How to Use the Magento (Adobe Commerce) MCP in Pydantic AI

Q: Does Pydantic AI support Magento (Adobe Commerce) category trees?

Yes. Your agent can call mg.listcategories. The MCP server manages egress limits so the massive tree structure will not crash your local validation models.

Q: Can Pydantic AI search for specific Magento (Adobe Commerce) products?

It handles this perfectly. The agent uses mg.searchproducts with pagination. Pydantic AI validates each page of results against your defined schemas before the LLM processes them.

Bring strict type safety to your Magento store. Pydantic AI validates every product, order, and customer payload at runtime.

Perplexity

Validate orders with Pydantic AI

E-commerce APIs return messy JSON, but calling `mg.search_orders` through this framework catches schema changes immediately. The agent pulls recent transactions and checks them against your models. Pydantic AI throws a loud validation error instead of silently corrupting your database if a field is missing. You can safely parse financial records with `mg.list_invoices` knowing the data structure is guaranteed.

Strict checks for stock levels

You cannot afford hallucinations when dealing with inventory, which is why `mg.get_stock` pulls exact numbers directly. The agent also uses `mg.get_product` to fetch the URL-encoded SKU details. Because you define the expected response models, the AI client forces the LLM to respect the actual data. If the model tries to invent a stock count, Pydantic AI blocks it.

Query profiles with an MCP Server

Your agent runs `mg.search_customers` to find the exact account details needed to resolve tickets. It then hits `mg.get_customer` to pull the specific profile using the internal string ID. It can also check the current environment via `mg.get_store_config`. Every single one of these ten tools is exposed through the unified toolset, running over a secure connection.

Setup guide

Set up Magento (Adobe Commerce) 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": {
        "magento-adobe-commerce-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Magento (Adobe Commerce) transactions")
print(result.output)
