Simplifier MCP Server

Simplifier is the leading low-code platform in the SAP ecosystem. Build custom apps in a full-stack low-code cloud development environment, reducing your dependency on full-scale coding. Integrate with ERP, CRM and other systems easily using standardised connectors.

Find more information in our community or try Simplifier for free.

This repository contains an MCP server (Model Context Protocol) that enables integration of AI assistants with the Simplifier Low Code Platform. It provides tools and resources for creating and managing Simplifier Connectors and BusinessObjects.

Overview

The Simplifier MCP Server allows to interact with a Simplifier instance to:

• Manage Connectors and Logins: Integration components that connect external systems
• Manage Business Objects: Server-side executed JavaScript functions for business logic
• Manage Data Types: Data structures for interacting with Connectors and internal objects
• Execute Business Object Functions: Run JavaScript functions with parameters and retrieve results
• Execute Connector Calls: Call external systems via Simplifier Connector
• Access platform resources: Browse connectors, business objects, and system information

Usage

Check out Simplifier Community Docs on how to use and set up the MCP server best.

Add the MCP to claude code ...

Using node / npx:

claude mcp add simplifier npx @simplifierag/simplifier-mcp@latest --env SIMPLIFIER_TOKEN=<your current simplifier token> --env SIMPLIFIER_BASE_URL=https://<yourinstance>-dev.simplifier.cloud

Using Docker:

claude mcp add simplifier-docker docker -- run --rm -i --env SIMPLIFIER_TOKEN=<your current simplifier token> --env SIMPLIFIER_BASE_URL=https://<yourinstance>-dev.simplifier.cloud simplifierag/simplifier-mcp:latest

If your Simplifier is hosted on premise, then the SIMPLIFIER_BASE_URL of your DEV instance will be different from the mentioned schema.

After a new login to Simplifier

With every login to Simplifier your SimplifierToken will change. So you will have to:

• exit your AI agent (in this example claude),
• then remove the configuration of the MCP

claude mcp remove simplifier

• and then add the MCP again with the new token (see upper command) and restart your AI agent

...or use this example configuration for claude code to use the MCP

e.g. in a file named .mcp.json placed in the directory, where claude is started.

Using node / npx:

{
  "mcpServers":  {
    "simplifier-mcp": {
      "type": "stdio",
      "command": "npx",
      "args": [ 
        "@simplifierag/simplifier-mcp@latest"
      ],
      "env": {
        "SIMPLIFIER_BASE_URL": "https://<yourinstance>-dev.simplifier.cloud",
        "SIMPLIFIER_TOKEN": "<your current simplifier token>"
      }
    }
  }
}

Using Docker:

{
  "mcpServers": {
    "simplifier-docker": {
      "type": "stdio",
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "--env",
        "SIMPLIFIER_TOKEN",
        "--env",
        "SIMPLIFIER_BASE_URL",
        "simplifierag/simplifier-mcp:latest"
      ],
      "env": {
        "SIMPLIFIER_BASE_URL": "https://<yourinstance>-dev.simplifier.cloud",
        "SIMPLIFIER_TOKEN": "<your current simplifier token>"
      }
    }
  }
}

Troubleshooting

If the MCP fails to connect to Simplifier on startup, an error page will open in your browser with details on the failure and information on how to fix the problem.
