We're the last dev ecosystem without real AI tooling. Copilots autocomplete ABAP, but they can't actually see your system or change anything in it.

So I built a small bridge over the standard ADT API (the same one Eclipse/ADT uses). With it, an AI assistant (Claude, Cursor, etc.) can work directly in your system:

• read & search classes/programs/includes/function modules, run a syntax check, execute an IF_OO_ADT_CLASSRUN class (the Eclipse "F9")
• and, when you turn it on: patch a single spot in a 40KB include without retyping it, create objects, activate, inject implicit enhancements (no modification of the standard), maintain customizing tables (SM30-style, transport-aware), create dynpros headlessly, and drive the SAP Note Assistant.

One bit fellow ABAPers might appreciate: it handles the ADT 405 ExceptionResourceIsModified lock on Z-copies of standard objects (RSTAT='P' / SMODISRC) by falling back to RPY_PROGRAM_UPDATE, so the write still goes through.

Safe by default: read-only out of the box; writes require an explicit flag, a per-call confirm, and a transport, with a syntax check before each save. Pure Python (no dependencies). Free / MIT.

SAP/ABAP is one of the last big dev ecosystems without proper AI tooling. Copilots can generate ABAP text, but they can't see your repository or touch your code.

So I built abap-mcp — an MCP server that talks to SAP's standard ADT REST API (the one Eclipse uses). With it, Claude/Cursor can:

• read & search the ABAP repo, run syntax checks, execute classrun (the Eclipse "F9")
• and, opt-in: patch source surgically, create objects, activate, inject implicit enhancements, maintain customizing tables, create dynpros headlessly, and drive the SAP Note Assistant.

A couple of implementation notes that might interest this sub:

• No SDK — pure Python stdlib. The official mcp package + httpx blew past the connection timeout behind our corporate antivirus (~30s startup); hand-rolled JSON-RPC over stdio + urllib gets the handshake to ~5s.
• Nastiest thing it solves: the ADT 405 ExceptionResourceIsModified lock on Z-copies of standard objects — it auto-falls-back to RPY_PROGRAM_UPDATE so the write still lands.

Read-only by default; writes need an explicit flag + confirm + transport. Free/MIT.

Repo in the comments. Feedback very welcome — and if you work with SAP, what would you want an AI to do in your system?
