Validate recipe volume scales at runtime

Your agent calls `convert_volume` to handle the math when scaling recipes, and Pydantic AI guarantees the output matches your exact schema. When scaling recipes, a single bad float can break your database. If the tool returns an unexpected format, your system raises a loud validation error immediately. This prevents silent failures and keeps your application from saving corrupted culinary data.

Type-safe mass estimation for baking apps

By invoking `estimate_mass`, your agent gets the calculated weight of an ingredient volume, wrapped in a strict Pydantic model. Baking is chemistry, and wrong weights ruin results. You define the exact types your application expects, like float grams or integer ounces. The framework ensures the tool output conforms to those types, giving you complete confidence in the numbers.

Verify kitchen units with this MCP Server

Your agent queries `get_unit_details` to get the official abbreviation, regional origin, and scaling factor for any cooking unit. Avoid messy user inputs by looking up unit metadata. By passing this MCP metadata through your custom schemas before it ever reaches your business logic, you catch weird inputs early. This makes your recipe parsing pipeline incredibly stable.

Setup guide

Set up Culinary Unit Converter 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": {
        "culinary-unit-converter-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Culinary Unit Converter transactions")
print(result.output)
