ARC-1

Overview

ARC-1 is a Model Context Protocol server that connects AI assistants directly to SAP ABAP systems. Any MCP-compatible client can call ARC-1's tools to interact with your SAP environment, letting the model decide when and how to use them during conversations or agent runs.

The server runs locally via the npm package arc-1, which communicates over stdio on your machine. You'll need to provide SAP_URL, SAP_USER, and SAP_PASSWORD as environment variables to authenticate. Version 1.1.0 is the latest release, available under the MIT license with source code at arc-mcp/arc-1 on GitHub, where it has 174 stars.

ARC-1 is categorized as a Development tool on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain ARC-1 for arc-mcp, you can claim this listing to verify ownership and keep the information up to date.
