pi-browser-use is a pi-coding-agent extension that wraps chrome-devtools-mcp, exposing all browser automation tools with a unified browser_ prefix.

License: Apache-2.0


Features

  • Dynamic tool discovery — auto-proxies all upstream chrome-devtools-mcp tools with browser_ prefix
  • Tool description augmentation — adds usage hints for key tools
  • Result post-processing — strips embedded snapshots, detects overlay/stale element issues
  • Optional visual analysis — browser_analyze_screenshot via configurable vision model
  • Standalone mode — runnable as independent MCP server via CLI

Requirements

Node.js >= 20, Chrome (stable or newer), @earendil-works/pi-coding-agent >= 0.74.0.


Installation

pi install npm:@amaster.ai/pi-browser-use

Usage

Auto-discovers and loads on session_start. Configure in .pi/settings.json:

{
  "pi-browser-use": {
    "headless": true,
    "channel": "stable",
    "viewport": "1280x720",
    "experimentalVision": true
  }
}

As Standalone MCP Server

npx @amaster.ai/pi-browser-use --headless --viewport=1280x720

Configuration

Session Mode

Vision Model

{
  "pi-browser-use": {
    "visionModel": {

      "model": "gpt-4o"
    }
  }
}

Resolves API key and base URL from the model registry automatically.


Key Tools

Tool Hint
browser_click Use element uid from snapshot; UIDs invalidated after action
browser_fill Does not work on canvas/custom widgets
browser_press_key Accepts single key name only
browser_take_snapshot Call first to get uids, and after every state-changing action
