Do I need an API key?

No. You sign in from the browser once and press Approve. Nothing to paste, nothing to rotate.

Which models can I run?

All 91 of them: image, video, audio, 3D and vector. Ask your agent to list the models to see the price of each.

Will my agent spend credit without asking?

The setup prompt tells it to price each run and wait for your yes. Your usage page lists every run and what it cost.

Where do the results go?

Your library at visualsandbox.com. Every result also gets a page you can share.

Can I use more than one of these?

Yes. The CLI, the MCP server, the Claude Code plugin and the web app share one account and one balance, at the same price.

Claude Code

get started — install the vsb cli

curl -fsSL visualsandbox.com/install.sh | sh && vsb setup

Or paste the prompt into Claude Code — it installs the CLI, signs you in, and runs your first render.

Bring Claude, Cursor or Codex. Copy a setup prompt and it connects itself.

Paste this into Claude Code

Set up Visual Sandbox (visualsandbox.com) in Claude Code so you can generate images, video and audio for me.

1. Add the marketplace: claude plugin marketplace add visualsandbox/skills
2. Install the plugin: claude plugin install visual-sandbox@visual-sandbox
3. Run /mcp, pick visual-sandbox, and open the sign-in. Ask me before you approve anything on my behalf.
4. Run /mcp again and confirm visual-sandbox is connected. If it is not, stop and tell me what failed.
5. Do not generate anything yet. Every run costs credit, so ask me what to make, price it with estimate_cost, and wait for my yes.
