ABAPilot — MCP connector for ABAP development on SAP ECC and S/4HANA

ABAPilot by Crimson Consulting connects AI coding assistants to SAP ECC and on-premise S/4HANA. Use SAP source code and dictionary context to understand existing ABAP, review proposed changes and support development from your preferred MCP-capable coding client.

The connector is free and MIT-licensed. Connecting to SAP requires a licensed ABAPilot backend installed in your system.

Evidence you can inspect

• Four-installation operational checks, 9 September 2026: two ECC and two S/4HANA installations passed dictionary reads, component reads, dispatcher-source reads and positive/negative syntax checks. This did not test writes, activation, transports, authorization boundaries or production readiness.
• Public MIT-licensed ABAP REST framework: inspect the table-driven endpoint registry, dispatcher and example handlers. This framework is separate from the licensed ABAPilot backend and is not proof that the checked installations run an identical public commit.
• Published MCP catalog: the npm 1.0.6 connector exposes 49 tools. Catalog discovery is not evidence that every operation works on a particular SAP installation.

Start with an existing ABAP program

Ask your assistant to explain a program using source and dictionary definitions retrieved from SAP. Review the references it used before moving to a proposed change. Available operations depend on the connector version, installed backend and enabled endpoints.

Architecture and prerequisites

The MCP connector runs outside SAP and calls the licensed SAP-side backend. Agree the SAP release, backend version, HTTPS endpoint, individual user permissions and permitted operations with your SAP team before a customer trial.

Start the connector using npx -y abapilot. This command does not install the SAP backend. Follow the linked setup guide for client-specific configuration and secret handling. Pin a reviewed connector version for repeatable team rollouts.

Tools

The current repository catalog lists 49 tools. Availability depends on the installed connector, backend version and enabled endpoints.

Data Dictionary & metadata

• sap_read_table_structure — Retrieves the metadata of a Data Dictionary table including field definitions, data types, keys, and descriptions
• sap_read_object_details — Read comprehensive details about any SAP repository or DDIC object
• sap_read_object_info — Get metadata about an ABAP object including creation date, last changed date, author, and package
• sap_check_type_exists — Checks whether a type exists in the SAP Data Dictionary and returns its kind
• sap_read_domain_values — Retrieves the fixed values defined for a domain
• sap_read_field_domain_values — Get domain fixed values for a specific table field
• sap_read_foreign_keys — Read foreign key relationships for a table from Data Dictionary (DD08L)
• sap_infer_joins — Automatically detect join keys between two tables based on domain matching
• sap_get_field_metadata — Get enriched metadata for SAP table fields with semantic classification
• sap_list_package_objects — List all ABAP repository objects in a development package (DEVCLASS)

ABAP code

• sap_read_code — Retrieves the source code of an ABAP object (program, class, or function group)
• sap_read_includes — Retrieves all include files for a program with their source code
• sap_read_dynpros — Retrieves screen definitions for a program including field lists
• sap_read_texts — Retrieves text elements (selection texts, text symbols) for a program
• sap_read_where_used — Queries SAP's cross-reference tables (WBCROSSGT/WBCROSSI) to find what objects use a given object (forward) or what a given object uses (inverse)
• sap_get_enhancements — List ALL enhancements for a SAP transaction or program in one call
• sap_syntax_check — Validates ABAP source code for syntax errors without creating or activating it
• sap_write_code — Forward a source-write request; object support, validation and activation depend on the installed backend
• sap_write_code_safe — Forward a request to the backend; safeguards are not implemented by the public Node connector and its input schema is incomplete
• sap_patch_code — Forward a source-patching request; supported patch arguments and validation depend on the backend

Operations & troubleshooting

• sap_read_dumps — Query ABAP runtime errors (short dumps) from SAP's ST22 transaction
• sap_read_dump_details — Get detailed information for a specific short dump including full error texts, cause, and solution
• sap_read_syslog — Query system log entries from SAP's SM21 transaction
• sap_read_jobs — Query background job information from SAP's SM37 transaction
• sap_run_program — Request report execution; output depends on the backend, with no timeout or background-job fallback implemented by this connector
• sap_run_transaction — Run the ABAP report behind a report transaction code, optionally with a selection-screen variant, and return its list output
• sap_save_variant — Create or overwrite an ABAP selection-screen VARIANT for a report, so it can be reused by sap_run_program (and the performance trace / headless…
• sap_read_user_locks — Query user lock status from USR02 table
• sap_diagnose_message — Diagnose a SAP error/warning/info message end-to-end
• sap_lookup_t100 — Look up a specific SAP T100 message by message class and number

• sap_scan_security_notes — Discover ABAP Security/HotNews notes for a SAP patch-day month and rank them by relevancy to this system
• sap_check_notes_relevancy — Check relevancy of one or more SAP Note numbers against this system (component/SP levels, download state, implementation readiness)

Translation

• sap_read_translations — Reads translatable texts from a SAP object in source and optionally target language
• sap_write_translations — Writes translated texts back to a SAP object
• sap_translate — Composite tool: reads translatable texts from a SAP object, translates them using AI, and optionally writes them back

Knowledge

• sap_search_knowledge — Search SAP documentation and community for information on any SAP topic

The catalog is gated in two places. In your system, the /ABAPILOT/CONFIG (or /TSRA/CONFIG) endpoint registry decides which endpoints are live — switch one off and the tool stops working, with no client change. On the client side, ABAPILOT_TOOLS narrows what a given MCP client sees:

"env": { "ABAPILOT_TOOLS": "sap_read_table_data,sap_read_code,sap_syntax_check" }

The licensed backend may expose operations beyond this public catalog. Agree the required capabilities and verify them on the deployed version before a trial.

Validation and data handling

The public connector advertises source and dictionary readers, syntax checking and write endpoints. Validation and deployment safeguards depend on the installed backend. A syntax check must not be assumed for every write. Confirm the enabled endpoints, validation behavior, authorization failures and log attribution on your deployed version.

Review which SAP context your chosen AI client and model provider receive. Using your own API key does not by itself establish local processing or a particular retention policy.

Evaluate the workflow

The September 2026 walkthrough uses Claude Code, ABAPilot and a lifecycle skill to change a sandbox copy of an existing material-description report, then update its technical specification and test scenarios. Length and invalid-character checks run independently; a regex-cache regression checks that changing patterns does not reuse a stale expression.
