Perplexity

Type-safe order validation

Every call to `create_production_order` is validated against your Pydantic models. If the server returns data that doesn't match your schema, Pydantic AI stops the execution immediately. This prevents silent corruption in your production database. You define the structure, and the agent enforces it, ensuring your orders are always formatted correctly.

Strict inventory tracking

Call `list_inventory_stocks` and let your Pydantic models verify the response. You get immediate feedback if the data is missing fields or contains invalid types. This is essential for keeping your production line stable. You don't have to write manual checks for every field returned by the MCP Server; the framework handles the validation for you.

Reliable manufacturing audits

Get consistent data from `get_production_order_details` to feed your reporting systems. Pydantic AI guarantees that your agent receives exactly what the model expects. Stop worrying about hallucinated fields or incorrect types. The integration ensures that your agent logic remains predictable, even when the underlying data is complex.

Setup guide

Set up Fusion Operations 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": {
        "fusion-operations-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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