Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

capture_context

Returns the structured representation of a web page: visible text with coordinates, interactive elements, forms and tables. Use this to let an agent read and understand a page without parsing raw HTML.

urlstring, required

The page to read

widthinteger

heightinteger

dismissCookiesboolean

Auto-dismiss cookie/consent banners before reading. Default true.

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway

create_semantic_monitor

Watches a URL on a schedule and reports what changed and whether it matters, explained by AI — not just a pixel-diff percentage. Use this for competitor pricing pages, changelogs, status pages, or any page whose changes should trigger a workflow.

Argument	Type	Description
url*	string
label	string
intent	string	What you care about, in plain language, e.g. "alert me about pricing or plan changes"
schedule	string	Cron expression, e.g. "/30 * * *". Defaults to every 10 minutes.

find_elements

Returns only the interactive elements of a page (buttons, links, inputs) with role, label, CSS selector and pixel coordinates. Use this before acting on a page (computer-use / Set-of-Marks style grounding) instead of capture_context when you only need to know what can be clicked and where.
