Engage Platform for AI agents

Engage Platform provides customer data, list, and event APIs for building transactional and lifecycle messaging workflows, used by product and growth teams triggering messages off user behavior. 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 Engage Platform connects.

Users add their Engage Platform 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 Engage Platform 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

Engage Platform and Arc0, answered.

Q01

Can I use Engage Platform with Claude, ChatGPT or Cursor?

Yes. Connect Engage Platform 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 Engage Platform actions you allow.

Q02

How do users connect Engage Platform?

Users add their Engage Platform 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 Engage Platform actions can my agent take?

18 in total: 6 read, 8 write and 4 destructive, such as “create List”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Engage Platform?

Yes. Actions like “delete User Attribute” 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 Engage Platform too?

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