Documentación

The Model Context Protocol (MCP) lets AI assistants call external tools. Shotkiln's remote MCP server gives Claude Code, Cursor and other clients screenshot, PDF and OG image tools, with or without an API key.

URL

https://shotkiln.com/mcp

Transport

Streamable HTTP (stateless, JSON responses)

Auth

x-api-key header or Authorization: Bearer; optional

Tools

take_screenshot, render_pdf, generate_og_image

Returns

images as MCP image content; PDFs as embedded resources

Limits

your plan's limits; anonymous: 3/minute, 10/day

Add it to Claude Code

claude mcp add --transport http shotkiln https://shotkiln.com/mcp \
  --header "x-api-key: $SHOTKILN_KEY"

Then ask, for example, "Take a full-page screenshot of example.com at 390 px wide and describe the layout."

Add it to Cursor

Add this to ~/.cursor/mcp.json or the project's .cursor/mcp.json:

{
  "mcpServers": {
    "shotkiln": {
      "url": "https://shotkiln.com/mcp",
      "headers": { "x-api-key": "YOUR_KEY" }
    }
  }
}

Clients that only support stdio

Bridge the remote server to stdio with mcp-remote:

{
  "mcpServers": {
    "shotkiln": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://shotkiln.com/mcp", "--header", "x-api-key:YOUR_KEY"]
    }
  }
}

Frequently asked questions

What is an MCP screenshot server?

An MCP screenshot server gives an AI assistant a tool that captures web pages and returns the image. Shotkiln runs a remote one, so there's nothing to install.

Does it work without an API key?

Yes, on the anonymous limits of 3 watermarked renders a minute and 10 a day. Add an x-api-key header in your client config to use your plan.

Which MCP clients are supported?

Any client with remote Streamable HTTP support, including Claude Code, Cursor and the MCP Inspector. Stdio-only clients connect through the mcp-remote bridge.

Why does SSRF protection matter for agents?

Text on a web page can talk an agent into fetching an internal URL such as 169.254.169.254. Shotkiln refuses private and metadata addresses on every request, redirect and subrequest.

Can the agent read the text of the page?

Only visually: the tools return images and PDFs, and multimodal models read the text in them. Treat that text as untrusted input, since a page can show instructions aimed at the agent. For plain text, add a scraping tool.
