Validated date math in Pydantic AI

With `add_business_days`, you get reliable date offsets that skip holidays. Because the response is validated against Pydantic models, you know exactly what you are getting. Your Pydantic AI agent will fail loudly if the input format deviates from expectations. This prevents silent data corruption in your scheduling logic.

Strict timezone conversion for Pydantic AI

The `convert_timezone` tool provides the exact datetime output you expect. It works perfectly with Pydantic's type checking to ensure your data structures remain intact. Don't risk manual math errors in your Pydantic AI agent workflow. Use this tool to force the model to stick to real-world calendar rules.

Robust scheduling for type-safe agents

This MCP server provides the deterministic output that Pydantic AI requires for high-integrity systems. It removes the ambiguity of model-based date generation. Your Pydantic AI agent benefits from clear tool definitions and runtime validation. It ensures every date operation is verified before the agent proceeds.

Setup guide

Set up Business Timezone & Holiday Scheduler 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": {

Common questions about Business Timezone & Holiday Scheduler MCP in Pydantic AI

You define an MCPToolset and pass it to your agent. It integrates natively with your existing type-safe pipeline.

Yes, it enforces your Pydantic models on every response. Any mismatch causes an immediate validation error.
