SAPient MCP

Intelligent SAP GUI automation for AI agents

A production-ready Model Context Protocol (MCP) server that enables LLMs (Claude, Copilot, Cursor, etc.) to automate SAP GUI using the RoboSAPiens library.

Compatible MCP Clients

Client	Mode	Notes
Claude Desktop	stdio	Full support
Claude Code	stdio	Full support
Cursor	stdio or SSE	Full support
VS Code (GitHub Copilot)	stdio or SSE	Requires Copilot agent mode
Windsurf	stdio or SSE	Full support
Any MCP client	SSE/HTTP	Via --port flag

---

Prerequisites

Requirement	Details
OS	Windows 10/11 only (SAP GUI is Windows-only)
Python	3.10 or newer
SAP GUI	SAP GUI for Windows installed
SAP Scripting	Must be enabled on server (RZ11: sapgui/user_scripting=TRUE) AND in SAP Logon client settings

Enable SAP GUI Scripting (one-time setup)

1. Open SAP Logon → Customize Local Layout (Alt+F12) → Options
2. Go to Accessibility & Scripting → Scripting
3. ✅ Enable scripting
4. ❌ Disable "Notify when a script attaches to a running SAP GUI session"
5. ❌ Disable "Notify when a script opens a connection"
6. Ask BASIS admin to run transaction RZ11 → set sapgui/user_scripting = TRUE

Quick Start

Option A — stdio mode (local clients)

SAPient MCP works with any MCP-compatible client. Pick yours below.

---

Claude Desktop

Edit %APPDATA%\Claude\claude_desktop_config.json:

{
  "mcpServers": {
    "sapient": {
      "command": "python",
      "args": ["-m", "sapient_mcp"],
      "env": {
        "SAPIENT_MCP_SAPLOGON_PATH": "C:\\Program Files (x86)\\SAP\\FrontEnd\\SAPgui\\saplogon.exe",
        "SAPIENT_MCP_CAPS": "screenshot,codegen,advanced",
        "SAPIENT_MCP_OUTPUT_DIR": "C:\\sapient_output"
      }
    }
  }
}

---

Claude Code (CLI)

claude mcp add sapient python -m sapient_mcp \
  -- --caps screenshot,codegen,advanced

Or edit ~/.claude/mcp.json / .claude/mcp.json in your project root:

{
  "mcpServers": {
    "sapient": {
      "command": "python",
      "args": ["-m", "sapient_mcp", "--caps", "screenshot,codegen,advanced"],
      "env": {
        "SAPIENT_MCP_SAPLOGON_PATH": "C:\\Program Files (x86)\\SAP\\FrontEnd\\SAPgui\\saplogon.exe",
        "SAPIENT_MCP_OUTPUT_DIR": "C:\\sapient_output"
      }
    }
  }
}

---

Cursor

Go to Cursor Settings → MCP → Add new MCP Server → type command, then enter:

python -m sapient_mcp --caps screenshot,codegen,advanced

Or edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "sapient": {
      "command": "python",
      "args": ["-m", "sapient_mcp", "--caps", "screenshot,codegen,advanced"],
      "env": {
        "SAPIENT_MCP_SAPLOGON_PATH": "C:\\Program Files (x86)\\SAP\\FrontEnd\\SAPgui\\saplogon.exe",
        "SAPIENT_MCP_OUTPUT_DIR": "C:\\sapient_output"
      }
    }
  }
}

---

VS Code (GitHub Copilot)

Install the MCP server via VS Code CLI:

code --add-mcp '{"name":"sapient","command":"python","args":["-m","sapient_mcp","--caps","screenshot,codegen,advanced"]}'

Or add to .vscode/mcp.json in your workspace:

{
  "servers": {
    "sapient": {
      "type": "stdio",
      "command": "python",
      "args": ["-m", "sapient_mcp", "--caps", "screenshot,codegen,advanced"],
      "env": {
        "SAPIENT_MCP_SAPLOGON_PATH": "C:\\Program Files (x86)\\SAP\\FrontEnd\\SAPgui\\saplogon.exe",
        "SAPIENT_MCP_OUTPUT_DIR": "C:\\sapient_output"
      }
    }
  }
}

---

Windsurf

Edit ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "sapient": {
      "command": "python",
      "args": ["-m", "sapient_mcp", "--caps", "screenshot,codegen,advanced"],
      "env": {
        "SAPIENT_MCP_SAPLOGON_PATH": "C:\\Program Files (x86)\\SAP\\FrontEnd\\SAPgui\\saplogon.exe",
        "SAPIENT_MCP_OUTPUT_DIR": "C:\\sapient_output"
      }
    }
  }
}

---

Note: In stdio mode, SAPient MCP never writes to stdout or stderr — all logs go to the log file only. This is required for clean JSON-RPC communication across all clients.

Option B — SSE/HTTP mode (remote / CI / multi-user)

Best when the SAP machine is separate from where the AI client runs, or when multiple developers want to share one SAPient instance.

Run the server on your Windows SAP machine:

python -m sapient_mcp --port 8765 --caps screenshot,codegen,advanced

Then point any MCP client at the HTTP endpoint:

{
  "mcpServers": {
    "sapient": {
      "url": "http://sap-windows-machine:8765/mcp"
    }
  }
}

This works identically in Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and any other MCP-compatible client.

Option C — Config file

python -m sapient_mcp --config C:\sap_config.json

Example LLM Conversation

You: Create a purchase order for vendor 100001, company code 1000, with 50 units of material ABC-001

SAPient will guide the LLM to:

1. Call sap_execute_transaction("/nME21N")
2. Call sap_get_window_title() → "Create Purchase Order"
3. Call sap_fill_text_field("Vendor", "100001")
4. Call sap_fill_text_field("Company Code", "1000")
5. Call sap_send_key("Enter") to accept header
6. Call sap_activate_tab("Item Overview")
7. Call sap_fill_cell("1", "Material", "ABC-001")
8. Call sap_fill_cell("1", "Quantity", "50")
9. Call sap_push_button("Save")
10. Call sap_read_status_bar() → "Purchase order 4500001234 created"

Logs

Logs are written to {output_dir}/sapient_mcp.log.

In stdio mode, logs never go to stdout/stderr (would break JSON-RPC). In SSE mode, logs also appear on stderr.
