# Dropyour > Dropyour is where you push and operate a system of apps made by any AI. Start with one self-contained HTML app and get a stable public URL in seconds, no account, no build; or publish up to five apps at once. Without an account, an app stays online for 30 days; a free account keeps it a year, Pro keeps it for good. Connect your AI via MCP to publish straight from the chat, then keep operating from there: settings and data, plus versions and rollback for a server app. With an account, group up to nine apps into a system: link them under a checked contract, let one notify another, give them one shared visitor sign-in, save and roll back the versions of their server apps together, transfer the whole system to a client, export it. A server app also runs YOUR server code (`server.js`): a queryable store, a clock, secrets, signed-in visitors, files and realtime; ask the MCP prompt `dropyour_perfect_prompt` in `server` mode for the exact API. Content is hosted in the EU and scanned at publish time. One origin per drop: the URL never changes and visitors' browser data survives updates. Every doc page is also available as Markdown: append `.md` to its URL (e.g. https://dropyour.io/en/docs/concepts.md). ## Documentation - [Introduction](https://dropyour.io/en/docs): What Dropyour is, the ways to publish (web, MCP, prompt, import, a whole system), and where a server app fits. - [Concepts](https://dropyour.io/en/docs/concepts): Stable URL / origin contract, drop lifecycle, graduated expiration, management link, shared memory. - [Export from your AI](https://dropyour.io/en/export/): Step-by-step guides to get your HTML out of ChatGPT Canvas, Claude Artifacts or Gemini Canvas and publish it. - [Publish & manage](https://dropyour.io/en/docs/publish): Publish on the web and manage a drop: name and tags, expiration, scheduling, password, who can edit, replace, transfer, reactivate, delete. - [Accounts](https://dropyour.io/en/docs/accounts): Passwordless magic-link sign-in, cloud memory, AI read/write over MCP, attach a drop, GDPR deletion. - [Pro](https://dropyour.io/en/docs/pro): What Pro unlocks, tiers table, permanent, badge, billing. - [App systems](https://dropyour.io/en/docs/systems): Group up to nine apps into a system: link them under a checked contract, let one notify another, one shared visitor sign-in, save and roll back the versions of server apps together, manifest plan/apply, transfer to a client, export, delete. - [Connect your AI (MCP)](https://dropyour.io/en/docs/mcp): Connect your AI via MCP: endpoint, per-client setup, authentication, OAuth, 37 tools, error codes. - [Grow your app](https://dropyour.io/en/docs/grow): The graduation founding cohort: your drop becomes a real backend, same URL, same data; apply from your drops, graduate through your AI once subscribed; proof dossier, full export, redeployment to your own account. - [Operate your graduated app](https://dropyour.io/en/docs/operate): Running a level-4 app: publish and roll back versions, monthly usage cap, dated health, hourly backups, self-service export, billing and cancellation, stepping down and back up, what MCP does not expose. - [Security & privacy](https://dropyour.io/en/docs/security): Content scanning, abuse reporting, EU data hosting, shared-memory guarantees, retention. - [Sub-processors & commitments](https://dropyour.io/en/docs/subprocessors): Exhaustive sub-processor list (role, data, safeguards), technical third parties with no personal data, and operational commitments: availability, backups, incidents, reversibility. - [FAQ](https://dropyour.io/en/docs/faq): Frequently asked questions and glossary. ## MCP - MCP endpoint (Streamable HTTP): https://mcp.dropyour.io/mcp - [MCP reference](https://dropyour.io/en/docs/mcp): per-client setup, dyk_ account token, OAuth, 37 tools, error codes.
