ContactOut for AI agents

ContactOut finds and verifies professional contact details, letting a recruiter or sales team turn a LinkedIn profile into a working email address. 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 ContactOut connects.

Users add their ContactOut 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 ContactOut 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

ContactOut and Arc0, answered.

Q01

Can I use ContactOut with Claude, ChatGPT or Cursor?

Yes. Connect ContactOut 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 ContactOut actions you allow.

Q02

How do users connect ContactOut?

Users add their ContactOut 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 ContactOut actions can my agent take?

25 in total: 15 read, 9 write and 1 destructive, such as “create Bulk Email Verification Job”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in ContactOut?

Yes. Actions like “remove Campaign Recipients” 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 ContactOut too?

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