Wise for AI agents
Wise moves money internationally with transparent exchange rates, used by businesses and individuals sending and holding funds across currencies. 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.
What agents do in Wise.
Get a quote for a transfer
Check the exchange rate and fees for a currency transfer before sending it.
List account balances
Pull balances across held currencies as a read-only check before any transfer.
Confirm before creating a transfer
Get approval before creating a transfer, since it moves money once executed.
9 Wise actions, graded by risk.
Every Wise action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

- 02You set the rulesReads run, and writes like “create Quote” can wait for the user to approve.
- 03Any agent can actYour agent calls Wise through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.

How Wise connects.
Users add their Wise 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 Wise connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →
- AUTH
- API key
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials
- AUDIT LOG
- Every call, on every plan
Use Wise from any agent.

Wise and Arc0, answered.
Can I use Wise with Claude, ChatGPT or Cursor?
Yes. Connect Wise 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 Wise actions you allow.
How do users connect Wise?
Users add their Wise 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.
Which Wise actions can my agent take?
9 in total: 8 read, 1 write and 0 destructive, such as “create Quote”. Your policies decide which of them each agent may call.
Can I make my agent read-only in Wise?
Yes. Allow read actions and deny writes in the Wise policy. Your agent can still look things up, and any write it attempts is blocked and logged.
Can my own backend call Wise too?
Yes. The same Wise connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Wise into your agent.
Your users connect Wise once, under your brand. Your agent gets 9 actions behind your policies, with every call on the record.
