## Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Evenium MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.

## TL;DR

### Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Large tool responses: Handle them to minimise context rot.
- Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.

## Connect Evenium to Codex

### How to install Evenium MCP in Codex
### Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.

```bash
codex mcp add composio --url https://connect.composio.dev/mcp
```

## 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_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. |

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

The Evenium MCP server provides comprehensive access to Evenium operations through Composio. Once connected, you can perform all major Evenium actions directly from Codex using natural language commands.

## Complete Code

None listed.

## Conclusion

### Conclusion
You've successfully integrated Evenium with Codex using Composio's MCP server. Now you can interact with Evenium directly from your terminal, VS Code, or the Codex App using natural language commands.
Key benefits of this setup:
- Seamless integration across CLI, VS Code, and standalone app
- Natural language commands for Evenium operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1000+ apps for cross-app workflows
- CodeAct workbench for complex tool chaining
Next steps:
- Try asking Codex to perform various Evenium operations
- Explore cross-app workflows by connecting more toolkits
- Build automation scripts that leverage Codex's AI capabilities

## 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 Codex?

Yes, you can. Codex 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.
