Quiltt for AI agents

Quiltt provides financial data aggregation for managing connected accounts, transactions, and statements. Fintech product teams use it to build features on top of users' linked bank data. 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 Quiltt connects.

Users add their Quiltt 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 Quiltt 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

Quiltt and Arc0, answered.

Q01

Can I use Quiltt with Claude, ChatGPT or Cursor?

Yes. Connect Quiltt 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 Quiltt actions you allow.

Q02

How do users connect Quiltt?

Users add their Quiltt 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 Quiltt actions can my agent take?

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

Q04

Can I stop my agent from deleting things in Quiltt?

Yes. Actions like “delete Webhook Subscription” 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 Quiltt too?

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