The MCP server
Nine tools that let a local agent list your tabs, capture one, read a page's design, scan how it scrolls, and check its quotes against the capture.
@page-scanner/mcp is a stdio MCP server with nine tools: install, pair, list_browsers,
list_tabs, scan_page, diff_captures, extract_design, storyboard_page and check_quotes.
An agent on your machine can list the tabs you have open, capture one, get the file written to
disk, later say what changed on the page since, read the design a page is drawn with as tokens,
scan how a page behaves as it scrolls, and check that what it quotes from a page is in the
capture as written.
It holds no logic of its own. Everything below it is the
@page-scanner/cli package, which owns the loopback listener, the pairing and the
daemon, so the command line and an agent can be used at the same time.
