Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Evenium.

This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Evenium account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to Evenium

Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.

Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

Connect Evenium to Atomic Agent

  1. Sign up or sign in to the Composio dashboard. Copy your API key.
  2. In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
  3. Ask Atomic Agent to do something in Evenium. It searches Composio for the right tool.
  4. On first use, open the sign-in link returned in the chat. Connect your Evenium account, then return to Atomic Agent to continue.

Headless setup

Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY

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.

Use Evenium from Atomic Agent

With your account connected, ask Atomic Agent to work with Evenium in natural language. You can connect more apps through the same Composio integration as you need them.

Visit the Atomic Agent website or inspect the Atomic Agent source code.

Troubleshooting

Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See Composio pricing for the current limits that apply to your connection.

FAQ

Frequently asked questions

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.

Yes, you can. Atomic Agent 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.

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.

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.
