Validate customer queries with Pydantic AI

The `search_customers` tool retrieves detailed profiles, lifetime value, and order history with strict type validation. Pydantic AI ensures that every field, from email addresses to club status, matches your schema exactly before your agent sees it. If the Commerce7 API returns unexpected null values, the framework raises a validation error immediately. This prevents your agent from acting on corrupt or incomplete customer data.

Enforce strict schemas on wine order data

The `get_order` tool fetches specific purchase records including itemized lists, shipping addresses, and order totals. Your agent uses this tool to answer post-purchase support questions with absolute precision. By routing these payloads through this MCP Server, the system guarantees that financial figures like tax and shipping are typed as floats, not strings. You avoid calculation errors in your automated billing workflows.

Prevent inventory hallucinations

The `list_inventory` tool returns exact bottle counts across your winery's storage locations. Pydantic AI validates these integers at runtime to ensure your agent never reads a hallucinated stock number. When paired with `get_product`, the agent cross-references active wine details with actual physical stock. You can confidently automate stock alerts knowing the data is validated at the MCP application boundary.

Setup guide

Set up Commerce7 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": {
        "commerce7-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Commerce7 tools.",
)

result = await agent.run("List recent Commerce7 transactions")
print(result.output)
