xAI / Grok

Use Grok models with Cua Driver through Grok Build.

Grok Build is xAI's coding agent and supports local MCP servers. It is the shortest verified route from a Grok model to Cua Driver.

Start here when…Recommended path
You use Grok BuildConnect Grok Build to Cua Driver
You are building a custom Grok agentCall Cua Driver through MCP or the CLI
You want to manage the agent from T3 CodeConfigure Grok Build first, then use it through T3 Code

Cua Driver does not call the Grok API directly. Grok Build owns the agent loop and launches Cua Driver as a local tool server.

See xAI's Grok Build overview and MCP server guide.
