JS Eyes

Browser extension + WebSocket server that gives AI agents full browser automation capabilities.

What it does

JS Eyes connects a browser extension (Chrome / Edge / Firefox) to an AI agent framework via WebSocket, enabling the agent to:

• List and manage browser tabs
• Open URLs and navigate pages
• Extract full HTML content from any tab
• Execute arbitrary JavaScript in page context
• Read cookies for any domain
• Monitor connected browser clients

Architecture

Browser Extension  <── WebSocket ──>  JS-Eyes Server  <── WebSocket ──>  AI Agent (OpenClaw)
 (Chrome/Edge/FF)                     (Node.js)                         (Plugin: index.mjs)

The browser extension runs in the user's browser and maintains a persistent WebSocket connection to the JS-Eyes server. The OpenClaw plugin connects to the same server and exposes 7 AI tools + a background service + CLI commands.

Provided AI Tools

Tool	Description
js_eyes_get_tabs	List all open browser tabs with ID, URL, title
js_eyes_list_clients	List connected browser extension clients
js_eyes_open_url	Open a URL in new or existing tab
js_eyes_close_tab	Close a tab by ID
js_eyes_get_html	Get full HTML content of a tab
js_eyes_execute_script	Run JavaScript in a tab and return result
js_eyes_get_cookies	Get all cookies for a tab's domain

CLI Commands

openclaw js-eyes status          # Server connection status
openclaw js-eyes tabs            # List all browser tabs
openclaw js-eyes server start    # Start the built-in server
openclaw js-eyes server stop     # Stop the built-in server

Plugin Files

This skill bundle contains the OpenClaw plugin source — these are the files OpenClaw needs to load and run the plugin:

File	Role
openclaw.plugin.json	Plugin manifest — ID, description, config schema (JSON Schema) and UI hints for settings
package.json	Node.js package descriptor — declares ESM module type and the plugin entry point
index.mjs	Plugin logic — registers 7 AI tools, 1 background service (WebSocket server) and CLI commands with OpenClaw

index.mjs imports the WebSocket server and client SDK from the parent repository (../server/ and ../clients/), so the full js-eyes repo must be cloned for the plugin to work. This directory alone is not self-contained.

Prerequisites

• Node.js >= 14
• Git
• A supported browser: Chrome 88+ / Edge 88+ / Firefox 58+

Setup

Step 1: Install the browser extension

Download the latest version from GitHub Releases:

• Chrome/Edge: download js-eyes-chrome-vX.Y.Z.zip, open chrome://extensions/ (or edge://extensions/), enable Developer mode, click "Load unpacked" and select the extracted folder
• Firefox: download js-eyes-firefox-vX.Y.Z.xpi, drag and drop into the browser window

Step 2: Clone and install

git clone https://github.com/imjszhang/js-eyes.git
cd js-eyes
npm install

Step 3: Register the plugin in OpenClaw

Edit your OpenClaw config file (~/.openclaw/openclaw.json) and add the plugin:

{
  "plugins": {
    "load": {
      "paths": ["~/projects/js-eyes/openclaw-plugin"]
    },
    "entries": {
      "js-eyes": {
        "enabled": true,
        "config": {
          "serverPort": 18080,
          "autoStartServer": true
        }
      }
    }
  }
}

Replace ~/projects/js-eyes/openclaw-plugin with the actual absolute path to the openclaw-plugin directory inside the cloned repository.

Step 4: Connect the browser extension

1. Start OpenClaw — the built-in WebSocket server launches automatically on port 18080
2. Click the JS Eyes extension icon in the browser toolbar
3. Enter http://localhost:18080 as the server address
4. Click "Connect" — the status should turn green ("Connected")

Step 5: Verify

Run the following CLI command to confirm everything is working:

openclaw js-eyes status

Expected output:

=== JS-Eyes Server Status ===
  Uptime: ...s
  Browser extensions: 1
  Automation clients: ...

You can also ask the AI agent to list your browser tabs — it should invoke js_eyes_get_tabs and return the tab list.

Plugin Configuration

Option	Type	Default	Description
serverHost	string	"localhost"	Server listen address
serverPort	number	18080	Server port (must match extension config)
autoStartServer	boolean	true	Auto-start server when plugin loads
requestTimeout	number	60	Per-request timeout in seconds

Troubleshooting

Symptom	Cause	Fix
Extension shows "Disconnected"	Server not running	Check openclaw js-eyes status; ensure autoStartServer is true
js_eyes_get_tabs returns empty	No extension connected	Click extension icon, verify address is correct, click Connect
Cannot find module 'ws'	Dependencies not installed	Run npm install in the cloned js-eyes directory
Tools not appearing in OpenClaw	Plugin path wrong or not enabled	Double-check the path in plugins.load.paths points to the openclaw-plugin folder
