## Introduction

This guide walks you through connecting Evenium to Mastra AI using the Composio tool router. By the end, you'll have a working Evenium agent that can list all upcoming events for this month, find contacts for our annual conference, show all past events i organized through natural language commands.
This guide will help you understand how to give your Mastra AI agent real control over a Evenium account through Composio's Evenium MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## TL;DR

Here's what you'll learn:
- Set up your environment so Mastra, OpenAI, and Composio work together
- Create a Tool Router session in Composio that exposes Evenium tools
- Connect Mastra's MCP client to the Composio generated MCP URL
- Fetch Evenium tool definitions and attach them as a toolset
- Build a Mastra agent that can reason, call tools, and return structured results
- Run an interactive CLI where you can chat with your Evenium agent

## What is Mastra AI?

Mastra AI is a TypeScript framework for building AI agents with tool support. It provides a clean API for creating agents that can use external services through MCP.
Key features include:
- MCP Client: Built-in support for Model Context Protocol servers
- Toolsets: Organize tools into logical groups
- Step Callbacks: Monitor and debug agent execution
- OpenAI Integration: Works with OpenAI models via @ai-sdk/openai

## 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:
- Node.js 18 or higher
- A Composio account with an active API key
- An OpenAI API key
- Basic familiarity with 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 need credits or a connected billing setup to use the models.
- Store the key somewhere 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.
- This key lets your Mastra agent talk to Composio and reach Evenium through MCP.

### 2. Install dependencies

Install the required packages.
What's happening:
- @composio/core is the Composio SDK for creating MCP sessions
- @mastra/core provides the Agent class
- @mastra/mcp is Mastra's MCP client
- @ai-sdk/openai is the model wrapper for OpenAI
- dotenv loads environment variables from .env
```bash
npm install @composio/core @mastra/core @mastra/mcp @ai-sdk/openai dotenv
```

### 3. Set up environment variables

Create a .env file in your project root.
What's happening:
- COMPOSIO_API_KEY authenticates your requests to Composio
- COMPOSIO_USER_ID tells Composio which user this session belongs to
- OPENAI_API_KEY lets the Mastra agent call OpenAI models
```bash
COMPOSIO_API_KEY=your_composio_api_key_here
COMPOSIO_USER_ID=your_user_id_here
OPENAI_API_KEY=your_openai_api_key_here
```

### 4. Import libraries and validate environment

What's happening:
- dotenv/config auto loads your .env so process.env.* is available
- openai gives you a Mastra compatible model wrapper
- Agent is the Mastra agent that will call tools and produce answers
- MCPClient connects Mastra to your Composio MCP server
- Composio is used to create a Tool Router session
```typescript
import "dotenv/config";
import { openai } from "@ai-sdk/openai";
import { Agent } from "@mastra/core/agent";
import { MCPClient } from "@mastra/mcp";
import { Composio } from "@composio/core";
import * as readline from "readline";

import type { AiMessageType } from "@mastra/core/agent";

const openaiAPIKey = process.env.OPENAI_API_KEY;
const composioAPIKey = process.env.COMPOSIO_API_KEY;
const composioUserID = process.env.COMPOSIO_USER_ID;

if (!openaiAPIKey) throw new Error("OPENAI_API_KEY is not set");
if (!composioAPIKey) throw new Error("COMPOSIO_API_KEY is not set");
if (!composioUserID) throw new Error("COMPOSIO_USER_ID is not set");

const composio = new Composio({
  apiKey: composioAPIKey as string,
});
```

### 5. Create a Tool Router session for Evenium

What's happening:
- create spins up a short-lived MCP HTTP endpoint for this user
- The toolkits array contains "evenium" for Evenium access
- session.mcp.url is the MCP URL that Mastra's MCPClient will connect to
```typescript
async function main() {
  const session = await composio.create(
    composioUserID as string,
    {
      toolkits: ["evenium"],
    },
  );

  const composioMCPUrl = session.mcp.url;
  console.log("Evenium MCP URL:", composioMCPUrl);
```

### 6. Configure Mastra MCP client and fetch tools

What's happening:
- MCPClient takes an id for this client and a list of MCP servers
- The headers property includes the x-api-key for authentication
- getTools fetches the tool definitions exposed by the Evenium toolkit
```typescript
const mcpClient = new MCPClient({
    id: composioUserID as string,
    servers: {
      nasdaq: {
        url: new URL(composioMCPUrl),
        requestInit: {
          headers: session.mcp.headers,
        },
      },
    },
    timeout: 30_000,
  });

console.log("Fetching MCP tools from Composio...");
const composioTools = await mcpClient.getTools();
console.log("Number of tools:", Object.keys(composioTools).length);
```

### 7. Create the Mastra agent

What's happening:
- Agent is the core Mastra agent
- name is just an identifier for logging and debugging
- instructions guide the agent to use tools instead of only answering in natural language
- model uses openai("gpt-5") to configure the underlying LLM
```typescript
const agent = new Agent({
    name: "evenium-mastra-agent",
    instructions: "You are an AI agent with Evenium tools via Composio.",
    model: "openai/gpt-5",
  });
```

### 8. Set up interactive chat interface

What's happening:
- messages keeps the full conversation history in Mastra's expected format
- agent.generate runs the agent with conversation history and Evenium toolsets
- maxSteps limits how many tool calls the agent can take in a single run
- onStepFinish is a hook that prints intermediate steps for debugging
```typescript
let messages: AiMessageType[] = [];

console.log("Chat started! Type 'exit' or 'quit' to end.\n");

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
  prompt: "> ",
});

rl.prompt();

rl.on("line", async (userInput: string) => {
  const trimmedInput = userInput.trim();

  if (["exit", "quit", "bye"].includes(trimmedInput.toLowerCase())) {
    console.log("\nGoodbye!");
    rl.close();
    process.exit(0);
  }

  if (!trimmedInput) {
    rl.prompt();
    return;
  }

  messages.push({
    id: crypto.randomUUID(),
    role: "user",
    content: trimmedInput,
  });

  console.log("\nAgent is thinking...\n");

  try {
    const response = await agent.generate(messages, {
      toolsets: {
        evenium: composioTools,
      },
      maxSteps: 8,
    });

    const { text } = response;

    if (text && text.trim().length > 0) {
      console.log(`Agent: ${text}\n`);
        messages.push({
          id: crypto.randomUUID(),
          role: "assistant",
          content: text,
        });
      }
    } catch (error) {
      console.error("\nError:", error);
    }

    rl.prompt();
  });

  rl.on("close", async () => {
    console.log("\nSession ended.");
    await mcpClient.disconnect();
    process.exit(0);
  });
}

main().catch((err) => {
  console.error("Fatal error:", err);
  process.exit(1);
});
```

      return;
    }

    messages.push({ id: crypto.randomUUID(), role: "user", content: trimmed });

    const { text } = await agent.generate(messages, {
      toolsets: { evenium: composioTools },
      maxSteps: 8,
    });

    if (text) {
      console.log(`Agent: ${text}\n`);
      messages.push({ id: crypto.randomUUID(), role: "assistant", content: text });
    }

    rl.prompt();
  });

  rl.on("close", async () => {
    await mcpClient.disconnect();
    process.exit(0);
  });
}

main();
```

## Conclusion

You've built a Mastra AI agent that can interact with Evenium through Composio's Tool Router.
You can extend this further by:
- Adding other toolkits like Gmail, Slack, or GitHub
- Building a web-based chat interface around this agent
- Using multiple MCP endpoints to enable cross-app workflows

## 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 Mastra AI?

Yes, you can. Mastra AI 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.
