Website Screenshot Skill

Overview

A website screenshot and screen capture API. Web Screenshots works by using a headless browser to load the web page and capture a screenshot of the entire page or a specific element. It returns the screenshot as an image. This runs entirely in the cloud, so you don't need to worry about setting up a browser or infrastructure.

The tool

Once your client is connected to the VerveKit server, this appears in its tool list as WebsiteScreenshotSkill. It is read-only and open-world — it fetches and never mutates anything on your side — so most clients call it without asking you to confirm.

Tool call

{
  "name": "WebsiteScreenshotSkill",
  "arguments": {
    "url": "https://www.github.com"
  }
}

You do not name the tool yourself; the model picks it. Asking about https://www.github.com in the terms this skill covers is enough for it to reach for WebsiteScreenshotSkill on its own — naming it explicitly also works, and is the way to force the call.

Connecting

One server URL covers every skill in the catalog, including this one. Authorization is OAuth: the client opens a browser once, and there is no key to paste into a config file.

{
  "mcpServers": {
    "vervekit": {
      "url": "https://api.vervekit.com/v1/mcp"
    }
  }
}

Per-client setup — Claude, Cursor, VS Code, ChatGPT — is on the MCP setup page.

Arguments

These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made. Premium arguments are accepted on every plan but only take effect on plans that include them.

Argument	Type	Description
`url`Required	string	The URL of the web page to capture the screenshot (e.g., https://example.com) url
`type`Optional	string	The image format for the screenshot `pngjpegwebp` default png
`width`Optional	number	The width of the screenshot in pixels (e.g., 1920). Must be between 100 and 3840 default 1920 · range 100–3840
`height`Optional	number	The height of the screenshot in pixels (e.g., 1080). Must be between 100 and 3840 default 1080 · range 100–3840
`fullpage`OptionalPremium	boolean	Whether to capture the full page screenshot (true or false)

What the model gets back

The result carries a structuredContent object matching the tool's declared outputSchema, so a client reads fields without parsing prose. status is "ok" and error is null on success; a null field means the value was not available for that input, not that the call failed.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Field	Type	Example	Description
`width`Premium	number	`1024`	Actual width of captured screenshot in pixels
`height`Premium	number	`600`	Actual height of captured screenshot in pixels
`scaleFactor`Premium	number	`1`	Device pixel ratio used for screenshot capture
`imageName`	string	`77072426-6af8-45c2-93dd-d7013d2c765e.png`	Unique identifier for the generated screenshot image file
`expires`	number	`1766097105719`	Unix timestamp when the screenshot will expire
`url`	string	`https://ebay.com/`	Original URL that was screenshotted
`downloadURL`	string	https://storage.googleapis.com/apiverve-helpers.appspot.com/webscreenshots/77072426-6af8-45c2-93dd-d7013d2c765e.png?GoogleAccessId=1089020767582-compute%40developer.gserviceaccount.com&Expires=1766097105&Signature=uZKa777XpeVnlwOZG7Uhjs%2BNkPzkEuiV4Wug2%2B%2BAHcPovRZ3iVjZEX%2FZhp7gnADXI6au5q0ggPwweoOFJeMCdk9zod6aZo4hlUDe1DsJf0oao4rh3tGUl5wPeudXLp7Y%2F3zVflup9Mp255LY6%2B2JdU0auOHdPnEYLDCvf705X9C%2BflmWQZKh7QKi74gvU8pqsP6Zc7SfJJsv5kmhP8SkO7TBZKBU6pAr2mNHKpKgB5mtfCRLbyPYcxawSGlTuyIyRXffWbkfHdDl6pquPX9J%2Fp5uGYM4jTrqrrrR1MPAOfkD7d9V5juqe5A7VvWmhiAyCMGDO%2BeqUO%2BSe6t9php0vA%3D%3D	Temporary signed URL to download the screenshot image

Failure modes

Errors come back as tool errors carrying a sentence the model can act on, not a bare status code. Error handling covers the full list.

Status	What it means
`400` / `422`	The arguments did not validate. The message names the offending one.
`401`	The OAuth session is invalid or expired — reconnect the server.
`403`	Blocked by a key restriction or an IP allow-list. Never a bad identity.
`404`	This skill is not part of VerveKit. Check the catalog.
`429`	Out of credits, or a brief rate limit. The message tells them apart.

A call costs 40 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.

Use cases

Visual Link Previews: Bookmarking tools generate visual card thumbnails by passing target URLs and saving the returned image download link.
Compliance Web Archiving: To preserve legal records, compliance teams request timestamped JPEG captures of corporate policy pages before contract renewals.
Competitor Landing Tracking: Track layout changes across competitor websites by periodically storing rendered page images and comparing viewport snapshots.
Bug Report Attachments: When testers submit issue tickets, QA dashboards fetch snapshot images of reported URLs to document live rendering bugs.
