How to Set Up and Use SAP RFC
The SAP RFC MCP Server bridges AI assistants with SAP systems through Remote Function Call (RFC) connections, allowing Claude and other MCP clients to invoke RFC functions, search SAP function metadata, and retrieve table data directly from R/3 through S/4HANA landscapes. It is written in Python and requires the SAP NetWeaver RFC SDK alongside a network-accessible SAP application server.
Prerequisites
- Python 3.9 or higher installed
- SAP NetWeaver RFC SDK downloaded from SAP Service Marketplace and installed
- Access to an RFC-enabled SAP system (R/3 4.5B through S/4HANA)
- SAP user account with RFC authorization (S_RFC object)
- Git installed to clone the repository
Clone the repository
Clone the sap-rfc-mcp-server repository to your local machine and enter the project directory.
git clone https://github.com/thupalo/sap-rfc-mcp-server.git
cd sap-rfc-mcp-serverRun the automated setup script
Use the provided setup script to install all Python dependencies and create the initial configuration. Alternatively, install manually with pip.
python tools/setup_dev.py
# or manually:
pip install -e .Configure SAP connection credentials
Create a .env file in the project root with your SAP system details. Use the security manager to store credentials securely and verify connectivity.
# .env file
SAP_ASHOST=your-sap-host.example.com
SAP_SYSNR=00
SAP_CLIENT=100
SAP_USER=your_sap_user
SAP_PASSWD=your_password
SAP_LANG=EN
SAP_POOL_SIZE=5
# Then test the connection:
python -m sap_rfc_mcp_server.sap_security_manager setup
python -m sap_rfc_mcp_server.sap_security_manager testStart the MCP server
Launch the server using the smart startup script that handles port management, or start the MCP server directly for stdio transport.
# Recommended: smart start with port management
python tools/start_mcp_smart.py
# Or start directly:
python -m sap_rfc_mcp_server.server
# Or as HTTP API on a specific host/port:
python -m sap_rfc_mcp_server.http_server 127.0.0.1 8000Add to Claude Desktop configuration
Register the server in your Claude Desktop config so it is available as an MCP tool. Adjust the python path to match your virtual environment if needed.

Example prompts you can use with the SAP RFC MCP Server once configured.
- "Search for RFC functions related to material master data in SAP"
- "Call RFC_READ_TABLE to fetch the first 10 rows from table T001 (company codes)"
- "Get the metadata and parameter descriptions for function module BAPI_MATERIAL_GET_DETAIL"
- "List all available RFC function modules related to purchase orders"
- "Retrieve the function group and import/export parameters for RFC_GET_STRUCTURE_DEFINITION"Troubleshooting SAP RFC
ImportError or 'pyrfc not found' when starting the server
The pyrfc Python library requires the SAP NetWeaver RFC SDK to be installed first. Download the SDK from SAP Service Marketplace (search for 'SAP NW RFC SDK'), extract it, and set the SAPNWRFC_HOME environment variable to the SDK root before running pip install pyrfc.
RFC connection fails with authorization error or RFC_NOT_AUTHORIZED
Ensure the SAP user has S_RFC authorization object with RFC_TYPE FUGR and the relevant function groups. Ask your SAP Basis team to assign the correct authorization profile. Also verify SAP_CLIENT, SAP_SYSNR, and SAP_ASHOST values are correct for your landscape.
Server starts but Claude cannot connect to it
Verify the cwd in the Claude Desktop config points to the cloned repository directory and that the python executable path matches your virtual environment. Run python -m sap_rfc_mcp_server.server manually in a terminal to check for startup errors before adding it to the MCP config.
