Features
MCP Tools
| Tool | Description |
|---|---|
abap_analyze |
Deep code analysis: syntax, performance, security, Clean ABAP, cyclomatic complexity. Optionally integrates SAP Code Inspector via ADT. |
abap_generate |
Generate production-ready ABAP from natural language – classes, CDS views, RAP behaviors, OData services, unit tests, and more. |
abap_explain |
Plain-English explanation of any ABAP code. Adjustable audience level (beginner → expert). Optional line-by-line annotations. |
abap_refactor |
Refactor towards Clean ABAP: extract methods, modernize syntax, improve naming, add error handling, convert to OOP. |
abap_search |
Search ABAP repository objects in a connected SAP system (requires ADT credentials). |
abap_unit_test |
Generate ABAP Unit Test classes using ABAP Unit + Test Double Framework. Optionally run existing tests via ADT. |
abap_format |
Format code: 2-space indentation, uppercase keywords, replace deprecated syntax (MOVE→=, SELECT *→explicit fields). |
abap_docs |
Comprehensive documentation for ABAP keywords, statements, classes, and SAP concepts with version-specific notes. |
MCP Resources
| Resource URI | Content |
|---|---|
abap://syntax-reference |
ABAP data types, modern 7.4+ syntax, constructor expressions, string templates |
abap://best-practices |
Clean ABAP naming, DB access patterns, exception design, unit testing |
VS Code Extension (`@abap` Copilot Agent)
Use @abap in Copilot Chat with these slash commands:
@abap /analyze ← analyze the current file
@abap /generate a CDS view for sales order header with customer join
@abap /explain ← explain selected code or whole file
@abap /refactor ← clean up current file
@abap /test ← generate unit tests for current class
@abap /doc
