faucet vs kru

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.; kru: KRU is a free, open-source, local-first credential manager and MCP server designed for AI agents. It enables agents to securely use passwords, API keys, and SSH credentials for various tasks without exposing plaintext to the model context.
