Fullenrich for AI agents

FullEnrich aggregates data from over 15 vendors to find verified emails and phone numbers for B2B sales leads, used by sales development teams building prospect lists. 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 Fullenrich connects.

Users add their Fullenrich 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 Fullenrich 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

Fullenrich and Arc0, answered.

Q01

Can I use Fullenrich with Claude, ChatGPT or Cursor?

Yes. Connect Fullenrich 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 Fullenrich actions you allow.

Q02

How do users connect Fullenrich?

Users add their Fullenrich 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 Fullenrich actions can my agent take?

9 in total: 6 read, 3 write and 0 destructive, such as “create Contact Data List”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Fullenrich?

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

Q05

Can my own backend call Fullenrich too?

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