Sympla for AI agents
Sympla is an event management platform for in-person and online events, handling ticket sales, registrations, and digital content broadcasting. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

How Sympla connects.
Users add their Sympla api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.
The same Sympla connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

Sympla and Arc0, answered.
Can I use Sympla with Claude, ChatGPT or Cursor?
Yes. Connect Sympla to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Sympla actions you allow.
How do users connect Sympla?
Users add their Sympla api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.
Which Sympla actions can my agent take?
1 in total: 1 read, 0 write and 0 destructive. Your policies decide which of them each agent may call.
Can I make my agent read-only in Sympla?
Yes. Allow read actions and deny writes in the Sympla policy. Your agent can still look things up, and any write it attempts is blocked and logged.
Can my own backend call Sympla too?
Yes. The same Sympla connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Sympla into your agent.
Your users connect Sympla once, under your brand. Your agent gets 1 actions behind your policies, with every call on the record.
