User Tests Command Code macOS App: Agent Builds Its Own Computer Use via UI-TARS MCP

Key Info

A user reports that the new Command Code macOS app (released yesterday) had no built-in "Computer Use" feature, so they prompted it to use an open-source tool (DeepSeek 4.1 Flash) to add that capability. The agent created an MCP server for UI-TARS, wrote its own computer-use functionality, and it is now working smoothly.

Highlights

• Command Code autonomously created an MCP server for UI-TARS to gain computer-use abilities.
• The resulting computer-use feature reportedly works well, though it is slower than Codex and Claude.
• The user highlights the extremely low cost as a major advantage.
