# Walmart Drop Ship Vendor MCP MCP

> Walmart Drop Ship Vendor MCP gives you full proxy control over 1P supplier logistics. Manage everything from polling active DSV orders to tracking node latency and allocating stock counts across your supply chain locations. It lets you run complex, audited fulfillment operations directly linked to Walmart's internal catalog.

## Description

Managing a drop ship operation requires juggling dozens of moving parts: inventory levels must match outstanding orders; transit times change constantly; every shipment needs an accurate Advanced Shipping Notice (ASN). This MCP gives your agent the specific access needed to handle complex, 1st Party supplier logistics directly through Walmart's internal endpoints. You can poll for open DSV orders, track warehouse node latency, and push precise stock counts across multiple physical locations.

When you combine this with other services—say, running inventory checks here then feeding those results into a messaging MCP to alert the carrier—you build an automation that spans multiple platforms. This is where Vinkius really shines; it lets your agent chain these different tools together so you don't have to manually pass data between systems. Every call runs through their zero-trust proxy, meaning your keys are used only in transit and never stored on disk. The result is a highly secure, auditable process that keeps complex fulfillment moving without human intervention.

## Tools

### dsv_cancel_lines
Cancels DSV lines by parsing unfulfilled constraints for 1P seller structures.

### dsv_check_node_status
Polls and checks the operational status of 1P distribution centers.

### dsv_get_orders
Extracts all actively created Drop Ship Vendor orders in structured logs.

### dsv_get_packing_slips
Retrieves packing documents needed for accurate warehouse tracking constraints.

### dsv_manage_inventory
Adjusts physical 1P logistic stock by pushing precise inventory updates.

### dsv_route_shipments
Verifies local transport carriers and ensures shipments are correctly routed to the right nodes.

### dsv_submit_asn
Executes advanced shipping notices by mapping physical tracking updates for supplier shipments.

### dsv_update_lag_time
Updates fulfillment lag days and tracks the latency of 1P supplier nodes.

## Prompt Examples

**Prompt:** 
```
Check active and unfulfilled DSV sales orders.
```

**Response:** 
```
Query completed. Exported currently unfulfilled packaging arrays efficiently.
```

**Prompt:** 
```
Summarize the current Lag Times for facility ID 'WH-EAST'.
```

**Response:** 
```
Based on your query, the current default Lag Time for physical node 'WH-EAST' is configured to 2 days before mandatory shipment.
```

**Prompt:** 
```
Prepare an Advanced Shipping Notice (ASN) for package PLT-444 containing 5 units of SKU-10.
```

**Response:** 
```
ASN Generated successfully. Package PLT-444 is registered in transit and the DSV dashboard has been updated.
```

## Capabilities

### Get Active Orders
Pull structured logs of all open Drop Ship Vendor orders currently needing attention.

### Check Node Status
Poll the system to verify if specific 1P distribution centers are running efficiently and available for use.

### Adjust Stock Levels
Force updates to physical inventory counts across various warehouse locations.

### Update Transit Time
Execute tracking updates to report current fulfillment lag days and node latency accurately.

### Submit Shipment Notices
Generate Advanced Shipping Notices (ASN) that formally register supplier shipments in the system.

## Use Cases

### The Node is Down
A warehouse manager needs to know if a key distribution center, 'WH-EAST', is operational. The agent runs dsv_check_node_status and confirms the node is active before routing any new shipments.

### Rush Order Fulfillment
A large batch of orders comes in late on a Friday. The agent first uses dsv_get_orders, then runs dsv_manage_inventory to allocate stock, and finally executes dsv_submit_asn for tracking.

### Correcting Shipment Errors
A shipment is flagged incorrectly. Instead of calling support, the agent uses dsv_cancel_lines to void the wrong line item, then uses dsv_route_shipments to confirm the correct path.

### Planning for Delays
The planner runs a sequence: first checking node status (dsv_check_node_status), then calling dsv_update_lag_time to see if current latency will delay the next wave of orders.

## Benefits

- Stop manually tracking delays. Use dsv_update_lag_time to get current fulfillment lag days, knowing exactly when shipments will hit the node.
- Never lose track of stock. The dsv_manage_inventory tool lets you push accurate, real-time stock counts directly into the system.
- Generate paperwork instantly. Pull necessary packing slip directives using dsv_get_packing_slips for immediate warehouse action.
- Keep orders flowing. Running dsv_get_orders pulls all active DSV sales orders in one go, eliminating manual dashboard polling.
- Finalize shipments cleanly. Use dsv_submit_asn to generate the required advanced shipping notices and update tracking status.

## How It Works

The bottom line is you control the full flow: from pulling raw order data to pushing final shipment status updates.

1. First, tell your agent which specific node or order batch you need to focus on.
2. Next, the MCP executes the necessary sequence of calls—maybe checking inventory then updating lag times—to build a complete operational picture.
3. You get back structured data confirming orders were pulled, stock was adjusted, or ASNs were successfully generated.

## Frequently Asked Questions

**Can I use dsv_get_orders with my existing messaging platform?**
Yes, you can chain these tools. Your agent pulls the orders using dsv_get_orders and then sends that structured data directly to your messaging MCP so your team gets instant notifications.

**What happens if I use dsv_cancel_lines incorrectly?**
The tool isolates clean 1P seller structures, meaning it only handles official lines. Always confirm the order status first using dsv_get_orders before attempting a cancellation.

**Does dsv_check_node_status tell me how busy a warehouse is?**
It tells you if the distribution center is running efficiently and available. For capacity, you'd need to cross-reference this with your inventory data using dsv_manage_inventory.

**How do I update shipment status after a sale?**
You run dsv_submit_asn first to formally register the package in transit, and then use dsv_update_lag_time to report the expected new arrival window.

**If I use `dsv_manage_inventory` to update stock, how does it prevent me from over-allocating units?**
The MCP validates all inventory pushes against the live 1P records. It stops you before committing any changes if your requested allocation would result in a negative or impossible count.

**Is submitting an Advanced Shipping Notice (`dsv_submit_asn`) secure, given the sensitive data involved?**
Yes, it is. Your credentials pass through Vinkius's zero-trust proxy and are never stored on disk. This keeps your key material isolated while enabling the transaction.

**Are there rate limits when calling `dsv_get_orders` to pull a large volume of order data?**
Yes, standard API rate limits apply. For high-volume needs, we recommend setting up a dedicated webhook listener rather than making repeated polling calls.

**What is the optimal sequence: Should I run `dsv_route_shipments` before or after updating lag time using `dsv_update_lag_time`?**
You should update the expected delay first. Using `dsv_update_lag_time` establishes the timeline, allowing `dsv_route_shipments` to verify correct node paths based on that new schedule.
