Type-safe product catalog updates

Perform reliable updates to your catalog using `sf_update_product` while relying on Pydantic models to validate every field change. If the API returns unexpected data, the agent stops immediately to prevent data corruption. This strict validation ensures that your product descriptions and active statuses remain consistent. You define your schemas once, and the agent enforces them for every tool execution.

Validate order line items with Pydantic AI

Fetch order details using `sf_order_items` and have the response automatically cast into your defined Python models. This confirms that every quantity and unit price matches your expected types before processing. If the data doesn't align with your model, the agent throws a validation error. This prevents silent failures when dealing with complex order structures.

Query price books with strict schemas

List your price books with `sf_list_pricebooks` and verify the IsStandard flag against your type-safe models. You can confidently pull entries using `sf_pricebook_entries` knowing the output is parsed correctly. This approach eliminates the risk of hallucinated fields or missing values in your pricing data. Your code remains clean and predictable even when handling diverse pricing tiers.

Setup guide

Set up Salesforce Commerce Cloud 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": {
        "salesforce-commerce-cloud-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Salesforce Commerce Cloud transactions")
print(result.output)

Common questions about Salesforce Commerce Cloud MCP in Pydantic AI

It provides runtime validation that prevents corrupted data from entering your system. Every response from the MCP Server is checked against your models, ensuring that your agent acts only on verified data.

Yes, the toolset is designed to map the MCP Server's JSON responses directly to your Pydantic models. This makes working with products and orders type-safe and efficient.

The agent will raise a validation error immediately. This stops the execution flow, protecting your catalog from invalid updates or misinterpreted order details.

Absolutely. You can connect using the standard HTTP or SSE transport options. Just point your MCPToolset to the server URL, and your agent will discover all tools.

Security is maintained through strict token-based authentication and a zero-trust sandbox. The server only processes the specific price book entries you query, with no persistent storage of your proprietary pricing data.
