erpl-adt

CLI and MCP server for the SAP ADT REST API — a single binary that talks the same HTTP endpoints Eclipse ADT uses. No Eclipse, no SAP NW RFC SDK, no JVM.

Part of the Datazoo ERPL family.

What it does

• Search and browse ABAP objects, packages, data dictionary tables, CDS views
• Read and write source code with lock management and transport integration
• Run tests — ABAP Unit and ATC quality checks from the command line
• Manage transports — create, list, and release transport requests
• MCP server — expose all capabilities to AI agents over JSON-RPC (MCP 2024-11-05)

Every command accepts --json for machine-readable output.

MCP server

erpl-adt includes a built-in MCP server (Model Context Protocol, version 2024-11-05) that exposes all ADT operations as tools over JSON-RPC 2.0 on stdin/stdout. This lets AI agents search, read, write, test, and manage ABAP code directly.

erpl-adt mcp --host sap.example.com --port 44300 --https

Configure it in your MCP client (e.g., Claude Desktop, Claude Code):

{
  "mcpServers": {
    "erpl-adt": {
      "command": "erpl-adt",
      "args": ["mcp", "--host", "sap.example.com", "--port", "44300", "--https"],
      "env": {
        "SAP_PASSWORD": "your_password"
      }
    }
  }
}

Deploy workflow

erpl-adt also includes the original deploy workflow for automated abapGit package deployment via YAML configuration:

cat > config.yaml <<EOF
connection:
  host: localhost
  port: 50000
  use_https: false
  client: "001"
  user: DEVELOPER
  password_env: SAP_PASSWORD

repos:
  - name: flight
    url: https://github.com/SAP-samples/abap-platform-refscen-flight.git
    branch: refs/heads/main
    package: /DMO/FLIGHT
    activate: true
EOF

export SAP_PASSWORD=your_password
erpl-adt deploy -c config.yaml

The deploy workflow is an idempotent state machine: discover → create package → clone → pull → activate. Each step checks preconditions and skips if already satisfied. Re-running is safe. Supports multi-repo deployments with depends_on for topological ordering.

Building from source

git clone --recurse-submodules https://github.com/datazooDE/erpl-adt.git
cd erpl-adt
make release

Requires CMake 3.21+, Ninja, and a C++17 compiler (GCC 13+, Apple Clang 15+, or MSVC 17+). vcpkg is included as a git submodule.

To run the tests:

make test                          # Unit tests (offline, no SAP system needed)
make test-integration-py           # Integration tests (requires SAP system)

Docker

docker build -t erpl-adt .
docker run --rm -v $(pwd)/config.yaml:/config.yaml \
    -e SAP_PASSWORD=your_password \
    erpl-adt deploy -c /config.yaml

Or use Docker Compose for end-to-end provisioning with a SAP ABAP Cloud Developer Trial:

docker compose up
