ARC-1 MCP

ARC-1 is an enterprise-ready TypeScript MCP server that acts as a proxy between AI clients and SAP ABAP systems. It translates AI tool calls into SAP ABAP Development Tools (ADT) REST API requests, enabling secure AI-assisted development. It supports Claude, GitHub Copilot, VS Code, and other MCP-compatible clients, offering granular security controls like default deny, package restrictions, and rate limiting.
