ABAP Development via SAP ADT

You have access to SAP ADT MCP tools (server user-sap-adt in Cursor, key sap-adt in .cursor/mcp.json) that let you interact with the SAP ABAP system directly from Cursor.

Connection

• Systems are not hardcoded here: call sap_list_environments to see what is configured on this machine, then connect to one of them.
• Always call sap_connect before any SAP operation if not already connected.
• Preferred: use sap_connect(system_id="<ID>") to load saved credentials from the OS credential manager.
• If no saved credentials exist, tell the user to run sap-adt add <SYSTEM_ID> in the terminal — it prompts for the password without echoing it, keeping it out of the chat history. Only fall back to sap_save_password if they prefer to type it here.
• Fallback: password can also come from SAP_PASSWORD environment variable.
• On an unfamiliar or older system, run sap_system_info once after connecting: it lists which ADT endpoints exist there, so you know upfront whether activation, transports and syntax check work.
• sap_disconnect ends the session when switching to another system.

Reading ABAP Code

• Use sap_search with wildcards (e.g., Z*, ZCL_*) to find objects.
• Use sap_read_source with the correct object_type:
  • PROG for programs/reports
  • PROG/I for includes
  • CLAS for classes
  • INTF for interfaces
  • FUGR for function groups
  • TABL, DTEL, DOMA, VIEW for DDIC objects
• Other types (function modules, message classes, …) are resolved automatically via repository search; if that fails, pass source_uri directly (e.g. from sap_object_metadata).

Modifying ABAP Code

• Always use sap_write_source — it handles locking, transport assignment, writing, activation, and unlocking in one call.
• If the object is in a non-$TMP package, you must provide a transport_request.
• If no transport is available, create one with sap_create_transport first.
• Check lock status with sap_check_lock before attempting modifications.
• If an object is locked by another user, do NOT attempt to modify it.
