CurrencyScoop for AI agents

CurrencyScoop provides real-time and historical exchange rates for fiat and cryptocurrencies, letting an app convert amounts or chart currency values. 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 CurrencyScoop connects.

Users add their CurrencyScoop 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 CurrencyScoop 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

CurrencyScoop and Arc0, answered.

Q01

Can I use CurrencyScoop with Claude, ChatGPT or Cursor?

Yes. Connect CurrencyScoop 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 CurrencyScoop actions you allow.

Q02

How do users connect CurrencyScoop?

Users add their CurrencyScoop 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 CurrencyScoop actions can my agent take?

5 in total: 5 read, 0 write and 0 destructive. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in CurrencyScoop?

Yes. Allow read actions and deny writes in the CurrencyScoop policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call CurrencyScoop too?

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