abap-mcp — Read & write ABAP from Claude, Cursor & any MCP client

An MCP (Model Context Protocol) server that connects AI assistants (Claude Desktop, Claude Code, Cursor, …) directly to a SAP system over the standard ADT (ABAP Development Tools) HTTP API. Your AI can read, search, syntax-check — and, when you enable it, write, activate, and refactor real ABAP — without leaving the chat.

No SDK bloat. Pure Python standard library — starts in seconds even behind aggressive corporate antivirus, and runs on any Python 3.x.

Why this exists

ABAP developers are the last ones to get good AI tooling. Copilots can write ABAP text, but they can't see your system or touch your code. This bridges that gap using the same ADT REST API Eclipse uses — so it works against any modern SAP NetWeaver / S/4HANA system you can already reach.

It's the missing link between an LLM and a live SAP repository.

Safe by default

Out of the box the server is read-only. Write tools stay dormant until you explicitly opt in with SAP_ALLOW_WRITE=1 in your .env — and even then, every write additionally requires an explicit confirm flag and a transport request, with a syntax check before each save. So you can hand it to your AI and let it explore your system with zero risk, then flip the switch when you're ready to let it build.

What it can do

Read (always on):

• abap_ping — connectivity / auth check

• abap_search — find objects across the repository

• abap_read_class / abap_read_program / abap_read_include / abap_read_function / abap_read_uri

• abap_sql — read-only SELECT against tables

• abap_syntax_check — validate source without saving

• smartform_info / sapscript_info — inspect forms

Write & generate (enable with SAP_ALLOW_WRITE=1):

Note Assistant apply is dry-run by default and refuses to run against a production system id.

Setup (60 seconds)

git clone <repo>
cd abap-mcp
cp .env.example .env      # fill in host, client, user, password

.env:

SAP_BASE_URL=http://your-sap-host.example.com:8000
SAP_CLIENT=100
SAP_USER=YOUR_SAP_USER
SAP_PASSWD=YOUR_PASSWORD
SAP_LANG=EN
SAP_ALLOW_WRITE=0          # set to 1 to enable the write/generate tools

Register with Claude Code / Desktop:

claude mcp add abap-mcp --scope user -- python /path/to/server.py

Or in any MCP client, point it at python server.py over stdio.

Ask your assistant: "ping the SAP system and list all Z-classes whose name starts with ZCL_."

Requirements

• Python 3.8+ (no pip dependencies)

• Network access to a SAP system's ADT endpoint (/sap/bc/adt/*)

• A SAP user with developer authorizations (and a transport for writes)
