-> dbt Server supported our legacy Semantic Layer, which was [fully deprecated in December 2023.](https://docs.getdbt.com/docs/dbt-versions/release-notes/Dec-2023/legacy-sl). In October 2023, we introduced the GA of the revamped dbt Semantic Layer with [significant improvements](https://www.getdbt.com/blog/build-centralize-and-deliver-consistent-metrics-with-the-dbt-semantic-layer), made possible by the [acquisition of Transform](https://www.getdbt.com/blog/dbt-acquisition-transform) and the integration of [MetricFlow](https://docs.getdbt.com/docs/build/about-metricflow) into dbt. The dbt Semantic Layer is now independent of dbt Server and operates on MetricFlow Server, a new proprietary technology designed for enhanced connectivity and scale.

 Welcome to the `dbt-server` repository! The dbt Server is intended to provide a web API for [dbt](https://github.com/dbt-labs/dbt-core) operations and replace the [`dbt-rpc`](https://github.com/dbt-labs/dbt-rpc) Server.
