Type-Safe Financials in Pydantic AI

This MCP calculates margins and targets bad inventory. You trigger `calculate_product_margins` to compute the baseline profitability for your provided list of products. Pydantic AI validates every single number that comes back. If the API returns a string instead of a float, the framework fails loudly. You get guaranteed correct data instead of silent corruption in your financial reports.

Flag the Losers Automatically

The numbers don't lie. Use `detect_underperforming_products` to identify products failing to meet industry minimum profitability thresholds. Your agent forces the output into strict data models. You know exactly which SKUs to cut because the framework guarantees the structure of the failure list. No hallucinated product codes.

Model Cost Reductions

You need to know the payoff before squeezing suppliers. The `simulate_cogs_savings_impact` tool forecasts projected gross margin improvements from proposed cost cuts. Connect the MCP through Vinkius and run the simulation. The agent checks the forecasted delta against your target schemas. If the math doesn't align with your strict types, the run terminates before you make a bad decision.

Setup guide

Set up Gross Margin Analyzer 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": {
        "gross-margin-analyzer-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Gross Margin Analyzer transactions")
print(result.output)
