MCP TOOLcubeshell.web.screenshot

Web Screenshot

Captures one exact public page as PNG, JPEG, or WebP. It does not search, sign in, accept cookies, or perform interactive browser actions.

Price

A successful valid screenshot costs 7.50 Cubeshell credits. A definitive failure is not charged. Cubeshell returns the image and exact receipt together.
