Browser Automation

Minimal Chrome DevTools Protocol (CDP) helpers for browser automation without MCP server setup.

Setup

Install dependencies before first use:

npm install --prefix ~/.claude/skills/browser/browser ws

Scripts

All scripts connect to Chrome on

localhost:9222

start.js - Launch Chrome

scripts/start.js              # Fresh profile
scripts/start.js --profile    # Use persistent profile (keeps cookies/auth)

nav.js - Navigate

scripts/nav.js https://example.com        # Navigate current tab
scripts/nav.js https://example.com --new  # Open in new tab

eval.js - Execute JavaScript

scripts/eval.js 'document.title'
scripts/eval.js '(() => { const x = 1; return x + 1; })()'

Use single expressions or IIFE for multiple statements.

screenshot.js - Capture Screenshot

scripts/screenshot.js

Returns

{ path, filename }

of saved PNG in temp directory.

pick.js - Visual Element Picker

scripts/pick.js "Click the submit button"

Returns element metadata: tag, id, classes, text, href, selector, rect.

Workflow

Launch Chrome:
```
scripts/start.js --profile
```
for authenticated sessions
Navigate:
```
scripts/nav.js <url>
```

Inspect:

scripts/eval.js 'document.querySelector(...)'

Capture:
```
scripts/screenshot.js
```
or
```
scripts/pick.js
```
Return gathered data

Key Points

All operations run locally - credentials never leave the machine
Use
```
--profile
```
flag to preserve cookies and auth tokens
Scripts return structured JSON for agent consumption
