ARC-1 on SAP BTP: Secure ABAP Agentic Development Beyond the Laptop

Series note: This post is part of my AI ABAP development series, where I go from AI development in general, to ABAP-specific problems, and then to ARC-1. In the previous post, I introduced ARC-1 as a secure ADT MCP gateway for ABAP systems. The main point was not only that ARC-1 can expose ABAP development functionality to AI clients. The main point was that this access needs a place in the architecture. This post is about that place. If ARC-1 should not run uncontrolled on every developer laptop, then SAP BTP is the most natural enterprise option for me. Not because BTP makes the problem disappear, but because it already has the pieces you need for this kind of setup: XSUAA, destinations, Cloud Connector, role collections, audit logging, and the normal BTP operating model. ...

Introducing ARC-1: A Secure ADT MCP Server for Enterprise SAP Development

Series note: This post is part of my AI ABAP development series, where I go from AI development in general, to ABAP-specific problems, and then to ARC-1. In the first post of this series, I wrote about context and how I use AI in development. In the previous post, I then moved that discussion into ABAP and ended more or less with one question: what would an ADT MCP setup need to look like if you take control, identity, and security seriously from the beginning? ...

ABAP and Agentic AI: The Hidden Problem in Real Projects

Series note: This post is part of my AI ABAP development series, where I go from AI development in general, to ABAP-specific problems, and then to ARC-1. In the first post of this series, I wrote more generally about how I use AI today, why context matters so much, and why I am still not fully convinced by the more maximalist agentic hype. Here I want to get more concrete. Because SAP development is not one thing, and that matters a lot for AI. ...

How I Use AI for Development and Why Context Matters

Series note: This post is part of my AI ABAP development series, where I go from AI development in general, to ABAP-specific problems, and then to ARC-1. When it comes to AI, I do not really think about magic. I think more about another colleague helping me out. Sometimes that means architecture. Sometimes implementation. Sometimes testing, review, CI/CD, or deployment. But this only works with trust, and trust needs communication. If I do not know something, I ask. If code looks strange, I ask. If tests fail, I ask. ...
