DAB Agent Skills (Data API Builder)
Copilot Chat skills pack for Data API Builder - guides Copilot to create REST, GraphQL, and MCP APIs from your database without writing code.
What is Data API Builder?
Data API Builder (DAB) is a free, open-source tool from Microsoft that instantly creates:
| Endpoint |
Description |
| REST API |
Full CRUD operations with OData-style filtering, pagination |
| GraphQL API |
Queries, mutations, and nested relationships |
| MCP API |
Model Context Protocol for AI tool integration (Claude, Copilot, etc.) |
All from a single JSON configuration file - no code required! DAB is a foundational component of Microsoft Fabric.
Supported Databases: SQL Server, Azure SQL, PostgreSQL, MySQL, Cosmos DB
How this extension works
This extension contributes a comprehensive set of Copilot Chat skills that activate automatically based on what you ask. There is no @dab chat participant - you just talk to Copilot normally and the relevant skill is invoked.
For example, asking "add a one-to-many relationship between Products and Categories" will load the data-api-builder-relationships skill; asking "deploy DAB to App Service" will load the azure-app-service-data-api-builder skill.
