3. chrome_fill_or_select(selector: "#password", value: "...")
4. chrome_click_element(selector: "button[type=submit]")

Search History

Extract Content

User: "What does this page say about pricing?"

AI uses:

Advantages Over Playwright

Multi-Client Support

Multiple AI clients can connect simultaneously:

• Claude Code
• Cursor
• Kiro
• Any MCP-compatible client

Each client gets its own session while sharing the same Chrome browser.

Troubleshooting

Extension Not Connecting

1. Check extension is enabled in chrome://extensions/
2. Click extension icon → Verify "Connected" status
3. Restart Chrome if needed

Port Already in Use

The server automatically handles port conflicts. If issues persist:

lsof -i :12306
kill <PID>
