ABAPilot

An MIT-licensed MCP connector for ECC and on-premise S/4HANA that reads ABAP source and dictionary context, whose SAP-side half is a licensed product you install in the system.

Reads ABAP source and dictionary context so an assistant can explain an existing program and support a change against what the system actually contains. The connector is free and open; what it talks to is not, and the README says so on the second line. The publisher also documents its own limits unusually plainly: operational checks across four installations in September 2026 covering dictionary reads, component reads, dispatcher-source reads and syntax checks — and stating that writes, activation, transports, authorisation boundaries and production readiness were not tested. A separate MIT ABAP REST framework is published for inspection, with the caveat that it is not proof the checked installations run that commit.

Where it sits

Lives in
Provides
Agent access to your codeABAPAgent access to your codecapabilityLetting a coding agent read the project or the system you actually have, reach its model, its objects and its checks, and act on it. In file-based environments that works out of the box; complex systems need dedicated access capabilities. Whatever the environment, the agent also needs project- and framework-specific context, so it understands the thing in front of it rather than guessing from what it remembers of its training data. The transport is incidental: an MCP server, a language server or a CLI answer the same question, and what differs between them is how much of the real thing the agent can see. Distinct from [MCP servers](capability:mcp-servers), which is a protocol adapter on your own running service, and from [agent guidance](capability:agent-guidance), which is knowledge handed over as files rather than read from the thing itself.

Before choosing this

Signals

CommercialCommercialIts maker offers it commercially

Its maker states it is offered commercially: “Connecting to SAP requires a licensed ABAPilot backend installed in your system.” (NicoHern/abapilot-mcp — README, checked 2026-10-22).

Conditions

PracticalFunctional boundary

The MIT licence covers the connector only: connecting to SAP needs a licensed ABAPilot backend installed in your system, so this is a commercial decision wearing an open-source badge on one half. Its own published checks did not cover writes, activation, transports or authorisation boundaries.

PolicySAP API Policy 4.2026a§ 1.1, 1.2, 2.2.2from Agent access to your codeAn MCP server calls ADT or another SAP API of a running system for an agent.
  • § 1.1 Published APIs. Published APIs are made available for the documented purposes identified by SAP, including integration, extensions and data exchange.
  • § 1.2 Non-Published APIs. Customer and third-party applications must not access non-published APIs except where documentation permits it or SAP otherwise authorizes it.
  • § 2.2.2 AI call sequences and data extraction. Outside SAP-endorsed architectures, data services or expressly identified pathways, the policy prohibits specified agentic API use and systematic or large-scale extraction.

An agent that plans and executes ADT calls is the case section 2.2.2 names. Check that the endpoints are published for the intended use, and that the design runs within a pathway SAP identifies for it.

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

Listed on mcpservers.org

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.

Technical reference: Architecture

Tools

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

  • 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

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.

The final recorded ABAP Unit run passed 14 test methods. The scenario document records 15 passes out of 16 scenarios: 14 unit scenarios and a documentation review, with manual report integration not run. Material selection, SALV rendering, MM03 navigation and runtime termination before data selection were not verified by the unit run. The original report and material-master data were not changed. This is one configured sandbox installation, not evidence of production readiness or a promise of identical support on every SAP release.

The technical case contains screenshots and the coverage boundaries. The earlier four-minute creation demo is also available.

The recorded demo shows one sandbox workflow. In a live demo we can discuss your system, IDE and requirements before agreeing a customer trial. Choose a time.
