Overview

What is ABAP Model Context Protocol Server SDK?

An ABAP implementation of the Model Context Protocol (MCP), supporting protocol versions up to 2025-11-25. It is a server-only SDK — SSE streaming, which is mandatory for the client, is not supported. This SDK is intended for ABAP developers building MCP servers with capabilities like prompts, resources, tools, and tasks.

How to use ABAP Model Context Protocol Server SDK?

Refer to the Overview in the docs folder for installation and configuration details. The SDK integrates ABAP open-source projects including ajson, abaplint, and abapGit.

FAQ from ABAP Model Context Protocol Server SDK

What protocol versions are supported?

Supported versions: 2025-03-26, 2025-06-18, and 2025-11-25. Older versions may be dropped over time.

Does the SDK support SSE for client connections?

No. SSE streaming is required for the client side, and the maintainer sees no realistic way to implement it in ABAP. Only the server side is provided.

What ABAP open-source projects does it depend on?

It integrates ajson, abaplint, and abapGit. More related projects are listed at dotabap.org.

How is authorization handled?

Standard MCP authorization via custom code is not feasible in ABAP. The server relies on ABAP-native features; an overview of options is in the Authentication documentation.
