Grabbit

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.

Endpoint	https://mcp.grabbit.live (Streamable HTTP)
Auth	OAuth 2.1 (claude.ai connectors work out of the box) or a Bearer API key
Registry name	live.grabbit/screenshots
Setup guides	https://grabbit.live/agents

Tools

Tool	What it does
grab	Screenshot any public URL and get a hosted image back (inline image + remaining credits)
get_grab	Fetch a previous capture by id
list_grabs	Browse your recent captures
get_usage	Credits, plan, and 30-day usage
get_pricing	Pricing plus an honest, dated comparison against ScreenshotOne, Urlbox, Browserless, and others

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

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):

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

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

OpenAI Codex

~/.codex/config.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):

{ "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

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:

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

openclaw skills install @braingrid/grabbit-screenshots
# or
clawhub 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

npx grabbit.live login        # browser sign-in, keys saved locally
npx grabbit.live nyt.com      # screenshot a URL, hosted image back
npx 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
