Esputnik for AI agents

eSputnik is a marketing automation platform for managing email, SMS, web push, and mobile push campaigns from one contact base. 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.

await arc0.policies.set('esputnik', {
  read: 'allow',
  write: 'ask',        // create_api_token

04 · AUTH AND DATA

How Esputnik connects.

Users add their Esputnik 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 Esputnik 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

Esputnik and Arc0, answered.

Q01

Can I use Esputnik with Claude, ChatGPT or Cursor?

Yes. Connect Esputnik 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 Esputnik actions you allow.

Q02

How do users connect Esputnik?

Users add their Esputnik 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 Esputnik actions can my agent take?

89 in total: 35 read, 38 write and 16 destructive, such as “create API Token”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Esputnik?

Yes. Actions like “delete Orders” 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 Esputnik too?

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