Hello everyone! Today I want to introduce you to a super cool new tool - Agent TARS App! ?

 What is Agent TARS?

Agent TARS is an open-source multimodal AI agent that can visually interpret web pages and perform smooth browser operations, while also being easily integrated with the command line and file system.

Imagine an intelligent assistant that can help you plan tasks, perform operations, and display results in real time. Isn’t it exciting?

Core Features Highlights

1.  Intelligent workflow orchestration

Agent TARS uses an advanced agent framework to create intelligent workflows to help you complete task planning and execution.

Whether it's searching, browsing the web, or exploring links, it can do it easily, and seamlessly connect with the user interface through event streams, ultimately synthesizing information and outputting results.

2.  Comprehensive tool support

Whether it is complex browser tasks, file editing, or command line operations, Agent TARS can handle it with ease. It integrates with various tools through the Model Context Protocol (MCP), allowing you to easily handle complex workflows with the help of AI.

3.  Real-time interactive experience

Agent TARS App provides an intuitive streaming user interface that allows you to see multimodal "products" in real time, such as browser pages and documents. You can also interact with Agent TARS at any time through the input box, and even insert your ideas while it is working to guide its direction of action.


Technical principles of Agent TARS

  • Agent Framework: Create workflows based on complex agent frameworks to support task planning and execution. Decompose complex tasks into multiple subtasks and interact with the user interface based on event streams. Support Agent TARS to efficiently manage the execution order and dependencies of tasks and realize automated workflows.


  • Model Context Protocol: MCP integrates seamlessly with a variety of tools, including search, file editing, command line, and coding tools. MCP provides a standardized way to manage the model context and tool interaction, allowing Agent TARS to flexibly call and integrate different tools to complete complex tasks.

  • Browser Automation: Use browser automation technology to enable web browsing and interaction. Visually interpret web content, extract key information, perform complex web tasks such as deep research and information extraction, and efficiently process web content without human intervention.

  • Event stream: Interact with the user interface based on the event stream to update the task status and results in real time. The event stream mechanism ensures that users can see the agent's work progress in real time and better understand and control the execution process of the task.

Models can now also be deployed on Volcano Engine
