Data API builder: REST, GraphQL and MCP for your databases

Data API builder generates REST and GraphQL endpoints, as well as MCP tools, from Azure databases and on-premises stores. It supports several backends, including Azure SQL, SQL Server, PostgreSQL, MySQL and Cosmos DB, and runs in a container or locally during development.

Configuration defines entities and their permissions; DAB then translates requests into SQL. This layer reduces the API code teams need to maintain, while access remains shaped by the configuration and each database’s capabilities.
