Type-safe inventory updates with Pydantic AI

Never worry about an agent corrupting your stock counts. By using Pydantic AI with this MCP Server, tools like `update_inventory` and `list_inventory` are strictly validated against Python type hints before hitting your wholesale catalog. If your LLM tries to pass a string instead of an integer for a stock count, Pydantic AI catches it immediately. The system fails loudly before any invalid data can mess up your warehouse records.

Validate wholesale order schemas at runtime

Wholesale orders have complex nested structures. This integration ensures that when your agent calls `get_order` or `list_orders`, the returned JSON matches your expected Pydantic models exactly. We eliminate silent failures where an LLM hallucinates a missing shipping address or customer ID. Your code gets clean, structured Python objects that you can safely pass to your invoicing systems.

Strict catalog search validation

Keep your product queries predictable. When your agent runs `search_catalog` or `list_products`, Pydantic AI guarantees that the product IDs, categories, and pricing fields conform to your exact data models. This MCP Server provides direct access to your catalog data. You can build customer-facing wholesale bots with confidence because your validation layer will flag API schema updates instantly rather than letting the agent hallucinate a response.

Setup guide

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

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

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

Common questions about Fieldfolio MCP in Pydantic AI

Install `pydantic-ai-slim[mcp]`, then initialize `MCPToolset` with your Vinkius HTTP URL. Pass this toolset into the `toolsets` argument of your Pydantic AI `Agent` constructor to start using the catalog tools.

Pydantic AI will raise a validation error at runtime. This prevents your agent from processing corrupted order data from `get_order` or writing bad values using `update_inventory`.

Yes. The `MCPToolset` supports both SSE and Streamable HTTP transports, allowing your agent to communicate securely with the Fieldfolio tools hosted on Vinkius.

Absolutely. Your agent can call `get_customer` and `list_customers`, with Pydantic AI automatically parsing the retail buyer details into typed Python models for safe manipulation.

Your customer data and wholesale details are protected by Vinkius's zero-trust architecture. Pydantic AI pulls `get_customer` records directly through an ephemeral V8 sandbox, meaning sensitive buyer profiles are never cached or exposed to external servers.
