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.
What agents do in Bolna.
List an account's voice agents
Read-only list of the voice AI agents and knowledge bases already configured on the account.
Place an outbound call
Trigger an outbound phone call from a named agent after the user approves the call list.
Require approval before deleting an agent
Flag deleting an agent or knowledge base as destructive since it removes a configured voice flow.
35 Bolna actions, graded by risk.
Every Bolna action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

Bolna in three steps.
- 01Your users connect BolnaThey add their Bolna api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, writes like “create Bolna Voice AI Agent (v2)” can wait for the user, and “delete agent by id” can be denied outright.
- 03Any agent can actYour agent calls Bolna through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('bolna', { read: 'allow', write: 'ask', // create_agent destructive: 'deny', // delete_agent_by_id }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
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 →
- AUTH
- API key
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials
- AUDIT LOG
- Every call, on every plan
Use Bolna from any agent.
Bolna and Arc0, answered.
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.
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.
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.
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.
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.
Plug Bolna into your agent.
Your users connect Bolna once, under your brand. Your agent gets 35 actions behind your policies, with every call on the record.
