xAI / Grok
Use Grok Build or Grok Bot with Cua Driver.
Use Grok Build when the agent and Cua Driver run on the same computer. Use Grok Bot when a persistent cloud agent should operate apps on your local computer, or when it should drive Grok Bot's own cloud computer.
| Start here when… | Recommended path |
|---|---|
| You use Grok Build | Connect Grok Build to Cua Driver |
| You use Grok Bot | Let Grok Bot drive local or cloud-computer apps |
| You are building a custom Grok agent | Call Cua Driver through MCP or the CLI |
| You want to manage the agent from T3 Code | Configure Grok Build first, then use it through T3 Code |
Cua Driver does not call the Grok API directly. Grok Build can launch Cua Driver as a local tool server. Grok Bot can invoke the local CLI under its local-computer policy, install Cua Driver on its own cloud computer, or reach an authenticated Streamable HTTP MCP endpoint through a gateway.
