+# Data API builder Core Library for Azure Databases
+
+[![License: MIT](https://img.shields.io/badge/license-MIT-blue.svg)](https://opensource.org/licenses/MIT)
+
+## About
+
+**Microsoft.DataApiBuilder.Core** is the core engine library for [Data API builder](https://learn.microsoft.com/azure/data-api-builder/) (DAB). It provides the runtime components needed to generate and execute secure REST, GraphQL endpoints and MCP tools backed by Azure SQL and other databases.
+
+This package is intended for developers who want to embed or extend the Data API builder engine within their own .NET applications or services.
+
+## Supported Databases
+
+- Azure SQL / SQL Server
+- Azure SQL Data Warehouse
+- Azure Cosmos DB (NoSQL)
+- PostgreSQL
+- MySQL
+
+## Key Capabilities
+
+- **REST API engine** � Automatically generates CRUD endpoints (POST, GET, PUT, PATCH, DELETE) with filtering, sorting, and pagination
+- **GraphQL engine** � Generates queries and mutations with filtering, sorting, pagination, and relationship navigation
+- **MCP tool support** � Exposes DML and custom MCP tools for building SQL MCP Servers
+- **Authentication** � OAuth2/JWT and EasyAuth (Azure App Service / Static Web Apps)
+- **Authorization** � Role-based access control with item-level security via policy expressions
+- **Configuration-driven** � Define entities, permissions, and relationships in a JSON config file; no code required
+- **Multi-database** � Connect to multiple database types from a single instance
+- **Caching** � Built-in response caching with [FusionCache](https://github.com/ZiggyCreatures/FusionCache)
+
+## Installation
+
+```bash
+dotnet add package Microsoft.DataApiBuilder.Core
+```
+
+## Usage
+
+This library provides the core services and middleware used by the Data API builder runtime. Register the DAB services in your application's dependency injection container and configure them using a [DAB configuration file](https://learn.microsoft.com/azure/data-api-builder/reference-configuration).
+
+For a complete, ready-to-run experience, consider using the [`Microsoft.DataApiBuilder`](https://www.nuget.org/packages/Microsoft.DataApiBuilder) NuGet package or the [DAB CLI](https://learn.microsoft.com/azure/data-api-builder/how-to-install-cli).
