## What it does

The server connects to SAP ECC/S/4HANA (on-premise) and SAP BTP ABAP Cloud and exposes read-only tools: where-used, object metadata, repository navigation, structure and dependency analysis. Nothing gets written back — that is the point, since analysis should rest on what the system actually contains rather than on what the model assumes.

It runs through `npx -y @mcp-abap-adt/core-ro`. Auth is destination-based: a service key file sits in the `service-keys` directory, and you pass its filename without the extension as `--mcp=<destination>`. Three options exist — basic over HTTP or RFC, SNC over RFC without a password, and JWT with a browser login. A JWT you already have goes in the `x-sap-jwt-token` header of `mcp-abap-adt-http` / `mcp-abap-adt-sse`. Transports are stdio, HTTP and SSE.

HTTP asks for nothing beyond Node.js 22 or 24. Pick RFC or SNC and you also need the SAP NW RFC library: the 64-bit `sapnwrfc.dll` from SAP GUI on Windows, otherwise the SAP NW RFC SDK. Without it the server will not start in that mode. Legacy BASIS < 7.50 systems are out of scope.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `MCP_ENV_PATH`, `AUTH_BROKER_PATH`, `MCP_BROWSER`, `MCP_BROWSER_AUTH_PORT`, `MCP_UNSAFE`, `SAP_CONNECTION_TYPE`, `SAP_SYSTEM_TYPE`, `SAP_LANGUAGE` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

### Claude Code (native platform)

**Platform CLI**

## When to use it
- trace every usage of an ABAP object before touching it
- inspect the structure of a class or function module
- map dependencies between objects across the repository
- pull object metadata straight from the system
- judge the impact of a change on related artifacts

## Example prompts
- Show me where class `ZCL_ORDER_HANDLER` is used
- Walk through the structure of function module `Z_GET_PRICE`
- Find every repository object that depends on this CDS view
