Navigate the browser to a local dev URL (validated against the localhost allowlist).

Capture a screenshot of the current page (optionally full page or a single element). Use format 'jpeg' (with optional quality 1-100) for a lighter, faster capture; 'png' (default) is lossless.

Return a flat accessibility/DOM snapshot (tag, role, text, ref) for element targeting. Use a returned ref with browser_click.

Click an element by CSS selector or by a ref from browser_snapshot.

Hover the mouse over an element (by CSS selector or snapshot ref) — e.g. to open a dropdown menu.

Fill an input/textarea identified by a CSS selector with the given value.

Type text using the keyboard into the currently focused element.

Press a key or chord on the keyboard (e.g. "Enter", "Tab", "Escape", "ArrowDown", "Control+A"). Useful to submit forms or navigate without a mouse.

Evaluate a JavaScript expression in the page context and return the JSON-serializable result. On non-local pages this prompts the user for confirmation first.

Return buffered console messages (log/warn/error) captured from the page.

Return recent network requests (method, url, status, resourceType).

Wait for a selector to become visible, for text to appear, or for a short delay.

Resize the page viewport.

Reload the current page.

Navigate back in history.

Navigate forward in history.

Return the visible text content of the page body.

List open tabs (index, url, title, and which is active).

Open a new tab (optionally navigating to a URL) and make it active. Returns the updated tab list.

Switch the active tab by index (see browser_tabs).

Close a tab by index, or the active tab if no index is given. Returns the updated tab list.

Return JS dialogs (alert/confirm/prompt/beforeunload) the page has raised, and how each was handled.

Set how JS dialogs are auto-handled: 'accept' (default) or 'dismiss'. beforeunload is always dismissed.

List files downloaded during this session (url, filename, saved path).

List the hosts the browser may navigate to, and whether all hosts are allowed.

Request permission to add a host (e.g. "github.com") to the navigation allowlist. The user is asked to approve; returns whether it was granted.

Remove a host from the navigation allowlist.
