Perplexity

Type-Safe Stock Management

`list_inventory` returns structured stock data that is validated against strict Pydantic models at runtime. If the warehouse API returns an unexpected payload, your application catches the schema mismatch immediately. This strict validation prevents corrupt data from creeping into your database. Your agent works with reliable numbers, eliminating the risk of ghost inventory and overselling.

Guaranteed Order Creation

`create_logistics_order` requires specific parameters like recipient addresses and SKU quantities. The Pydantic AI framework validates these inputs locally before making the network call. By catching malformed address formats or negative stock counts early, you save API credits and reduce transaction failures. You get clean, predictable execution on every order.

Validating Inbound Shipments with this MCP Server

`list_inbounds` tracks freight shipments coming into your distribution centers. The server returns structured shipment statuses that your agent parses into strongly-typed Python objects. If a shipment status changes, `get_inbound` fetches the exact details. The agent then updates your internal ERP without relying on loose, unvalidated JSON dictionaries.

Setup guide

Set up Flexport Logistics 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.
2

Configure the FastMCPToolset
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": {
        "flexport-logistics-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Flexport Logistics transactions")
print(result.output)
