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 Sympla account to Claude via Composio Connect, enabling it to show all upcoming published events, list past events sorted by date, find unpublished draft events this month, and more such actions on your behalf without compromising your account security.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 Sympla account

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

For example, ask Claude to:

  • "Show all upcoming published events"
  • "List past events sorted by date"
  • "Find unpublished draft events this month"

It will prompt you to authenticate and authorize access.

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

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

The Sympla MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Sympla account. It provides structured and secure access to your event management data, so your agent can perform actions like listing events, filtering by status, sorting results, and accessing event details on your behalf.

  • Comprehensive event listing: Ask your agent to fetch a complete list of all events you've created, streamlining your event management process.
  • Status-based event filtering: Easily filter your events by published status, so you can quickly find ongoing, upcoming, or draft events.
  • Custom event sorting: Sort your event listings by date, name, or other supported criteria for easier review and management.
  • Access detailed event information: Let your agent retrieve key event details to help with monitoring, reporting, or planning tasks.

Troubleshooting

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

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

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

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

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

  • 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 Sympla.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Sympla authorization link not work?

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

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

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

The Sympla connection can expire or lose permission.

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

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

Claude can manage the Sympla connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Sympla 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 Sympla.

FAQ

Frequently asked questions

With a standalone Sympla MCP server, the agents and LLMs can only access a fixed set of Sympla tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Sympla 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 Sympla tools.

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