If you are searching for SAP MCP Servers (Model Context Protocol), you quickly run into the same problem: Which SAP MCP servers exist (official and community), and what other SAP AI tooling should you know about? That is why I like this new repo: marianfoo/sap-ai-mcp-servers: SAP MCP Servers and SAP AI Skills list It is a curated list of SAP MCP servers, SAP AI skills, and adjacent developer tools. The README is structured as tables so you can scan by category, compare licenses, and see what is actively maintained. ...

Previous post (code generation benchmark): Benchmarking LLMs for ABAP Live benchmark results (old + new): abap-llm-benchmark.marianzeis.de In my first evaluation (based on the TH Köln benchmark paper), I extended the original setup with additional models and focused on a very concrete question: how well can LLMs generate ABAP code that actually compiles and passes ABAP Unit tests? I also tested SAP’s model ABAP-1, and it performed very poorly for code generation. To be fair: SAP also states this in the documentation. ABAP-1 is primarily meant for explaining ABAP code not for reliably generating full working implementations. ...

There is currently a huge hype around the new MCP (Model Context Protocol) servers. I’ve built one for SAP Docs, and there are excellent community projects like the ADT API MCP Server. These tools are fantastic for individual developers. You install them, connect them to your IDE or a local LLM, and suddenly your AI assistant knows about SAP. Architecture overview (in one picture) Before diving into the details, here is the high-level architecture I’m aiming for: ...

Live benchmark results: abap-llm-benchmark.marianzeis.de In a lot of SAP webcasts and webinars, especially around AI, the question comes up very early: which model are you using, and which one do you recommend? For CAP and UI5 the answer is usually pretty simple: use the current best model from Anthropic. If you add good context via MCP servers from the community or SAP, you are basically fine. There is just a lot of public knowledge available, and most of it is in JavaScript/TypeScript, which LLMs handle extremely well. ...

AI assistants already help a lot, but they work best when you can give them good context. In web apps, the most important context is usually the real traffic between frontend and backend: request URLs, payloads, and responses. When debugging, I want to copy that information quickly and completely. And since I mostly work with UI5 and OData, I usually need the full URL plus request and response body. In Chrome DevTools that often means a lot of manuall copy pasting, and if you need more than one request, it gets annoying fast. ...

Finally, there is an MCP server for ABAP. You can use it directly in Eclipse via https://mcp-abap.marianzeis.de/mcp. Setup instructions are here: Eclipse configuration (GitHub Copilot) Why a community ABAP MCP server? SAP has announced an MCP server for ABAP, so why create a community one? The trigger for me was the release of Agent Mode in GitHub Copilot for ADT, which finally makes it possible to edit ABAP code by Copilot. LLM models are already really good, but ABAP knowledge is still a recurring problem. So I wanted an MCP server that is actually tailored for ABAP. ...

I found Vivian Rose’s little web game “List Animals Until Failure” through a Hacker News thread (HN discussion) and immediately got hooked. Then I typed my first few animals… and realized my English animal vocabulary is not exactly perfect. So I did the only sensible thing and made a German version. The UI text is mostly translated with AI help (as all the other code). The part that actually took time was getting the animal names. ...

I wanted to have a local archive of my SAP Community blog posts for my own reference and to have a better overview of my content. Also I tried writing posts locally in Markdown first and then converting them to HTML. Mixed experience so far. Currently this is in a private repository and it fetches the latest posts from SAP Community daily if there are any new ones. I at least wanted to share my script so others can use it too. ...

I was recently asked how my UI5 Versions Bot on Bluesky works. So I want to simply explain how it works and how I use an RSS feed as a small “microservice” so I can base other services on this data. How the ui5-lib-diff project works The ui5-lib-diff project pulls data from official UI5 sources (SAPUI5/OpenUI5) and turns it into structured change data. That data is then used to generate an RSS feed entry for each patch update in both SAPUI5 and OpenUI5. ...
