Telnyx for AI agents

Telnyx provides voice, messaging, and networking infrastructure that developers wire into their own products, and here lets an agent look up account and network configuration. 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 Telnyx connects.

Users add their Telnyx 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 Telnyx 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

07 · FAQ

Telnyx and Arc0, answered.

Q01

Can I use Telnyx with Claude, ChatGPT or Cursor?

Yes. Connect Telnyx 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 Telnyx actions you allow.

Q02

How do users connect Telnyx?

Users add their Telnyx 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 Telnyx actions can my agent take?

30 in total: 21 read, 5 write and 4 destructive, such as “create Network”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Telnyx?

Yes. Actions like “delete Network” 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 Telnyx too?

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