Bolna for AI agents

Bolna is a voice AI platform that businesses use to build conversational agents, place outbound calls, and manage the knowledge bases those agents draw on. 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 Bolna connects.

Users add their Bolna 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 Bolna 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

Bolna and Arc0, answered.

Q01

Can I use Bolna with Claude, ChatGPT or Cursor?

Yes. Connect Bolna 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 Bolna actions you allow.

Q02

How do users connect Bolna?

Users add their Bolna 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 Bolna actions can my agent take?

35 in total: 17 read, 14 write and 4 destructive, such as “create Bolna Voice AI Agent (v2)”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Bolna?

Yes. Actions like “delete agent by 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 Bolna too?

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