Type-Safe Area Program Calculator

Pass a list of room types to `calculate_programmatic_needs` and receive the total programmatic area for the building. Pydantic AI validates the output against your defined models at runtime. If the MCP returns a string instead of a float, the framework fails loudly. You connect by passing your Vinkius HTTP URL to MCPToolset. This unified approach replaces deprecated methods and ensures your agent gets exact schemas. Vinkius reduces token consumption by up to 60 percent during schema negotiation.

Base Area Retrieval

Your agent executes `get_base_area_by_function` to fetch the minimum usable area for any environment type. The data arrives with Ed25519 signatures and a SHA-256 hash chain. You know exactly which values the tool produced. Vinkius AI Analytics tracks these fetch operations. You see exactly what data flows into your Pydantic models. The zero-trust proxy ensures your API keys remain secure in transit and never sit on a disk.

Structural Overhead Math

Agents call `adjust_area_for_structure` to calculate the true gross footprint needed for columns and shear walls. Pydantic AI guarantees the agent passes the correct structural complexity parameters to the tool. You maintain total control over execution costs. The financial circuit breaker monitors spending and stops the agent before it exceeds your budget. Human-in-the-loop approval is required to resume operations.

Setup guide

Set up Area Program 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": {
        "area-program-calculator-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Area Program Calculator transactions")
print(result.output)

Common questions about Area Program Calculator MCP in Pydantic AI

Install pydantic-ai-slim[mcp]. Create an MCPToolset with your Vinkius endpoint. Add the toolset to your Agent instance to begin processing space calculations.

Yes. The framework checks every response against your Pydantic models. Incorrect data types trigger immediate validation errors instead of silent failures.

Yes. The framework is completely model-agnostic. You connect the MCP to local instances or hosted providers without changing your toolset configuration.

A built-in financial circuit breaker tracks token usage across all tool calls. It halts execution if the agent exceeds your set budget.

This MCP processes room dimensions, structural modifiers, and environment classifications. Vinkius runs the calculation inside a sterile V8 isolate. All architectural variables are purged from memory immediately after execution.
