An Eclipse ADT plugin that exposes your SAP ABAP systems to AI coding assistants via the Model Context Protocol (MCP). It runs an embedded HTTP server inside Eclipse, so any MCP-compatible client — Claude Code, Cursor, Windsurf, and others — can search, read, edit, test, and analyze ABAP code through your existing ADT SNC/SSO session.

Connect multiple ABAP projects simultaneously and route each tool call to the right system via a systemId parameter.

No credentials are stored or transmitted by the plugin. Authentication is handled transparently by the Eclipse ADT communication framework.

Installation

Via Eclipse Update Site

In Eclipse ADT, go to Help > Install New Software...
Click Add... and enter:
- Name: EPOD ADT MCP Server
- Location: https://git.epod.dev/erhan/epod-adt-mcp-updatesite/raw/branch/main/
Select EPOD ADT MCP Server from the list
Click Next, accept the license, and complete the wizard
Restart Eclipse when prompted

Via dropins (quick install)

Download the plugin JAR from the latest release and drop it into your Eclipse dropins/ folder, then restart Eclipse.

Requirements

Eclipse 2024-03 or later with SAP ADT (ABAP Development Tools) installed
Java 17 or later
One or more ABAP projects in your Eclipse workspace with active SNC/SSO connections to SAP

Setup

1. Open the MCP Server view

Window > Show View > Other... > ABAP MCP Server

2. Connect to your ABAP projects

The view shows all ABAP projects in your workspace. Click Connect All to connect to every project at once, or select a project and click Connect to connect individually. The plugin reuses each project's existing ADT session — no password prompt.

3. Start the server

Click Start Server. The embedded MCP server starts on http://127.0.0.1:3000/mcp (port is configurable). It binds to localhost only and is not accessible from the network.

4. Configure your MCP client

Add the following to your client's MCP configuration:

{
  "mcpServers": {
    "abap-adt": {
      "type": "streamable-http",
      "url": "http://127.0.0.1:3000/mcp"
    }
  }
}

Claude Code — add to .claude/settings.json or ~/.claude/settings.json:

{
  "mcpServers": {
    "abap-adt": {
      "type": "streamable-http",
      "url": "http://127.0.0.1:3000/mcp"
    }
  }
}

5. Verify

Check the health endpoint in your browser or with curl:

GET http://127.0.0.1:3000/health

Port configuration

Window > Preferences > ABAP MCP Server — change the server port or enable auto-start when you connect to a project.

Multi-System Support

When multiple ABAP projects are connected, pass systemId (the Eclipse project name) to route a tool call to the right system:

{ "query": "ZCL*", "systemId": "ER1_001" }

Single system connected — systemId is optional; the call is routed automatically.
Multiple systems connected — systemId is required. Omitting it returns an error listing the available systems.
sap_list_systems — call this tool at any time to see which systems are currently connected.

The systemId description in every tool's schema is dynamically populated from the live registry, so the AI always knows which systems are available.

MCP Tools

The plugin exposes 17 tools covering the full ABAP development workflow:

Tool	Description
`sap_search_object`	Search for ABAP objects by name pattern and/or type
`sap_object_structure`	Get the structure and metadata of an object (includes, links, source URLs)
`sap_usage_references`	Find all where-used references for an object
`sap_inactive_objects`	List objects that are currently inactive (not yet activated)

Read & Write Source

Tool	Description
`sap_pull_source`	Read source code of an ABAP object directly into the AI context
`sap_pull_source_to_file`	Fetch source from SAP and write it to a local file (preferred for large objects)
`sap_push_source`	Write source code from context to an ABAP object in SAP
`sap_push_source_from_file`	Save a local file back to SAP (lock → write → unlock → activate pipeline)

Lifecycle

Tool	Description
`sap_lock`	Lock an object for editing (returns a lock handle)
`sap_unlock`	Release a previously acquired lock
`sap_activate`	Activate an ABAP object
`sap_create_object`	Create a new ABAP object: class, interface, program, function group, data element, table, structure, or CDS view

Quality & Testing

Tool	Description
`sap_syntax_check`	Run a syntax check and return errors and warnings with line numbers
`sap_run_unit_test`	Execute ABAP Unit tests and return pass/fail results
`sap_atc_run`	Run ATC (ABAP Test Cockpit) checks and return quality findings

Data

Tool	Description
`sap_sql_query`	Execute an ABAP SQL query and return the results as JSON

Systems

Tool	Description
`sap_list_systems`	List all SAP systems currently connected and available for tool calls
