Zernio for AI agents

Zernio manages social media scheduling, analytics, and inbox conversations across many platforms, used by social teams running one workflow instead of one per network. 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.

03 · HOW IT WORKS

Zernio in three steps.

  1. 01Your users connect ZernioThey sign in to Zernio on Arc0 Connect, under your brand, and approve the access you ask for.
  2. 02You set the rulesReads run, writes like “call tool” can wait for the user, and “posts delete” can be denied outright.
  3. 03Any agent can actYour agent calls Zernio through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
POLICY.TS
await arc0.policies.set('zernio', {
  read: 'allow',
  write: 'ask',        // call_tool
  destructive: 'deny',  // posts_delete
})

# Claude Code: the same connection, one URL

04 · AUTH AND DATA

How Zernio connects.

Zernio runs its own MCP server behind OAuth. Arc0 registers the client, users approve access on Arc0 Connect, and your agent reaches Zernio through the same endpoint, policies and audit log as every other app.

The same Zernio 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

Zernio and Arc0, answered.

Q01

Can I use Zernio with Claude, ChatGPT or Cursor?

Yes. Connect Zernio 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 Zernio actions you allow.

Q02

How do users connect Zernio?

Zernio runs its own MCP server behind OAuth. Arc0 registers the client, users approve access on Arc0 Connect, and your agent reaches Zernio through the same endpoint, policies and audit log as every other app.

Q03

Which Zernio actions can my agent take?

52 in total: 4 read, 44 write and 4 destructive, such as “call tool”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Zernio?

Yes. Actions like “posts delete” 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 Zernio too?

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