Official integrations for SnapRender Screenshot API — capture screenshots of any website as PNG, JPEG, WebP, or PDF.

Remote MCP Server

SnapRender runs a hosted MCP server — connect from any MCP client with zero install:

https://app.snap-render.com/mcp

• Transport: Streamable HTTP (MCP spec 2025-03-26)
• Auth: X-API-Key header or Authorization: Bearer header
• Tools: take_screenshot, check_screenshot_cache, get_usage
• Prompts: screenshot_website, compare_devices

Claude Desktop (remote — recommended)

{
  "mcpServers": {
    "snaprender": {
      "type": "streamable-http",
      "url": "https://app.snap-render.com/mcp",
      "headers": {
        "Authorization": "Bearer sk_live_your_key_here"
      }
    }
  }
}

Any MCP client (curl)

# Initialize a session
curl -X POST https://app.snap-render.com/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "X-API-Key: sk_live_your_key_here" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}'

The server returns an Mcp-Session-Id header — include it in subsequent requests to reuse the session.

Smithery

Install via Smithery for automatic setup with any MCP client.

Local MCP Server (npm)

If you prefer running locally via stdio transport:

{
  "mcpServers": {
    "snaprender": {
      "command": "npx",
      "args": ["-y", "snaprender-mcp"],
      "env": {
        "SNAPRENDER_API_KEY": "sk_live_your_key_here"
      }
    }
  }
}

See mcp-server/ for full documentation.
