Connect to a running Chrome instance (must be launched with --remote-debugging-port). Returns the active tab URL and total tab count. Always call this first.

List all open tabs across contexts. Use to find a specific tab to focus.

Switch the active tab by index (from list_tabs) or by URL substring.

Capture the active tab. Returns base64 PNG, URL, title, and any detected handoff triggers (2FA, captcha, payment prompts). Call this after every action to verify state.

Return a numbered list of interactive elements (buttons, links, inputs) from the accessibility tree. Use the returned id with click() or type() — no coordinates needed.

Click by id (from inspect), by visible text, or by CSS selector. Returns {changed: true/false} based on a pre/post screenshot diff — false means the click had no effect.

Type into a field by id (from inspect) or CSS selector. Set submit=true to press Enter after.

Navigate the active tab to a URL.

Wait for visible text or a CSS selector to appear on the page.

Pause and ask the human to complete the next step manually (2FA, payment, sensitive config). Returns a paused state — the human resolves it in the browser, then tells Claude to continue.
