Mocean for AI agents

Mocean provides SMS, voice, and WhatsApp messaging APIs for verification codes and customer engagement inside applications that need reliable delivery. 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 Mocean connects.

Users add their Mocean 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 Mocean 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

Mocean and Arc0, answered.

Q01

Can I use Mocean with Claude, ChatGPT or Cursor?

Yes. Connect Mocean 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 Mocean actions you allow.

Q02

How do users connect Mocean?

Users add their Mocean 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 Mocean actions can my agent take?

6 in total: 1 read, 5 write and 0 destructive, such as “voice Dial V2”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Mocean?

Yes. Allow read actions and deny writes in the Mocean policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call Mocean too?

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