AltText.ai for AI agents

AltText.ai automatically generates alt text for images to improve accessibility and search visibility. E-commerce teams and publishers use it to describe product photos and blog images at scale. 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 AltText.ai connects.

Users add their AltText.ai 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 AltText.ai 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

AltText.ai and Arc0, answered.

Q01

Can I use AltText.ai with Claude, ChatGPT or Cursor?

Yes. Connect AltText.ai 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 AltText.ai actions you allow.

Q02

How do users connect AltText.ai?

Users add their AltText.ai 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 AltText.ai actions can my agent take?

10 in total: 5 read, 4 write and 1 destructive, such as “create Image”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in AltText.ai?

Yes. Actions like “delete Image by Asset 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 AltText.ai too?

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