Fish Audio for AI agents

Fish Audio provides speech synthesis, voice cloning, and conversational voice agents through an API for developers building voice features into apps and products. 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 Fish Audio connects.

Users add their Fish Audio 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 Fish Audio 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

Fish Audio and Arc0, answered.

Q01

Can I use Fish Audio with Claude, ChatGPT or Cursor?

Yes. Connect Fish Audio 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 Fish Audio actions you allow.

Q02

How do users connect Fish Audio?

Users add their Fish Audio 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 Fish Audio actions can my agent take?

10 in total: 6 read, 3 write and 1 destructive, such as “create Agent”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Fish Audio?

Yes. Actions like “delete Agent” 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 Fish Audio too?

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