Finmo for AI agents

Finmo handles payment collection, payouts, wallets, and foreign exchange for businesses moving money across borders, used by companies with international customers and suppliers. 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 Finmo connects.

Users add their Finmo 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 Finmo 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

Finmo and Arc0, answered.

Q01

Can I use Finmo with Claude, ChatGPT or Cursor?

Yes. Connect Finmo 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 Finmo actions you allow.

Q02

How do users connect Finmo?

Users add their Finmo 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 Finmo actions can my agent take?

19 in total: 13 read, 5 write and 1 destructive, such as “create Payin”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Finmo?

Yes. Actions like “create Refund” 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 Finmo too?

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