发布方自己的服务:SnapRender

概览

AI 生成的概览

SnapRender 的本地 stdio MCP 服务器,让助手把网页截取为图片或 PDF、提取页面内容,并管理截图批处理与 Webhook。

可以做什么
  • 将网址截取为 PNG、JPEG、WebP 或 PDF,支持设备预设、整页、深色模式与选择器选项
  • 查询截图是否已缓存,并读取本月用量与配额
  • 生成无需 API 密钥即可渲染的签名截图链接
  • 以 markdown、文本、HTML、正文、链接或元数据形式提取页面内容
  • 运行最多 50 个网址的后台批处理,并轮询状态与下载链接
  • 列出、创建、删除和测试 Webhook 订阅
适用场景
适合助手需要查看或归档公开网页、把页面转成可读 markdown,或一次性截取大量网址用于报告和对比的场景。若不想在本地运行,也可使用提供相同工具的托管远程服务器。
运行要求
通过 npx 在本地运行,需要 Node.js。需要 SnapRender API 密钥,通过 SNAPRENDER_API_KEY 环境变量提供;有每月 200 张截图的免费方案。需要能访问 SnapRender 服务的网络。
安装前请注意
API 密钥是有效密钥,经环境变量传入,请勿放入共享配置。截图会消耗每月配额:截图、签名链接被打开、内容提取以及批处理中的每个网址都计为一次截图。Webhook 工具会创建、删除订阅并向外部端点发送测试数据。页面网址与选项会发送到 SnapRender 服务器。

安装

在 SourceWeft 中

  1. 打开 控制台中的 SnapRender,将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only,通过 STDIO。 STDIO 服务会启动本地进程,因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

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.
