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.
What agents do in Heyreach.
Add leads to a campaign list
Add a batch of new leads to an outreach list so they enter the next campaign.

19 Heyreach actions, graded by risk.
Every Heyreach action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

Heyreach in three steps.
- 01Your users connect HeyreachThey add their Heyreach api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, writes like “create Tags” can wait for the user, and “delete Webhook” can be denied outright.
- 03Any agent can actYour agent calls Heyreach through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('heyreach', { read: 'allow', write: 'ask', // create_tags destructive: 'deny', // delete_webhook }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
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 →
- AUTH
- API key
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials
- AUDIT LOG
- Every call, on every plan
Use Heyreach from any agent.
Heyreach and Arc0, answered.
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.
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.
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.
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.
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.
Plug Heyreach into your agent.
Your users connect Heyreach once, under your brand. Your agent gets 19 actions behind your policies, with every call on the record.
