Type-safe Printify orders with Pydantic AI

Stop guessing the API response structure. Every call to `create_order` is validated against your Pydantic models at runtime to ensure data integrity. If the server returns garbage, your agent stops immediately. This prevents bad data from ever reaching your fulfillment workflow.

Strict product validation in Pydantic AI

Your agent maintains a clean catalog using `update_product` and `list_products`. The framework enforces that all product fields match your expected schema before the agent takes action. You catch schema mismatches before they cause runtime exceptions. It keeps your product data consistent across your entire shop.

Verified shipping data for Pydantic AI

Calculate costs with confidence. The agent uses `calculate_shipping_cost` and validates the returned currency and rate values against your local requirements. You avoid silent failures during checkout. If the cost data is malformed, the agent flags the issue before you process the order.

Setup guide

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

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

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

Common questions about Printify MCP in Pydantic AI

Yes. The framework validates every tool response against your defined Pydantic models. If the Printify API returns an unexpected field, the agent raises a validation error.

You can define a Pydantic model for your products and use the `create_product` tool. The agent ensures the inputs are correct before sending the request to the shop.

Your token is managed by Vinkius and injected into the connection. Your agent never sees the raw credential, keeping your Printify access protected.

Yes. You can configure the MCPToolset to use either SSE or HTTP transports depending on your specific infrastructure needs.

Because it's type-safe, an API error that changes the response format triggers a validation failure. This is much safer than letting the agent guess what went wrong.
