Findymail for AI agents

Findymail is a B2B contact data provider that finds and verifies email addresses and phone numbers for sales outreach, used by SDRs building prospecting 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 Findymail connects.

Users add their Findymail 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 Findymail 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

Findymail and Arc0, answered.

Q01

Can I use Findymail with Claude, ChatGPT or Cursor?

Yes. Connect Findymail 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 Findymail actions you allow.

Q02

How do users connect Findymail?

Users add their Findymail 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 Findymail actions can my agent take?

21 in total: 13 read, 5 write and 3 destructive, such as “create Contact List”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Findymail?

Yes. Actions like “delete Contact List” 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 Findymail too?

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