Magic Hour for AI agents

Magic Hour is an AI media creation platform for generating and editing images, videos, and voice through a single API. 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 Magic Hour connects.

Users add their Magic Hour 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 Magic Hour 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

Magic Hour and Arc0, answered.

Q01

Can I use Magic Hour with Claude, ChatGPT or Cursor?

Yes. Connect Magic Hour 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 Magic Hour actions you allow.

Q02

How do users connect Magic Hour?

Users add their Magic Hour 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 Magic Hour actions can my agent take?

38 in total: 6 read, 29 write and 3 destructive, such as “create AI GIF”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Magic Hour?

Yes. Actions like “delete Audio Project” 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 Magic Hour too?

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