Why we included this project

Teams wiring AI agents to their databases can skip a lot of boilerplate with this MCP server. It ships prebuilt tools for schema exploration, structured queries, semantic search, and natural-language-to-SQL that any MCP-compatible client, from Gemini CLI to Claude Code to Codex, can call directly. The same project doubles as a framework for building your own secure, specialized database tools for production agents, with restricted access and structured query definitions built in. That dual nature suits both quick prototyping against Postgres, MySQL, BigQuery, and a long list of other engines, and hardening those capabilities for real workloads. Connection pooling, IAM-style auth, and OpenTelemetry observability are handled out of the box, so you don't have to build that plumbing yourself.
