## TL;DR

Here's what you'll learn:
- Get and set up your OpenAI and Composio API keys
- Install the necessary dependencies
- Initialize Composio and create a Tool Router session for Evenium
- Configure an AI agent that can use Evenium as a tool
- Run a live chat session where you can ask the agent to perform Evenium operations

## What is OpenAI Agents SDK?

The OpenAI Agents SDK is a lightweight framework for building AI agents that can use tools and maintain conversation state. It provides a simple interface for creating agents with hosted MCP tool support.
Key features include:
- Hosted MCP Tools: Connect to external services through hosted MCP endpoints
- SQLite Sessions: Persist conversation history across interactions
- Simple API: Clean interface with Agent, Runner, and tool configuration
- Streaming Support: Real-time response streaming for interactive applications

## What is the Evenium MCP server, and what's possible with it?

The Evenium MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Evenium account. It provides structured and secure access to your event management data, so your agent can retrieve event details, pull contacts, and manage user sessions on your behalf.
- Event listing and retrieval: Quickly fetch a comprehensive list of your upcoming or past events, with optional filters for targeted searches.
- Contact management: Effortlessly pull organizer and attendee contact lists to streamline outreach and follow-ups for your events.
- Session management and logout: Direct your agent to explicitly log out and invalidate sessions, ensuring enhanced security after event tasks are completed.
- Automated event insights: Use AI-powered assistants to analyze and summarize event data, helping you stay organized and make informed decisions.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `EVENIUM_CREATE_CONTACT` | Create Contact | Tool to create a new contact in the Evenium address book. Use when you need to add a new contact with basic information (name, email, company) and optional custom fields. |
| `EVENIUM_DELETE_CONTACT` | Delete Contact | Tool to permanently remove a contact from the Evenium address book. Use when you need to delete a contact by their ID. WARNING: This operation is irreversible and deletes all associated guests in cascade. |
| `EVENIUM_GET_CONTACT` | Get Contact | Tool to retrieve a single contact by ID from Evenium. Use when you need to fetch details for a specific contact using either Evenium internal ID or custom external ID. |
| `EVENIUM_GET_CONTACT_BY_CUSTOM_ID` | Get Contact by Custom ID | Tool to retrieve a specific contact from Evenium by their custom ID (external database ID). Use when you need to look up a contact using an identifier from your own CRM or database system. |
| `EVENIUM_GET_CONTACT_EVENTS` | Get Contact Events | Tool to retrieve all events that a contact has been invited to or registered for. Use when you need to see a contact's event history with registration details. |
| `EVENIUM_GET_CONTACT_EVENTS_BY_CUSTOM_ID` | Get Contact Events by Custom ID | Retrieves all events a contact has been invited to using their custom ID. Use this when you need to find all events associated with a specific contact identified by a custom ID from your database. |
| `EVENIUM_GET_CONTACTS` | Get Contacts | Tool to retrieve a list of contacts from Evenium. Use when you need to fetch and optionally filter organizer contacts. |
| `EVENIUM_GET_EVENTS` | Get Events | Retrieves a paginated list of events from Evenium with optional filtering and sorting. Use this to list all events or search for specific events by title, code, or location. Supports pagination via start/limit parameters and sorting via sort/direction parameters. By default, returns active events only; use filter flags to include archived, deleted, or draft events. |
| `EVENIUM_IMPORT_CONTACTS` | Import Contacts | Tool to import multiple contacts at once (batch import). Creates new contacts or updates existing ones based on customId or email matching. Use when you need to bulk create or update contacts in Evenium. |
| `EVENIUM_LOGOUT` | Logout | Tool to log out the current user and invalidate the session token. Use when you need to explicitly end the current session. |
| `EVENIUM_UPDATE_CONTACT` | Update Contact | Tool to update an existing contact in Evenium by contact ID. Use when you need to modify contact details such as email, name, company, or custom fields. |
| `EVENIUM_UPDATE_CONTACT_BY_CUSTOM_ID` | Update Contact by Custom ID | Tool to update a contact in Evenium by custom ID (external ID from your CRM/database). Use when you need to update contact details using your own identifier rather than Evenium's internal ID. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Evenium MCP server is an implementation of the Model Context Protocol that connects your AI agent to Evenium. It provides structured and secure access so your agent can perform Evenium operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before starting, make sure you have:
- Composio API Key and OpenAI API Key
- Primary know-how of OpenAI Agents SDK
- A live Evenium project
- Some knowledge of Python or Typescript

### 1. Getting API Keys for OpenAI and Composio

OpenAI API Key
- Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models, or you can connect to another model provider.
- Keep the API key safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Go to Settings and copy your API key.

