pagesnap

pagesnap lets an agent turn any public web page into a picture. Give it a URL and it renders the page in Chromium upstream and hands back the screenshot — as a viewport capture or as the whole scrollable page, in webp, jpeg or png, at the viewport size you ask for. You can hold the capture until a selector appears, pick which navigation event to wait for, and set the time zone and locale the page sees, which matters when a site renders differently by region or language. A second tool reports how many screenshots you have left, so a workflow can check its allowance before it starts spending it.

This package renders nothing itself. It is a thin local bridge to the hosted snap service: it answers the tool list locally, exactly as captured from the live endpoint, and forwards each call upstream, returning whatever comes back untouched. The service is free without signup; supplying your own API key raises the allowance from the free daily amount to your organisation's monthly amount, which is what get_quota then reports.

Tools

• take_screenshot — render a public web page and return a screenshot. Required: url (a public http(s) URL). Optional: format (webp, jpeg or png, default webp — webp and jpeg are much smaller than png), width (viewport width in CSS pixels, default 1280) and height (default 720; values above the service maximum are clamped), fullPage (capture the full scrollable page, default false), waitUntil (load, domcontentloaded or networkidle, default load), waitForSelector (a CSS selector that must appear before capturing), timezoneId (an IANA time zone such as Europe/Berlin) and locale (a BCP 47 locale such as de-DE). Very tall full-page captures come back as a link instead of an inline image, and a fullPage WebP capture of a page taller than 16383px is clipped to that height (reported as fullPageClip) — use jpeg or png for pages that tall.
• get_quota — how many screenshots are left. Takes no arguments. Returns the free daily allowance when no key is in play, or the organisation's monthly allowance when one is. This tool only reads your own allowance; nothing in this package buys, tops up or manages an account.

Configuration

• SNAP_MCP_URL (optional) — override the upstream endpoint. Defaults to https://snap.i2dev.com/mcp. (The override hook is this rebuild's own labelled reconstruction.)
• SNAP_API_KEY (optional) — when set, every upstream request carries an Authorization: Bearer <key> header with your snap API key. When it is not set, no key header is sent and the free allowance applies. (The header name is pinned by the original's registry record, which declares a secret Authorization header; the record pins no package env name, so the env name, the Bearer form and the forwarding itself are labelled reconstructions — the original surface was captured keyless.)

Forwarding mechanics

On the first tool call the client opens a streamable HTTP session upstream: a JSON-RPC initialize request (protocolVersion 2025-03-26, clientInfo name pagesnap), then a notifications/initialized notification, then the tools/call request carrying the caller's arguments unchanged. When the upstream answers initialize with an Mcp-Session-Id header, that value rides on every later request of the session, which is reused for the life of the process. Replies may arrive as plain JSON or as server-sent events; both are read.

Successful upstream results pass through verbatim, including any isError flag the upstream sets. Failures — a JSON-RPC error, a non-2xx status, an unreadable response, or a request that cannot be completed — come back as an isError result whose text starts with pagesnap error: (this rendering is this rebuild's own labelled reconstruction).

CLI

Each tool is also a subcommand taking one JSON argument string:
