How do I use ABAP MCP?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@ABAP MCP generate a CDS view for sales order header with customer join" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

ABAP MCP – AI-Powered SAP Development

An ABAP Model Context Protocol (MCP) server that brings AI-driven coding assistance to SAP ABAP development. Works with VS Code Copilot, Claude Desktop, Cursor, and any MCP-compatible client. Supports multiple LLM backends including GitHub Copilot, OpenAI, Anthropic Claude, Azure OpenAI, and local models via Ollama.

SAP_PASSWORD=secret
SAP_CLIENT=100
SAP_LANGUAGE=EN

Development

npm run dev          # Run server in development mode (tsx, no build)

Adding a New LLM Provider

Create src/llm/my-provider.ts implementing LLMProvider:

export class MyProvider implements LLMProvider {
  readonly name = 'my-provider';
  readonly model: string;

  async complete(messages, options) { /* ... */ }
  async *stream(messages, options) { /* ... */ }
  async healthCheck() { /* ... */ }
}

Register it in src/llm/factory.ts under a new case.
Add the new provider to the LLM_PROVIDER enum in src/utils/config.ts.
Add a VS Code setting entry in vscode-extension/package.json.
