barbacane vs mcp-server

barbacane: Barbacane is a spec-driven API gateway built in Rust. It uses OpenAPI/AsyncAPI specs as configuration, compiles them into sealed artifacts, and provides routing, validation, authentication, AI traffic management, and MCP support. It features fast performance, security by default, and an extensible plugin system.; mcp-server: A Model Context Protocol (MCP) server for the SAP Cloud Application Programming Model (CAP). It enables AI models to perform agentic coding by searching CDS model definitions and CAP documentation. The server runs locally and integrates with MCP-compatible clients.
