MCP + RESTYour tools. Your workflow.

A few small details.

All your questions

Can I try it without an account?

Yes. Quick shares are free and anonymous. Open the playground or ask your connected agent to publish HTML, Markdown, Mermaid, JSON or CSV. You'll need an account for lasting projects.

What can my agent publish?

A page, a prototype, a report, a diagram or a dataset. For an app that needs to save data or support returning visitors, create a project with its own database, realtime updates and Google sign-in.

How long does it stay online?

Quick shares expire after 7 days and support up to 1 MB. Projects stay live, or you can give them an expiry schedule. Password protection and one-time links are available for quick shares.

What if I don't use MCP?

Your agent can publish through the REST API instead. You can also use the browser playground without connecting an agent. The docs cover both approaches.
