SnapRender Integrations
Official integrations for the SnapRender Screenshot API: give AI agents eyes. Capture any public web page as PNG, JPEG, WebP or PDF, or read it as clean markdown.
Remote MCP Server (recommended)
SnapRender runs a hosted MCP server. Connect from any MCP client with nothing to install:
https://app.snap-render.com/mcp
- Transport: Streamable HTTP
- Sign in: OAuth 2.0 (the client opens a SnapRender sign-in window; Google, GitHub or email), or an API key in the
Authorization: BearerorX-API-Keyheader - Tools (11): capture, cache check, usage, signed links, content extraction, batches and webhooks (full list below)
- Prompts:
screenshot_website,compare_devices - Free plan: 200 screenshots a month, no credit card
- Directory listing: SnapRender on Glama (health-checked, tool quality graded)
Claude (claude.ai and Claude Desktop)
Open Customize, then Connectors, click + Add, then Add custom connector, and paste https://app.snap-render.com/mcp. Claude opens a SnapRender sign-in window; approve it and the tools are ready. Step-by-step guide: snap-render.com/claude.
Cursor, VS Code, Windsurf and other clients
Setup pages for each client, with one-click install where the client supports it: snap-render.com/ai-connectors.
A client that takes headers instead of OAuth:
{
"mcpServers": {
"snaprender": {
"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 later 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.
