Faucet: REST API and MCP server for any SQL database

Turn any SQL database into a secure REST API and MCP server.
One binary. One command.

Faucet is an open-source (MIT) single Go binary that turns PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, Snowflake or SQLite into a REST API and an MCP server for AI agents, with role-based access control (RBAC), OpenAPI 3.1 and a built-in admin UI.

Endpoints, OpenAPI specs and MCP tools are generated from your database schema at runtime. No code generation, no ORM, no boilerplate.
