# Atelier201 documentation

Atelier201 hosts websites built with Astro for small businesses. The owner changes a
site by chat, in a content editor, or through their own AI agent, and nothing
reaches visitors until it is published.

[**Build your first site**](/docs/platform/quickstart)

Create a site, change it, preview it and publish it.

[**Integrate the REST API**](/docs/api/overview)

Everything the app can do, over HTTP, with one credential.

[**Work from the CLI**](/docs/cli/overview)

Push a project folder, build it and publish it, with JSON output for scripts.

[**Connect an AI agent**](/docs/mcp/overview)

Give an MCP client scoped access to build and edit sites.

> **Info: Four interfaces, one contract**
>
> The web app, the [REST API](/docs/api/overview), the [CLI](/docs/cli/overview)
> and the [MCP server](/docs/mcp/overview) call the same functions, so they apply
> the same checks. They differ in who is driving, not in what is allowed.
