sap-abap-mcp

A custom MCP server that connects IBM Bob to any SAP ABAP system via SOAP/RFC and SAP WebGUI (ITS).

No SAP system details are hardcoded — everything is configured through environment variables, so each user connects to their own system with their own credentials.

Prerequisites

• Node.js v18 or later

• Git (to clone)

• IBM Bob IDE extension installed

• A valid SAP user account on the target system

Setup (first time)

Option A — via npx (easiest, no clone needed)

No installation required. Just set your environment variables (Step 3 below) and open the folder in Bob — npx will automatically download and run the latest version.

Option B — via GitHub clone (for development / offline use)

git clone https://github.com/JayGandhi285/sap-abap-mcp.git
cd sap-abap-mcp
npm install
npm run build

Then in .bob/mcp.json, change the command from npx to node and args to ["./build/index.js"].

3. Set your SAP connection details as environment variables

These five variables tell the server which SAP system to connect to and how to log in. Each person sets their own — never share credentials.

Windows PowerShell — add to your $PROFILE for persistence:

$env:SAP_WEBGUI_URL = "https://your-sap-host/sap/bc/gui/sap/its/webgui"
$env:SAP_CLIENT     = "100"
$env:SAP_USERNAME   = "your_sap_username"
$env:SAP_PASSWORD   = "your_sap_password"
$env:SAP_LANGUAGE   = "EN"

Mac / Linux — add to ~/.zshrc or ~/.bashrc:

export SAP_WEBGUI_URL="https://your-sap-host/sap/bc/gui/sap/its/webgui"
export SAP_CLIENT="100"
export SAP_USERNAME="your_sap_username"
export SAP_PASSWORD="your_sap_password"
export SAP_LANGUAGE="EN"

⚠️ The server will refuse to start and print a clear error message if any required variable is missing.

4. Open the sap-abap-mcp folder in Bob

Bob automatically detects .bob/mcp.json in the workspace root and connects to the server. The SAP tools will appear in Bob's tool list immediately.

Available tools

Example prompts in Bob

Show me all users in the SAP system
Read table T001 and show the company codes
Show me all failed background jobs
List all transport requests owned by RAJAT

How it works

• SOAP/RFC (sap_rfc_read_table, sap_se16_browse): Uses RFC_READ_TABLE via SOAP with HTTP Basic Auth — stateless, no login session needed.

• WebGUI session (sap_login, sap_navigate, etc.): Performs a full login via SAP ITS WebGUI and keeps session cookies in a local temp file.

Rebuilding after source changes

npm run build

Then in Bob: Settings → MCP → Restart server.

Updating to the latest version

git pull
npm install
npm run build

Security notes

• ✅ No credentials or system URLs are hardcoded anywhere in the source.

• ✅ .gitignore excludes build/, node_modules/, session files, and data dumps.

• ✅ .bob/mcp.json contains only ${ENV_VAR} placeholders — safe to commit to Git.

• ⚠️ Never add real credentials to any file that gets committed to Git.
