Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Eventzilla account to Claude via Composio Connect, enabling it to list all upcoming events for this month, show me attendees for your latest event, find all events in the 'Conference' category, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Eventzilla account

Back in Claude, ask it to connect to Eventzilla or give it any Eventzilla-related task.

For example, ask Claude to:

  • "List all upcoming events for this month"
  • "Show me attendees for your latest event"
  • "Find all events in the 'Conference' category"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Eventzilla account is ready to use.

What is the Eventzilla Claude Connector, and what's possible with it?

The Eventzilla MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Eventzilla account. It provides structured and secure access to your event management data, so your agent can perform actions like listing events, retrieving attendee details, exploring event categories, and managing user information on your behalf.

  • Comprehensive event listing and filtering: Ask your agent to fetch all your events or filter them by category, date, or status to get a quick overview of what's coming up or what has happened.
  • Easy attendee and user management: Have your agent list all users associated with your account, making it simple to review or export attendee and staff details.
  • Detailed user profile retrieval: Direct your agent to pull up full profiles for any user, helping you get the context you need without manual searching.
  • Quick access to event categories: Let your agent fetch all available event categories, so you can easily organize, sort, or plan new events based on your needs.

Troubleshooting

1. Why does Claude not use the Composio connector for Eventzilla?

The connector can show as connected, but Claude must use it in each Eventzilla conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Eventzilla again.

2. Why does Claude show an MCP server error before Eventzilla connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Eventzilla.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Eventzilla.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Eventzilla authorization link not work?

The Composio connector is one server. Your Eventzilla account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Eventzilla connection.
  • Composio creates a fresh Eventzilla authorization link.
  • Open that link in your browser and finish the Eventzilla sign-in.

4. Why do Eventzilla actions fail after they worked before?

The Eventzilla connection can expire or lose permission.

  • Ask Claude to inspect the Eventzilla connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Eventzilla account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Eventzilla.
  • If the action still fails with a permission error, check that the connected account has that permission in Eventzilla itself.

5. How do I switch to a different Eventzilla account?

Claude can manage the Eventzilla connection for you.

  • Ask Claude to disconnect or delete the current Eventzilla account.
  • Ask Claude to connect Eventzilla again.
  • Open the new Composio authorization link for Eventzilla.
  • Sign in with the other Eventzilla account in the browser.
  • After the account connects, ask Claude to retry the Eventzilla task.

6. Why is my Eventzilla connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Eventzilla connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Eventzilla tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Eventzilla.

FAQ

Frequently asked questions

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

Yes, you can. Claude Cowork 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 Eventzilla tools.

Yes, absolutely. You can configure which Eventzilla 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 Eventzilla data and credentials are handled as safely as possible.
