_items, then check its status with wm_get_item_status. Next, you use wm_get_taxonomy to figure out where it belongs in Walmart's structure. After that, you might set the price using wm_set_price or run a mass update with wm_bulk_price_update, and then execute sales rules via wm_setup_promotions.

You keep the stock count right by calling wm_update_inventory. Finally, if everything's good to go, you know it's live. If not, you can take it down fast with wm_retire_item.

This setup gives your agent all the hooks needed for complex operations: You’ll never have to worry about manual entry or juggling multiple dashboards again. It handles every aspect of managing a third-party catalog against the platform's live APIs.
