faucet vs mcp_on_ruby

faucet: Faucet is a single Go binary that transforms any SQL database into a secure REST API and an MCP server for AI agents, offering instant data access with authentication and role-based access control. It automatically introspects database schemas to generate full CRUD APIs and OpenAPI documentation, significantly accelerating backend development and AI agent data integration.; mcp_on_ruby: MCP on Ruby is a gem that transforms Rails applications into AI-accessible interfaces using the Model Context Protocol. It allows developers to define callable tools and expose data resources, enabling AI models to interact with and automate actions within Rails apps securely and efficiently.
