Overview

The browser tool provides web browsing capabilities to your agent. It can navigate to URLs, interact with page elements, extract content, and take screenshots. This is powered by a headless browser (Playwright) running on the host system.

​
Capabilities

ActionDescription
navigateOpen a URL in the browser
clickClick on an element
typeType text into an input field
extractExtract text content from the page
screenshotTake a screenshot of the page
scrollScroll the page
waitWait for an element or condition

​
Usage Examples

The agent can browse a website and extract relevant information: 
{
  "tool": "browser",
  "input": {
    "action": "navigate",
    "url": "https://news.ycombinator.com"
  }
}
Followed by: 
{
  "tool": "browser",
  "input": {
    "action": "extract",
    "selector": ".titleline"
  }
}

​
Form Interaction

{
  "tool": "browser",
  "input": {
    "action": "type",
    "selector": "#search-input",
    "text": "ArgentOS documentation"
  }
}

​
Configuration

{
  "agents": {
    "defaults": {
      "browser": {
        "headless": true,
        "timeout": 30000,
        "viewport": { "width": 1280, "height": 720 }
      }
    }
  }
}

​
Prerequisites

The browser tool requires Playwright to be installed: 
npx playwright install chromium

​
Security Considerations

The browser runs with the same permissions as the ArgentOS process. Be cautious with agents that have both browser and exec tools — they can be powerful in combination.
  • Consider restricting allowed domains in production environments
  • Cookie and session data persists between browser actions within a session

​
Limitations

  • Browser state does not persist across gateway restarts
  • JavaScript-heavy SPAs may require explicit wait conditions
  • File downloads through the browser require separate handling
  • The browser runs headless by default; there is no visual UI to observe
