barbacane vs mcp-use
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-use: mcp-use is a full-stack framework for Model Context Protocol (MCP), enabling the creation of MCP servers, clients, and AI agents. It supports development in both Python and TypeScript with minimal code.
