ByteDance's open multimodal agent stack — vision-grounded computer-use, callable from Claude via MCP.
UI-TARS Desktop is ByteDance's open multimodal agent platform. It uses screen understanding for desktop control and exposes itself as MCP. Claude can delegate vision-grounded GUI tasks where text-only tools fall short.
