CallOnTheGo for AI agents

CallOnTheGo runs voice AI calling campaigns, managing phone numbers, contact lists, and suppression lists so outreach stays compliant while dialing at scale. 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.

CallOnTheGo and Arc0, answered.

Q01

Can I use CallOnTheGo with Claude, ChatGPT or Cursor?

Yes. Connect CallOnTheGo 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 CallOnTheGo actions you allow.

Q02

How do users connect CallOnTheGo?

Users add their CallOnTheGo 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 CallOnTheGo actions can my agent take?

29 in total: 14 read, 12 write and 3 destructive, such as “create Campaign”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in CallOnTheGo?

Yes. Actions like “delete Caller ID” 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 CallOnTheGo too?

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