Feathery for AI agents

Feathery is a form-building platform with advanced logic for data intake workflows, letting teams build and manage custom forms for onboarding, applications, and document signing. 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 Feathery connects.

Users add their Feathery 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 Feathery 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

Feathery and Arc0, answered.

Q01

Can I use Feathery with Claude, ChatGPT or Cursor?

Yes. Connect Feathery 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 Feathery actions you allow.

Q02

How do users connect Feathery?

Users add their Feathery 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 Feathery actions can my agent take?

19 in total: 0 read, 17 write and 2 destructive, such as “list Forms”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Feathery?

Yes. Actions like “delete Form” 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 Feathery too?

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