Fetch a URL and return clean content — markdown by default, or specific fields via a CSS-selector schema. Tries a plain HTTP fetch first and only launches a browser if the page needs JS to render.

Verify something about a page (text present/absent, element present/absent, exact text match) without returning the whole page — just a pass/fail and a short evidence snippet.

Check whether a page (or a subtree of it) has changed since the last check. Returns changed=true/false and a short snippet — not the full content — so repeated monitoring stays cheap.

Run a sequence of actions (click, fill, select, press, waitFor) on a live page — for testing flows or reaching content behind interaction. Returns a text accessibility snapshot by default; pass screenshot=true only when you actually need to see pixels.

Delete persisted cookies and storageState for a given sessionId.

Perform a BFS crawl starting at startUrl up to maxDepth/maxPages. Returns page titles, link structures, and excerpts, while caching full markdown for web_crawl_get_page.

Fetch cached page content discovered during a web_crawl call.
