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

已驗證Streamable HTTP可網頁執行網頁搜尋與抓取瀏覽器自動化

概覽

AI 產生的概覽

Grabbit 是託管式截圖服務，讓助理不必在本地執行瀏覽器，就能把任何公開網址截成託管圖片。

可以做什麼
  • 截取公開網址並回傳內嵌圖片與剩餘額度
  • 依 id 取回先前的截圖，瀏覽最近的截圖紀錄
  • 查詢額度、方案與 30 天用量，並查看定價及附日期的競品比較
適用情境
適合助理需要查看或展示網頁外觀的情況，尤其是含 Cookie 同意橫幅、大量 JavaScript、整頁版面，或被本地無頭瀏覽器擋下的網站。
執行需求
遠端 Streamable HTTP 端點 mcp.grabbit.live，不需本地執行環境。必須驗證：OAuth 2.1 瀏覽器登入或 Bearer API 金鑰，Codex 設定會從環境變數 GRABBIT_API_KEY 讀取金鑰。實際截圖需要具備預付額度的付費帳號。
安裝前請注意
每次實際截圖依預付額度計費 0.002 美元，助理使用會產生費用。私有與內部位址（含 localhost）會被 SSRF 防護阻擋，部分採嚴格 IP 封鎖的網站仍會失敗。服務在自己的基礎設施上抓取網址，所請求的網址會傳送給第三方。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Grabbit，將其新增到工作區。
  2. 連接 所需的 憑證。它們會被私密儲存，絕不會在公開頁面上展示。
  3. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/live.grabbit%2Fscreenshots/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

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
