Validate Arbitrage Spreads at Runtime

The `analyze_market_opportunity` tool compares domestic and export bids to find the most profitable market. Pydantic AI validates the returned pricing structure immediately to prevent corrupt trade data from entering your database. If the market API returns an unexpected format, the agent fails loudly instead of processing bad math. This keeps your trading pipeline clean and predictable.

Strict Type-Safe Freight Costing

We use `get_transportation_rate` to pull freight costs per kilometer for rail or vessel transport. The framework guarantees that the returned rate is a valid float before your code executes the next step. You do not have to worry about silent type mismatches in your shipping calculations. The MCP configuration through Vinkius handles the connection while the framework enforces the types.

Guaranteed Net Farm-Gate Calculations in Pydantic AI

The `calculate_farm_gate_parity` tool deducts logistics costs and taxes from the final port price. This yields the exact net value of the crop at the farm gate. Since this MCP returns strictly typed models, your agent can write the results to your ERP with zero parsing errors. You get reliable financial metrics for every grain shipment.

Setup guide

Set up Export Parity Calculator 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": {
        "export-parity-calculator-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Export Parity Calculator transactions")
print(result.output)
