T3 Code

Use Cua Driver from an agent harness managed in T3 Code.

T3 Code is a control plane for coding agents. It runs and organizes harnesses such as Claude Code, Codex, Qwen Code, and Grok Build; it is not itself the MCP client that launches Cua Driver.

To use Cua Driver from T3 Code:

  1. Choose one of T3 Code's supported agent harnesses.
  2. Register Cua Driver in that harness using its page in this section.
  3. Start or restart the harness from T3 Code and confirm the Cua Driver tools are available.

This separation keeps the MCP configuration portable. The same harness can use Cua Driver whether it is launched from T3 Code or directly from a terminal.

Start with Claude Code, OpenAI Codex, Grok Build, or Qwen Code.
