Addressfinder for AI agents

Addressfinder verifies and autocompletes addresses, emails and phone numbers for Australia, New Zealand and beyond. Developers use it to keep checkout and signup forms accurate. 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 Addressfinder connects.

Users add their Addressfinder 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 Addressfinder 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

Addressfinder and Arc0, answered.

Q01

Can I use Addressfinder with Claude, ChatGPT or Cursor?

Yes. Connect Addressfinder 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 Addressfinder actions you allow.

Q02

How do users connect Addressfinder?

Users add their Addressfinder 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 Addressfinder actions can my agent take?

17 in total: 0 read, 17 write and 0 destructive, such as “get NZ POI Metadata”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Addressfinder?

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

Q05

Can my own backend call Addressfinder too?

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