# Cmssy

> cmssy is an AI-native headless CMS. You model structured content and edit it
> visually or through Claude (via the cmssy MCP server); your own frontend
> renders it with the @cmssy/next SDK. cmssy never hosts your site.

## Key facts

- Content is composed from typed blocks; block schemas live in your frontend code.
- Data collections are models with records, delivered over a typed GraphQL API.
- Claude connects through the cmssy MCP server and edits content directly - never your code.
- Built-in commerce: products, carts, orders, discounts, order pipelines.
- Every field is multilingual by default.
