dassian-adt

MCP server for SAP ABAP development via the ADT API. Connect AI assistants to your SAP system — read, write, test, and deploy ABAP code without SAP GUI.

The AI can create objects, write source, activate, manage transports, run code, query tables, and check quality. Full development lifecycle, not just read-only or code generation.

Based on mcp-abap-abap-adt-api by [Mario Andreschak](https://github.com/mario-andreschak) and the abap-adt-api library by [Marcello Urbani](https://github.com/marcellourbani).

Dassian's fork adds input validation, error intelligence, MCP elicitation, session recovery, and a test suite. See CHANGES.md for the full list.

Automatic type mapping (CLAS -> CLAS/OC). | | Transports | transport_create, transport_assign, transport_release, transport_list, transport_info, transport_contents | Create, populate, and release transports. Smart metadata handling for FUGR/VIEW/TABL. | | Quality | abap_syntax_check, abap_atc_run | Syntax check and ATC with variant support. Workaround for CI-mode systems. | | Data | abap_table, abap_query | Read tables/CDS views with WHERE/LIKE/BETWEEN. Execute freestyle SQL. | | Run | abap_run | Create temp class, run ABAP code, capture output, clean up. Auto-detects ~run vs ~main across SAP releases. | | System | login, healthcheck, `aba
