概覽

AI 產生的概覽

SnapRender 的本機 stdio MCP 伺服器,讓助理把網頁擷取成圖片或 PDF、擷取頁面內容,並管理截圖批次作業與 Webhook。

可以做什麼
  • 將網址擷取為 PNG、JPEG、WebP 或 PDF,支援裝置預設、整頁、深色模式與選擇器選項
  • 查詢截圖是否已快取,並讀取本月用量與配額
  • 產生無需 API 金鑰即可渲染的簽章截圖連結
  • 以 markdown、文字、HTML、正文、連結或中繼資料形式擷取頁面內容
  • 執行最多 50 個網址的背景批次作業,並輪詢狀態與下載連結
  • 列出、建立、刪除與測試 Webhook 訂閱
適用情境
適合助理需要檢視或封存公開網頁、把頁面轉成易讀的 markdown,或一次擷取大量網址用於報告與比較的情境。若不想在本機執行,也可改用提供相同工具的託管遠端伺服器。
執行需求
透過 npx 在本機執行,需要 Node.js。需要 SnapRender API 金鑰,透過 SNAPRENDER_API_KEY 環境變數提供;有每月 200 張截圖的免費方案。需要能連線至 SnapRender 服務的網路。
安裝前請注意
API 金鑰是有效金鑰,經環境變數傳入,請勿放入共用設定。截圖會消耗每月配額:截圖、簽章連結被開啟、內容擷取以及批次中的每個網址都計為一次截圖。Webhook 工具會建立、刪除訂閱並向外部端點傳送測試資料。頁面網址與選項會傳送至 SnapRender 伺服器。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 SnapRender,將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Desktop only,透過 STDIO。 STDIO 服務會啟動本機處理程序,因此需要 SourceWeft 桌面主機。

SnapRender Integrations

[SnapRender MCP connector: tool definition quality and endpoint health on Glama] [smithery badge] [npm MCP] [npm SDK] [PyPI SDK] [License: MIT] [Available on CodeGuilds] [MCP Badge]

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: Bearer or X-API-Key header
  • 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:

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

Any MCP client (curl)

bash
# Initialize a sessioncurl -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:

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

See mcp-server/ for full documentation.
