Editor's note
This repository from ByteDance ships two related projects under the TARS umbrella: Agent TARS and UI-TARS Desktop. Agent TARS is a multimodal AI agent accessible via a CLI (`@agent-tars/cli`) and a Web UI, combining GUI automation and vision capabilities with MCP tool integration to handle browser, terminal, and computer tasks. It supports an isolated sandbox execution environment introduced in v0.3.0, along with streaming tool output, timing statistics, and an Event Stream Viewer for debugging. UI-TARS Desktop is a native desktop application built around ByteDance's own UI-TARS vision-language model, offering both local and remote operators for controlling computers and browsers without additional configuration. The stack connects to multimodal LLMs through its own model infrastructure rather than Claude directly, though it exposes MCP server interfaces that make it usable alongside MCP-compatible clients. Developers building GUI automation agents, researchers exploring computer-use workflows, and teams needing scriptable browser or desktop control are the primary audience.
MCP Servers overview
