Automate holiday lookups for your OpenAI agents

Your agent fetches precise holiday schedules using `list_holidays` without leaving your Python environment. It handles the request lifecycle while you focus on agent logic. This MCP Server provides the data structures your agents need to plan around public closures. You get clean, ready-to-use responses directly from the API.

Validate regional data with OpenAI Agents SDK

Use `list_holidays_by_location` to feed state-specific data into your agent's decision loop. It populates your context window with accurate regional constraints. Your production code treats these results as reliable triggers for task scheduling. You avoid manual data entry by automating the entire lookup process.

Check integration health for OpenAI Agents SDK

Run `get_account_info` to confirm your connection remains active. It reports the status of your integration so your agent knows when to retry requests. This tool ensures your agent stays informed about its own operational state. You catch connection issues before they impact your production agent workflow.

Setup guide

Set up Calendarific MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Calendarific tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Calendarific tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Calendarific tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Calendarific Agent",
            instructions="You have access to Calendarific tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Calendarific MCP in OpenAI Agents SDK

You instantiate the server via MCPServerStreamableHttp and pass it to your Agent constructor. The agent automatically discovers the tools and handles the holiday data requests.

Yes. Simply trigger the `list_holidays_by_location` tool within your agent's execution flow. It returns state-level data filtered for your target country.

Absolutely. You can set cacheToolsList to True to minimize latency during repeated holiday lookups. This keeps your agent responsive while interacting with the API.

The server exposes tools directly to the agent's internal registry. Your code interprets the tool response as native Python objects, keeping your logic type-safe.

Vinkius handles your connection through a secure, ephemeral tunnel. We only process the specific holiday queries you send, keeping your account metadata isolated from other users.