### 2. Install dependencies

Install the Composio SDK and the OpenAI Agents SDK.
```python
pip install composio_openai_agents openai-agents python-dotenv
```

```typescript
npm install @composio/openai-agents @openai/agents dotenv
```

### 3. Set up environment variables

Create a .env file and add your OpenAI and Composio API keys.
```bash
OPENAI_API_KEY=sk-...your-api-key
COMPOSIO_API_KEY=your-api-key
USER_ID=composio_user@gmail.com
```

### 4. Import dependencies

What's happening:
- You're importing all necessary libraries.
- The Composio and OpenAIAgentsProvider classes are imported to connect your OpenAI agent to Composio tools like Evenium.
```python
import asyncio
import os
from dotenv import load_dotenv

from composio import Composio
from composio_openai_agents import OpenAIAgentsProvider
from agents import Agent, Runner, HostedMCPTool, SQLiteSession
```

```typescript
import 'dotenv/config';
import { Composio } from '@composio/core';
import { OpenAIAgentsProvider } from '@composio/openai-agents';
import { Agent, hostedMcpTool, run, OpenAIConversationsSession } from '@openai/agents';
import * as readline from 'readline';
```

### 5. Set up the Composio instance

No description provided.
```python
load_dotenv()

api_key = os.getenv("COMPOSIO_API_KEY")
user_id = os.getenv("USER_ID")

if not api_key:
    raise RuntimeError("COMPOSIO_API_KEY is not set. Create a .env file with COMPOSIO_API_KEY=your_key")

# Initialize Composio
composio = Composio(api_key=api_key, provider=OpenAIAgentsProvider())
```

```typescript
dotenv.config();

const composioApiKey = process.env.COMPOSIO_API_KEY;
const userId = process.env.USER_ID;

if (!composioApiKey) {
  throw new Error('COMPOSIO_API_KEY is not set. Create a .env file with COMPOSIO_API_KEY=your_key');
}
if (!userId) {
  throw new Error('USER_ID is not set');
}

// Initialize Composio
const composio = new Composio({
  apiKey: composioApiKey,
  provider: new OpenAIAgentsProvider(),
});
```

### 6. Create a Tool Router session

What is happening:
- You give the Tool Router the user id and the toolkits you want available. Here, it is only evenium.
- The router checks the user's Evenium connection and prepares the MCP endpoint.
- The returned session.mcp.url is the MCP URL that your agent will use to access Evenium.
- This approach keeps things lightweight and lets the agent request Evenium tools only when needed during the conversation.
```python
# Create a Evenium Tool Router session
session = composio.create(
    user_id=user_id,
    toolkits=["evenium"]
)

mcp_url = session.mcp.url
```

```typescript
// Create Tool Router session for Evenium
const session = await composio.create(userId as string, {
  toolkits: ['evenium'],
});
const mcpUrl = session.mcp.url;
```

### 7. Configure the agent

No description provided.
```python
# Configure agent with MCP tool
agent = Agent(
    name="Assistant",
    model="gpt-5",
    instructions=(
        "You are a helpful assistant that can access Evenium. "
        "Help users perform Evenium operations through natural language."
    ),
    tools=[
        HostedMCPTool(
            tool_config={
                "type": "mcp",
                "server_label": "tool_router",
                "server_url": mcp_url,
                "headers": {"x-api-key": api_key},
                "require_approval": "never",
            }
        )
    ],
)
```

```typescript
// Configure agent with MCP tool
const agent = new Agent({
  name: 'Assistant',
  model: 'gpt-5',
  instructions:
    'You are a helpful assistant that can access Evenium. Help users perform Evenium operations through natural language.',
  tools: [
    hostedMcpTool({
      serverLabel: 'tool_router',
      serverUrl: mcpUrl,
      headers: { 'x-api-key': composioApiKey },
      requireApproval: 'never',
    }),
  ],
});
```

### 8. Start chat loop and handle conversation

## Conclusion

This was a starter code for integrating Evenium MCP with OpenAI Agents SDK to build a functional AI agent that can interact with Evenium.
Key features:
- Hosted MCP tool integration through Composio's Tool Router
- SQLite session persistence for conversation history
- Simple async chat loop for interactive testing
You can extend this by adding more toolkits, implementing custom business logic, or building a web interface around the agent.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Evenium MCP?

With a standalone Evenium MCP server, the agents and LLMs can only access a fixed set of Evenium tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Evenium and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with OpenAI Agents SDK?

Yes, you can. OpenAI Agents SDK fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Evenium tools.

### Can I manage the permissions and scopes for Evenium while using Tool Router?

Yes, absolutely. You can configure which Evenium scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Evenium data and credentials are handled as safely as possible.
