How to Use the Notion Calendar (formerly Cron) MCP in OpenAI Agents SDK

Q: How do I handle timezone differences using Notion Calendar (formerly Cron) with the OpenAI Agents SDK?

The createevent tool accepts standard ISO format strings with offset indicators. Your agent parses user input, normalizes the timezone, and writes the correct block directly to the Notion API.

Q: What happens if an agent tries to double-book a slot?

The agent should run getfreebusy before creating any entry. If an overlap exists, the model catches the conflict in its reasoning loop and selects an alternative slot instead of forcing the event.

Let your OpenAI Agents SDK coordinate meetings and block time directly inside Notion Calendar without manual API integrations.

Perplexity

Check availability with this MCP Server

`get_availability` checks team calendars directly to find open slots before your agent suggests a meeting time. This MCP Server queries the Notion Calendar API in real time, avoiding the lag of cached scheduling tools. Your agent runs this check autonomously inside its execution loop, matching calendar blocks against raw text inputs. It gets back clean JSON arrays representing free windows, letting the model make decisions based on actual open slots.

Draft and update events via active agent loops

`create_event` builds calendar invites on the fly when your agent extracts a meeting request from a chat thread. The tool maps raw strings to ISO timestamps, ensuring timezone shifts do not mess up the invite. If plans change, the agent fires `update_event` to shift the block or swap attendees instantly. You do not have to write manual code, handle double-booking errors, or deal with API boilerplate.

Inspect team calendars to resolve schedule conflicts

`list_calendars` queries the user's active Notion Calendar profiles to map out which schedules require coordination. The agent uses this list to isolate work calendars from personal ones, keeping scheduling logical. Combining this with `list_events` lets your OpenAI Agents SDK scan existing blocks to find soft-commit conflicts. Your agent can then run `update_event` to slide overlapping blocks to tomorrow without human intervention.

Setup guide

Set up Notion Calendar (formerly Cron) 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 Notion Calendar (formerly Cron) tools at runtime.
3

Create your Agent

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

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Notion Calendar (formerly Cron) 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="Notion Calendar (formerly Cron) Agent",
            instructions="You have access to Notion Calendar (formerly Cron) tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Notion Calendar (formerly Cron) MCP in OpenAI Agents SDK

Vinkius handles the OAuth flow for this MCP Server entirely behind the scenes, giving you a single endpoint token. You pass this token to `MCPServerStreamableHttp` inside your Python code, and your OpenAI Agents SDK gets instant access to all calendar tools.

Yes, you can filter the tool list during agent initialization in Python. Simply restrict the tools array to specific functions like `get_availability` if you want to block write access like `delete_event`.

The `create_event` tool accepts standard ISO format strings with offset indicators. Your agent parses user input, normalizes the timezone, and writes the correct block directly to the Notion API.

The agent should run `get_free_busy` before creating any entry. If an overlap exists, the model catches the conflict in its reasoning loop and selects an alternative slot instead of forcing the event.

Your calendar events and scheduling links never sit on our servers. Vinkius runs a zero-trust, ephemeral V8 sandbox that passes payloads directly between your OpenAI agent and the Notion API, discarding memory footprints immediately after execution.
