Perplexity

Type-Safe Catalog Queries via Pydantic AI

Stop worrying about your model hallucinating inventory numbers. Your Pydantic AI agent uses this MCP Server to run `list_products` and validates the schema before your code ever executes. When calling `get_product_details`, the framework forces the output to match your strict Python models. If BigCommerce returns an unexpected field format, the system catches it immediately.

Strict Order Processing Validation

Processing sales data requires absolute accuracy. The agent calls `list_orders` to fetch recent transactions, parsing every price and status field through runtime checks. Running `get_order_details` ensures that shipping addresses and tax values are perfectly typed. Pydantic AI fails loudly if any crucial field is missing, protecting your downstream accounting databases.

Secure Store Configuration Checks

Keep your multi-tenant architectures aligned. Your agent calls `get_store_info` to grab store configuration details and matches them against your target environment. Using `list_catalog_categories` allows the agent to build structured navigation maps. This ensures your front-end rendering engine never receives malformed category trees.

Setup guide

Set up BigCommerce 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": {
        "bigcommerce-alternative-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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