Tiniest Cloud

Build a web app in a conversation with Claude, or with your coding agent, and put it online at Tiniest Cloud. Every app gets sign-in, per-user storage, realtime, push notifications, scheduled jobs and an AI model — with no keys to manage and no backend to write.

This plugin adds two things:

• The Tiniest Cloud MCP server (https://app.tiniest.cloud/mcp). Claude can deploy a folder and get a live URL, share an app by email, roll back to an earlier version, connect a third-party API without putting its key in the page, schedule recurring work, and put an app on your own domain, and read or change the data an app has saved.
• The tiny skill, which tells Claude how to build for the platform — a static frontend using the tiny SDK, no login flow, no localStorage, no server of its own (server logic goes in backend functions) — and to fetch the current SDK reference with the tiny_guide tool before it starts.

Starting from scratch in a terminal, one command makes a project already set up for Tiniest Cloud — React, TypeScript, Vite, Tailwind CSS and shadcn/ui for an app, or Astro for a website:

npm create tiniest-cloud@latest my-app
npm create tiniest-cloud@latest my-site -- --template site

Install

Claude (web, desktop, mobile and Cowork): open Customize → Plugins → Discover, find Tiniest Cloud and add it, then connect it on the plugin's Connectors tab.

Cursor: find Tiniest Cloud in the Marketplace and click Add.

Claude Code:

/plugin marketplace add mohamedyameen/tiniest-cloud-plugin
/plugin install tiniest-cloud@tiniest-cloud

Gemini CLI:

gemini extensions install https://github.com/mohamedyameen/tiniest-cloud-plugin

Then run /mcp auth tiniest-cloud inside Gemini CLI to sign in.

Any other MCP client: add the server https://app.tiniest.cloud/mcp (Streamable HTTP).

The first time Claude uses a Tiniest Cloud tool, your browser opens to sign in (or create a free account). There is no API key to paste.

Try it

• "Build a small expense tracker and put it on Tiniest Cloud."
• "What apps do I have on Tiniest Cloud?"
• "Share my notes app with sam@example.com."

What it sends

Everything goes to Tiniest Cloud at app.tiniest.cloud, and only when Claude calls one of its tools on your behalf:

• the files of an app you ask Claude to deploy;
• the email addresses of people you share an app with or add to a space;
• entries you ask Claude to write to an app's saved data, and the details of any API connection or scheduled job you set up.

Reading tools send only the name of the app and what to look up. The plugin itself stores nothing and runs no code on your machine; the skill is text, and the server is hosted.
