Grok for AI agents

Grok is xAI's API platform for text, image, video, and voice generation, used by developers to add generative AI features to apps. 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

Grok in three steps.

  1. 01Your users connect GrokThey add their Grok api key on Arc0 Connect, under your brand. It goes straight into the vault.
  2. 02You set the rulesReads run, and writes like “create Response” can wait for the user to approve.
  3. 03Any agent can actYour agent calls Grok 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('grok', {
  read: 'allow',
  write: 'ask',        // create_response
  destructive: 'deny',  
})

04 · AUTH AND DATA

How Grok connects.

Users add their Grok 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 Grok 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

Grok and Arc0, answered.

Q01

Can I use Grok with Claude, ChatGPT or Cursor?

Yes. Connect Grok 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 Grok actions you allow.

Q02

How do users connect Grok?

Users add their Grok 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 Grok actions can my agent take?

8 in total: 4 read, 4 write and 0 destructive, such as “create Response”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Grok?

Yes. Allow read actions and deny writes in the Grok policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call Grok too?

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