Heyreach for AI agents

HeyReach is a multichannel outreach platform for engaging prospects across LinkedIn and other channels at scale. Marketers fold it into their existing outreach and campaign workflow instead of running it separately. 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 Heyreach connects.

Users add their Heyreach 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 Heyreach 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

Heyreach and Arc0, answered.

Q01

Can I use Heyreach with Claude, ChatGPT or Cursor?

Yes. Connect Heyreach 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 Heyreach actions you allow.

Q02

How do users connect Heyreach?

Users add their Heyreach 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 Heyreach actions can my agent take?

19 in total: 13 read, 5 write and 1 destructive, such as “create Tags”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Heyreach?

Yes. Actions like “delete Webhook” 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 Heyreach too?

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