MCP server for SAP ECC and S/4HANA
Give any AI assistant governed access to SAP.
The Skybuffer AI MCP server is an ABAP add-on that publishes SAP business data, transactions and development tools as MCP tools. Every call runs as the signed-in user, with SAP authorizations enforced in the ABAP kernel.

What is Model Context Protocol, and why does it matter for SAP?
Model Context Protocol (MCP) is the open standard that AI assistants and agents use to discover and call tools. Claude, ChatGPT, Gemini, Microsoft Copilot and VS Code all speak it.
Without an MCP server in SAP, every assistant needs its own integration, its own credentials and its own idea of who may see what. With one inside the ABAP stack, a single governed tool layer serves every assistant, and SAP stays the authority on access.
Three families of SAP tools.
Start with the tools you need and add more as ABAP classes. Each tool describes itself, so any MCP client knows when and how to call it.
Transactional tools
Create, update and delete in SAP, with change documents and a full audit trail.

Development tools
Give developers and coding assistants the context they need, straight from the system.

How a tool goes from idea to production.
The same lifecycle as any other ABAP development, so your SAP team already knows how to run it.
Read how to create MCP tools- 1
Build
Write the tool as an ABAP class, with its description and parameters.
- 2
Register
Add it to the MCP tool registry so every client can discover and call it.
- 3
Transport
Move it through development, quality and production with your normal transports.
- 4
Call
Any MCP client calls it; it runs as the signed-in user, with authorization checks.
- 5
Audit
Every change is recorded in SAP, next to the user who made it.
One tool layer for every client.
Business users, developers and agents reach the same governed tools, from wherever they already work.

Platform MCP servers
More MCP servers for the people who build on SAP.
Alongside the ABAP MCP server run platform MCP servers on SAP HANA on-premise or SAP BTP. Deploy them separately or combined.
Code Intelligence
Vectorized documentation of your custom ABAP, so assistants can answer what a Z object does and what depends on it.
Development rules
Your in-house development rules, applied every time an assistant writes or reviews code.
Utility tools
ABAP Cleaner and other development utilities, available to any MCP client from the editor your developers already use.
Common questions about the MCP server for SAP
Can ChatGPT, Claude or Gemini connect to SAP?
Yes. Through the Skybuffer AI MCP server they call SAP tools directly, as the signed-in user, with SAP authorizations checked on every call.
Does the MCP server work with SAP ECC, or only S/4HANA?
Both. It runs inside the ABAP stack of SAP ECC and SAP S/4HANA, on-premise or connected from your SAP BTP subaccount.
How are SAP authorizations enforced for AI agents?
The tools run in ABAP as the calling user, so the standard PFCG authorization checks apply. An assistant can never see or change more than the person using it.
Do we need SAP BTP or SAP Integration Suite?
No. The MCP server runs in the ABAP system. If you use SAP Integration Suite, its MCP gateway can sit in front of it.
Can we build our own MCP tools?
Yes. Tools are ABAP classes, so your developers build, register and transport them like any other ABAP object.
