Site-Shot MCP server

Give Claude, Cursor, and other AI agents the ability to see any web page — take website screenshots with Site-Shot over the Model Context Protocol.

Real Chromium rendering · full-page capture · country proxies · automatic ad & cookie-banner removal (cleaner images, fewer vision tokens).

Quick start (Claude Desktop)

Get a Site-Shot API key at https://www.site-shot.com/start/.
Add this to your Claude Desktop config (claude_desktop_config.json):

config.json

{
  "mcpServers": {
    "site-shot": {
      "command": "npx",
      "args": ["-y", "site-shot-mcp"],
      "env": { "SITESHOT_API_KEY": "YOUR_API_KEY" }
    }
  }
}

Restart Claude Desktop. Ask it to "take a full-page screenshot of https://news.ycombinator.com" and it will call the server and show you the image.

Works the same way in any MCP client (Cursor, Cline, VS Code, LangChain, CrewAI) — point the client at npx -y site-shot-mcp with SITESHOT_API_KEY in the environment.

Tools

`capture_screenshot`

Screenshot a web page (viewport by default).

Param	Type	Default	Notes
`url`	string (required)	—	Page to capture
`full_page`	boolean	`false`	Capture the whole scrollable page
`width` / `height`	number	API default	Viewport / device size
`format`	`"png"` \| `"jpeg"`	`png`	Image format
`block_ads`	boolean	`true`	Remove ads
`block_cookie_banners`	boolean	`true`	Remove cookie-consent popups
`country`	string	—	Proxy country as a two-letter ISO 3166-1 alpha-2 code, e.g. `"DE"` (auto IP/lang/tz/geo)
`strict_country`	boolean	`true`	Error out if the country has no proxy, instead of falling back to the US
`language` / `time_zone` / `geolocation`	string	—	Manual overrides
`wait_ms`	number	API default	Extra wait before capture (SPAs/animations)
`max_height`	number	20000 (full page)	Cap captured height

Returns the screenshot as an MCP image.

"API default" is not a number this package gets to state. width, height and wait_ms are forwarded only when you pass them, so whatever applies when you don't is decided by the Site-Shot API and can change without a release here. Versions up to 1.1.0 printed pixel sizes for width / height that the API does not use — an agent that omitted them to take "the default" got a different viewport, with nothing in the returned image to reveal it. Pass explicit values whenever the size matters.

Country codes are ISO codes, never names. Pass "DE", not "Germany". The API matches codes exactly and would otherwise render through a US proxy without telling you, so the server rejects full names before spending a render. strict_country (on by default) likewise turns an unavailable country into an error instead of a silent US screenshot — pass false to opt back into the fallback.

`capture_full_page`

Same as capture_screenshot with full-page capture enabled.

Why call this server instead of the agent's own browser?

If your agent drives a browser, it can screenshot pages itself — and for pages that must be signed into or stepped through a flow, that is the right tool. For public URLs, delegating the capture to this server is usually better engineering: every capture runs the same pipeline (no re-planning between runs), can be taken from a specific country with matching locale and time zone (country + strict_country), is scored by an image classifier with an escalating retry ladder behind it before being returned, and costs a fraction of a cent instead of a browser session plus vision tokens per look. The full comparison, both directions honestly argued: AI agent vs. screenshot API — who should capture the page.

Configuration

Env var	Required	Description
`SITESHOT_API_KEY`	yes	Your Site-Shot API key (used as `userkey`).

The server is a thin wrapper over the existing Site-Shot HTTP API (https://api.site-shot.com/) — no separate backend.

Local development

Terminal

npm install
npm run check   # syntax check
npm run smoke   # offline tests (stubbed fetch, no API key needed)
SITESHOT_API_KEY=yourkey npm start   # run the server on stdio

Requirements

Node.js ≥ 18 (uses the built-in fetch).
