live.grabbit由 grabbit.live 发布官方发布者v1.0.2更新于 Oct 27, 2026

Grabbit gives AI agents eyes on the web. Send a public URL, get a pixel-perfect hosted image.

已验证Streamable HTTP可网页运行网页搜索与抓取浏览器自动化

概览

AI 生成的概览

Grabbit 是托管式截图服务，让助手无需本地浏览器即可把任意公开网址截取为托管图片。

可以做什么
  • 截取公开网址并返回内嵌图片及剩余额度
  • 按 id 取回历史截图，浏览最近的截图记录
  • 查询额度、套餐与 30 天用量，并查看定价及带日期的竞品对比
适用场景
适合助手需要查看或展示网页外观的场景，尤其是带 Cookie 同意弹窗、大量 JavaScript、整页布局，或被本地无头浏览器拦截的网站。
运行要求
远程 Streamable HTTP 端点 mcp.grabbit.live，无需本地运行时。必须认证：OAuth 2.1 浏览器登录或 Bearer API 密钥，Codex 配置从环境变量 GRABBIT_API_KEY 读取密钥。实际截图需要预付费额度的付费账户。
安装前请注意
每次实际截图按 0.002 美元从预付费额度中扣费，助手使用会产生费用。私有和内部地址（含 localhost）被 SSRF 防护拦截，部分有严格 IP 封锁的网站仍会失败。服务在其自有基础设施上抓取网址，所请求的网址会发送给第三方。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Grabbit，将其添加到工作区。
  2. 连接 所需的 凭据。它们会被私密存储，绝不会在公开页面上展示。
  3. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/live.grabbit%2Fscreenshots/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

其他 MCP 客户端

把它添加到你客户端的 mcpServers 配置中。 客户端会在首次连接时完成 OAuth 登录。

README

Point your agent at a URL and get back a hosted image, with no local headless browser to run. Grabbit handles cookie and consent banners, JavaScript-heavy and full-page captures, and many sites that block a local browser.

Why a hosted screenshot tool

Most agents can already drive a headless browser. It works on simple pages and quietly fails on the ones that matter: cookie and consent walls, bot detection, login and paywall gates, and heavy client-rendered pages. Grabbit runs the capture on hosted infrastructure, so the shot comes back clean and the agent needs no browser of its own.

Honest bound: no service captures literally every site. A few hard targets behind aggressive IP blocking still resist. Private and internal addresses (including localhost) are blocked by SSRF protection.

Quick start

Claude Code

bash
claude mcp add --transport http grabbit https://mcp.grabbit.live

Then run /mcp and authenticate in the browser (OAuth, no key to paste). Guide: https://grabbit.live/agents/claude-code

Cursor

~/.cursor/mcp.json (commit a project-scoped .cursor/mcp.json to share with your team):

json
{ "mcpServers": { "grabbit": { "url": "https://mcp.grabbit.live" } } }

Guide: https://grabbit.live/agents/cursor

OpenAI Codex

~/.codex/config.toml:

toml
[mcp_servers.grabbit]url = "https://mcp.grabbit.live"bearer_token_env_var = "GRABBIT_API_KEY"

Guide: https://grabbit.live/agents/codex

OpenClaw

Add the hosted MCP server, or wrap the one-line CLI in a skill. Guide: https://grabbit.live/agents/openclaw

Cursor Marketplace

Install Grabbit directly from the Cursor Marketplace (when listed), or add manually:

~/.cursor/mcp.json (or project-scoped .cursor/mcp.json):

json
{ "mcpServers": { "grabbit": { "url": "https://mcp.grabbit.live" } } }

This repo includes Cursor plugin packaging (.cursor-plugin/plugin.json, mcp.json, skill) for marketplace submission.

Agent Skills

This repo ships a portable skill folder (skills/grabbit-screenshots/) that teaches agents when and how to use the Grabbit hosted screenshot MCP.

Install via skills.sh

bash
npx skills add BrainGridAI/grabbit-mcp --skill grabbit-screenshots

After public installs, the skill can appear on skills.sh via install telemetry (no separate submit form).

Publish to ClawHub

From the repo root:

bash
clawhub skill publish ./skills/grabbit-screenshots --slug grabbit-screenshots --name "Grabbit Screenshots" --version 1.0.0

Install via OpenClaw / Hermes

The skill is published on ClawHub at https://clawhub.ai/braingrid/skills/grabbit-screenshots

bash
openclaw skills install @braingrid/grabbit-screenshots# orclawhub install grabbit-screenshots

Hermes can install the same ClawHub skill (ClawHub is a Hermes skill source) and connect MCP at https://mcp.grabbit.live.

CLI

bash
npx grabbit.live login        # browser sign-in, keys saved locallynpx grabbit.live nyt.com      # screenshot a URL, hosted image backnpx grabbit.live mcp          # print MCP config for your agent

Pricing

Flat $0.002 per live capture. Prepaid credits that never reset or expire. Test keys return free placeholders so you can wire it up before paying. Full pricing and the comparison table: https://grabbit.live/#pricing
