Perplexity

Handle Complex DSV Order Retrieval

You use `dsv_get_orders` to extract every actively created Drop Ship Vendor order. The tool resolves native structured logs inherently cleanly, giving you reliable data points. Because the response is validated by Pydantic, you never get a hallucinated field or corrupted record—if the API sends bad data, your agent fails loudly.

Verify Shipment Routing Paths

The framework validates inputs for `dsv_route_shipments`. This checks local transport carriers and ensures bounds are correctly targeted. You get accurate node paths every time. This level of type safety means you don't have to manually check if the carrier ID or route format is right before sending.

Check Node Health with Type Safety

Before running anything, you need status. The `dsv_check_node_status` tool polls logical Node arrays to verify 1P distribution center bounds are efficient. Pydantic ensures the output structure matches your expected schema. This validation means your downstream processes won't break just because a field name changed on the server side.

Setup guide

Set up Walmart Drop Ship Vendor MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.

Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "walmart-drop-ship-vendor-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Walmart Drop Ship Vendor tools.",
)

result = await agent.run("List recent Walmart Drop Ship Vendor transactions")
print(result.output)
