Appointo for AI agents

Appointo is an appointment booking app built for Shopify stores, letting merchants add online scheduling for services and products directly on their storefront without custom code. 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.

04 · AUTH AND DATA

How Appointo connects.

Users add their Appointo 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 Appointo connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Appointo and Arc0, answered.

Q01

Can I use Appointo with Claude, ChatGPT or Cursor?

Yes. Connect Appointo 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 Appointo actions you allow.

Q02

How do users connect Appointo?

Users add their Appointo 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.

Q03

Which Appointo actions can my agent take?

11 in total: 5 read, 5 write and 1 destructive, such as “create Booking”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Appointo?

Yes. Actions like “cancel Booking” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Appointo too?

Yes. The same Appointo connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
