Clearout for AI agents

Clearout verifies email addresses and finds contact emails, helping sales and marketing teams keep lists clean and reach the right inbox. 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 Clearout connects.

Users add their Clearout 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 Clearout 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

Clearout and Arc0, answered.

Q01

Can I use Clearout with Claude, ChatGPT or Cursor?

Yes. Connect Clearout 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 Clearout actions you allow.

Q02

How do users connect Clearout?

Users add their Clearout 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 Clearout actions can my agent take?

21 in total: 0 read, 19 write and 2 destructive, such as “find Domain MX Records”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Clearout?

Yes. Actions like “cancel Bulk Email Finder Job” 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 Clearout too?

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