ABAP MCP - Model Context Protocol - Server SDK
Discord - for all ABAP-AI repos.
ABAP implementation of the Model Context Protocol, supporting up to version 2025-11-25. \ Note that this is only a server implementation as I currently see no realistic way to support SSE streaming which is mandatory for the client.
Supported protocol versions: 2025-03-26, 2025-06-18, 2025-11-25
Important: This SDK version will only support up to 2025-11-25 and is frozen except for error corrections. 2026-07-28 and further are implemented in the new ABAP MCP SDK V2. The vast number of breaking changes and different approaches made it challenging to properly support all versions. As especially the complex session support is gone I decided to make a clear cut and create a V2 SDK. The new SDK will support on best effort basis old MCP versions down to 2025-03-26 as long as no sessions are required.

Currently implemented:
No SSE support --> no notifications and therefore no support of listChanged, subscribe and logging.\
Not implemented:
Implement the standard Authorization in ABAP via custom code is not feasible, we have to rely on ABAP features. \ An overview of likely options is outlined in Authentication Documentation.
OAuth is suggested but outside of newer S/4HANA releases challenging, for options see Authentication. Further suggestions are welcome.
See currently open issues for the next planned steps. Longer term I intend to add features to create modular MCP servers based on reusable implementations.

Part of the coding was generated using AI, mostly with Sonnet 3.7/4 and GitHub Copilot. Detailed documentation is largely AI generated - only high-level reviewed.
