Browser & web

Use direct fetch for static content and browser automation only when navigation, JavaScript, authentication, or interaction requires a real page.

HTTP reads

fetch_url returns the requested response. fetch_readable_url extracts bounded reader-oriented content. Network output remains subject to size limits and artifact spill.

Tabs and actions

browser_tabbrowser_actionbrowser_screenshot

Tabs have stable handles. Actions navigate, observe, select, click, type, scroll, extract, and wait against the current document state. Navigation invalidates stale element references.

Visible and headless

Interactive

/browser status
/browser headless
/browser visible

Visible mode is appropriate when an operator must observe or complete an authentication step. Screenshots verify appearance; accessibility or DOM extraction verifies structure and state.
