How to Use the Calenso MCP in OpenAI Agents SDK

Q: How do I connect Calenso to the OpenAI Agents SDK?

Install openai-agents via pip and configure the MCP streamable HTTP transport. Initialize MCPServerStreamableHttp with your Vinkius endpoint URL and pass it to the Agent constructor. The SDK automatically discovers all eight booking tools.

Q: What is the best way to speed up tool discovery?

Set cacheToolsList=True in your SDK configuration. This prevents the agent from making extra network requests to fetch the tool definitions on every turn. Your application loads faster as a result.

Run your Calenso booking operations with guardrails using the OpenAI Agents SDK.

Sync Calenso branches and staff to OpenAI Agents

The `list_calenso_branches` tool lets your agent find physical locations before suggesting times to users. This runs before checking who is available to work. Once the client finds the location, it calls `list_calenso_staff` to match customers with the right team member. You don't have to hardcode location IDs or staff schedules in your prompt.

Safe booking creation with this MCP Server

This MCP Server exposes `create_calenso_customer` to register new users before scheduling their slots. Your production pipeline checks customer identity before writing data. The agent validates inputs at runtime, blocking bad phone numbers or emails. Tracing on the OpenAI dashboard shows exactly when the customer profile was written.

Instant appointment management and cancellations

The `cancel_calenso_appointment` tool removes scheduled blocks when a customer requests a change. Your agent handles the cancellation request natively without human intervention. The system pulls current bookings first using `list_calenso_appointments` to verify the ID exists. It prevents accidental deletions by confirming details before execution.

Setup guide

Set up Calenso 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 Calenso tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Calenso MCP in OpenAI Agents SDK

Install `openai-agents` via pip and configure the MCP streamable HTTP transport. Initialize `MCPServerStreamableHttp` with your Vinkius endpoint URL and pass it to the Agent constructor. The SDK automatically discovers all eight booking tools.

You control access by managing the tool list passed to your agent configuration. If you only want to allow booking reads, omit the cancellation tool from the exposed schema. This keeps your production environment safe from unauthorized changes.

You can route booking requests to a specialized scheduling agent while keeping a general agent for customer inquiries. The specialized agent takes over when the user asks to run `list_calenso_services`. It hands control back once the booking is complete.

Set `cacheToolsList=True` in your SDK configuration. This prevents the agent from making extra network requests to fetch the tool definitions on every turn. Your application loads faster as a result.

Your customer names, emails, and appointment details remain secured within the Vinkius sandbox. Every request goes through an ephemeral V8 isolate that destroys its state immediately after the tool run finishes. No customer data is stored on our servers.
