Seven.io for AI agents

Seven.io provides APIs for sending SMS and voice messages, managing contacts, and tracking delivery and spend. Businesses use it to reach customers directly on their phones. 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 Seven.io connects.

Users add their Seven.io 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 Seven.io 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

Seven.io and Arc0, answered.

Q01

Can I use Seven.io with Claude, ChatGPT or Cursor?

Yes. Connect Seven.io 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 Seven.io actions you allow.

Q02

How do users connect Seven.io?

Users add their Seven.io 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 Seven.io actions can my agent take?

11 in total: 6 read, 4 write and 1 destructive, such as “create Contact”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Seven.io?

Yes. Actions like “delete Contact” 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 Seven.io too?

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