Saperly for AI agents

Saperly provides phone numbers, voice calling, and SMS with built-in compliance, acting as telephony infrastructure that AI agents can use to place and manage calls. 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 Saperly connects.

Users add their Saperly 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 Saperly 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

Saperly and Arc0, answered.

Q01

Can I use Saperly with Claude, ChatGPT or Cursor?

Yes. Connect Saperly 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 Saperly actions you allow.

Q02

How do users connect Saperly?

Users add their Saperly 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 Saperly actions can my agent take?

30 in total: 14 read, 14 write and 2 destructive, such as “create Connection”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Saperly?

Yes. Actions like “delete Connection” 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 Saperly too?

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