How to Use the Cronofy MCP in OpenAI Agents SDK

Q: What's the setup process?

It's quick. pip install openai-agents, then point the MCPServerStreamableHttp client at your Vinkius endpoint URL. The agent discovers all the Cronofy tools on its own.

Build production scheduling agents with Cronofy and the OpenAI Agents SDK. Manage events across calendars with built-in guardrails.

Manage Calendar Events Safely

Use `create_event` to book meetings and `delete_event` to cancel them across Google, iCloud, and Exchange. Your OpenAI agent gets direct access to calendar operations without needing separate API keys for each service. Because the OpenAI Agents SDK has built-in guardrails, you can set rules on what events an agent can create or delete. This prevents buggy code from wiping a user's calendar. It's scheduling that's ready for production.

Find Openings for Your OpenAI Agent

The `get_free_busy` tool checks availability for a group of people, while `query_availability` finds open slots based on specific rules. Your agent can use this to find the next open 30-minute slot for a team meeting, no problem. You can hand off this task to a specialized 'scheduler' agent in your system. The OpenAI SDK lets agents collaborate, so a general-purpose agent can pass the scheduling job to one that only has access to Cronofy tools.

Read Unified Calendars in Your MCP Server

The `read_events` tool pulls a unified feed of all events from a user's connected Google, iCloud, and Exchange accounts. Your agent gets a single, clean list to work with instead of three messy ones. All actions get traced in your OpenAI dashboard. When your agent uses `read_events` or `list_calendars`, you see the exact call and response, which makes debugging a thousand times easier. This MCP server simplifies the whole process.

Setup guide

Set up Cronofy 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 Cronofy tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Cronofy MCP in OpenAI Agents SDK

You connect the Cronofy MCP Server to your agent. The agent automatically discovers tools like `create_event` and `query_availability` to manage schedules across Google, iCloud, and Exchange calendars from your Python code.

Yes. The OpenAI Agents SDK is built with guardrails. You can define policies that restrict your agent, for example, only allowing it to `read_events` but not `delete_event`.

Absolutely. The SDK's built-in tracing, agent handoffs, and safety features are designed for deployed applications. This isn't just for prototypes; it's for building real products that manage user calendars.

It's quick. `pip install openai-agents`, then point the `MCPServerStreamableHttp` client at your Vinkius endpoint URL. The agent discovers all the Cronofy tools on its own.

The server only touches calendar data: event details, participant lists, and availability slots. Vinkius isolates each request in a sandbox, and your auth token secures the connection, so your agent's access to calendar information is tightly controlled.
